-Perftools-Specific Install Notes
-================================
-
-*** Building from source repository
-
-As of 2.1 gperftools does not have configure and other autotools
-products checked into it's source repository. This is common practice
-for projects using autotools.
-
-NOTE: Source releases (.tar.gz that you download from
-code.google.com/p/gperftools) still have all required files just as
-before. Nothing has changed w.r.t. building from .tar.gz releases.
-
-But, in order to build gperftools checked out from subversion
-repository you need to have autoconf, automake and libtool
-installed. And before running ./configure you have to generate it (and
-a bunch of other files) by running ./autogen.sh script. That script
-will take care of calling correct autotools programs in correct order.
-
-If you're maintainer then it's business as usual too. Just run make
-dist (or, preferably, make distcheck) and it'll produce .tar.gz or
-.tar.bz2 with all autotools magic already included. So that users can
-build our software without having autotools.
-
-
-*** NOTE FOR 64-BIT LINUX SYSTEMS
-
-The glibc built-in stack-unwinder on 64-bit systems has some problems
-with the perftools libraries.  (In particular, the cpu/heap profiler
-may be in the middle of malloc, holding some malloc-related locks when
-they invoke the stack unwinder.  The built-in stack unwinder may call
-malloc recursively, which may require the thread to acquire a lock it
-already holds: deadlock.)
-
-For that reason, if you use a 64-bit system, we strongly recommend you
-install libunwind before trying to configure or install gperftools.
-libunwind can be found at
-
-   http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99-beta.tar.gz
-
-Even if you already have libunwind installed, you should check the
-version.  Versions older than this will not work properly; too-new
-versions introduce new code that does not work well with perftools
-(because libunwind can call malloc, which will lead to deadlock).
-
-There have been reports of crashes with libunwind 0.99 (see
-http://code.google.com/p/gperftools/issues/detail?id=374).
-Alternately, you can use a more recent libunwind (e.g. 1.0.1) at the
-cost of adding a bit of boilerplate to your code.  For details, see
-http://groups.google.com/group/google-perftools/msg/2686d9f24ac4365f
-
-   CAUTION: if you install libunwind from the url above, be aware that
-   you may have trouble if you try to statically link your binary with
-   perftools: that is, if you link with 'gcc -static -lgcc_eh ...'.
-   This is because both libunwind and libgcc implement the same C++
-   exception handling APIs, but they implement them differently on
-   some platforms.  This is not likely to be a problem on ia64, but
-   may be on x86-64.
-
-   Also, if you link binaries statically, make sure that you add
-   -Wl,--eh-frame-hdr to your linker options. This is required so that
-   libunwind can find the information generated by the compiler
-   required for stack unwinding.
-
-   Using -static is rare, though, so unless you know this will affect
-   you it probably won't.
-
-If you cannot or do not wish to install libunwind, you can still try
-to use the built-in stack unwinder.  The built-in stack unwinder
-requires that your application, the tcmalloc library, and system
-libraries like libc, all be compiled with a frame pointer.  This is
-*not* the default for x86-64.
-
-If you are on x86-64 system, know that you have a set of system
-libraries with frame-pointers enabled, and compile all your
-applications with -fno-omit-frame-pointer, then you can enable the
-built-in perftools stack unwinder by passing the
---enable-frame-pointers flag to configure.
-
-Even with the use of libunwind, there are still known problems with
-stack unwinding on 64-bit systems, particularly x86-64.  See the
-"64-BIT ISSUES" section in README.
-
-If you encounter problems, try compiling perftools with './configure
---enable-frame-pointers'.  Note you will need to compile your
-application with frame pointers (via 'gcc -fno-omit-frame-pointer
-...') in this case.
-
-
-*** TCMALLOC LARGE PAGES: TRADING TIME FOR SPACE
-
-You can set a compiler directive that makes tcmalloc faster, at the
-cost of using more space (due to internal fragmentation).
-
-Internally, tcmalloc divides its memory into "pages."  The default
-page size is chosen to minimize memory use by reducing fragmentation.
-The cost is that keeping track of these pages can cost tcmalloc time.
-We've added a new flag to tcmalloc that enables a larger page size.
-In general, this will increase the memory needs of applications using
-tcmalloc.  However, in many cases it will speed up the applications
-as well, particularly if they allocate and free a lot of memory. We've
-seen average speedups of 3-5% on Google applications.
-
-To build libtcmalloc with large pages you need to use the
---with-tcmalloc-pagesize=ARG configure flag, e.g.:
-
-   ./configure <other flags> --with-tcmalloc-pagesize=32
-
-The ARG argument can be 8, 32 or 64 which sets the internal page size to
-8K, 32K and 64K repectively. The default is 8K.
-
-
-*** SMALL TCMALLOC CACHES: TRADING SPACE FOR TIME
-
-You can set a compiler directive that makes tcmalloc use less memory
-for overhead, at the cost of some time.
-
-Internally, tcmalloc keeps information about some of its internal data
-structures in a cache.  This speeds memory operations that need to
-access this internal data.  We've added a new, experimental flag to
-tcmalloc that reduces the size of this cache, decresaing the memory
-needs of applications using tcmalloc.
-
-This feature is still very experimental; it's not even a configure
-flag yet.  To build libtcmalloc with smaller internal caches, run
-
-   ./configure <normal flags> CXXFLAGS=-DTCMALLOC_SMALL_BUT_SLOW
-
-(or add -DTCMALLOC_SMALL_BUT_SLOW to your existing CXXFLAGS argument).
-
-
-*** NOTE FOR ___tls_get_addr ERROR
-
-When compiling perftools on some old systems, like RedHat 8, you may
-get an error like this:
-    ___tls_get_addr: symbol not found
-
-This means that you have a system where some parts are updated enough
-to support Thread Local Storage, but others are not.  The perftools
-configure script can't always detect this kind of case, leading to
-that error.  To fix it, just comment out the line
-   #define HAVE_TLS 1
-in your config.h file before building.
-
-
-*** TCMALLOC AND DLOPEN
-
-To improve performance, we use the "initial exec" model of Thread
-Local Storage in tcmalloc.  The price for this is the library will not
-work correctly if it is loaded via dlopen().  This should not be a
-problem, since loading a malloc-replacement library via dlopen is
-asking for trouble in any case: some data will be allocated with one
-malloc, some with another.  If, for some reason, you *do* need to use
-dlopen on tcmalloc, the easiest way is to use a version of tcmalloc
-with TLS turned off; see the ___tls_get_addr note above.
-
-
-*** COMPILING ON NON-LINUX SYSTEMS
-
-Perftools has been tested on the following systems:
-   FreeBSD 6.0 (x86)
-   FreeBSD 8.1 (x86_64)
-   Linux CentOS 5.5 (x86_64)

-   Linux Debian 5.0 (x86)
-   Linux Fedora Core 3 (x86)
-   Linux Fedora Core 4 (x86)
-   Linux Fedora Core 5 (x86)
-   Linux Fedora Core 6 (x86)

-   Mac OS X 10.4.8 (Tiger) (PowerPC)
-   Mac OS X 10.4.8 (Tiger) (x86)
-   Mac OS X 10.5 (Leopard) (x86)
-   Mac OS X 10.6 (Snow Leopard) (x86)
-   Solaris 10 (x86_64)
-   Windows XP, Visual Studio 2003 (VC++ 7.1) (x86)
-   Windows XP, Visual Studio 2005 (VC++ 8) (x86)
-   Windows XP, Visual Studio 2005 (VC++ 9) (x86)
-   Windows XP, Visual Studio 2005 (VC++ 10) (x86)
-   Windows XP, MinGW 5.1.3 (x86)
-   Windows XP, Cygwin 5.1 (x86)
-
-It works in its full generality on the Linux systems
-tested (though see 64-bit notes above).  Portions of perftools work on
-the other systems.  The basic memory-allocation library,
-tcmalloc_minimal, works on all systems.  The cpu-profiler also works
-fairly widely.  However, the heap-profiler and heap-checker are not
-yet as widely supported.  In general, the 'configure' script will
-detect what OS you are building for, and only build the components
-that work on that OS.
-
-Note that tcmalloc_minimal is perfectly usable as a malloc/new
-replacement, so it is possible to use tcmalloc on all the systems
-above, by linking in libtcmalloc_minimal.
-
-** FreeBSD:
-
-   The following binaries build and run successfully (creating
-   libtcmalloc_minimal.so and libprofile.so in the process):
-      % ./configure
-      % make tcmalloc_minimal_unittest tcmalloc_minimal_large_unittest \
-             addressmap_unittest atomicops_unittest frag_unittest \
-             low_level_alloc_unittest markidle_unittest memalign_unittest \
-             packed_cache_test stacktrace_unittest system_alloc_unittest \
-             thread_dealloc_unittest profiler_unittest.sh
-      % ./tcmalloc_minimal_unittest    # to run this test
-      % [etc]                          # to run other tests
-
-   Three caveats: first, frag_unittest tries to allocate 400M of memory,
-   and if you have less virtual memory on your system, the test may
-   fail with a bad_alloc exception.
-
-   Second, profiler_unittest.sh sometimes fails in the "fork" test.
-   This is because stray SIGPROF signals from the parent process are
-   making their way into the child process.  (This may be a kernel
-   bug that only exists in older kernels.)  The profiling code itself
-   is working fine.  This only affects programs that call fork(); for
-   most programs, the cpu profiler is entirely safe to use.
-
-   Third, perftools depends on /proc to get shared library
-   information.  If you are running a FreeBSD system without proc,
-   perftools will not be able to map addresses to functions.  Some
-   unittests will fail as a result.
-
-   Finally, the new test introduced in perftools-1.2,
-   profile_handler_unittest, fails on FreeBSD.  It has something to do
-   with how the itimer works.  The cpu profiler test passes, so I
-   believe the functionality is correct and the issue is with the test
-   somehow.  If anybody is an expert on itimers and SIGPROF in
-   FreeBSD, and would like to debug this, I'd be glad to hear the
-   results!
-
-   libtcmalloc.so successfully builds, and the "advanced" tcmalloc
-   functionality all works except for the leak-checker, which has
-   Linux-specific code:
-      % make heap-profiler_unittest.sh maybe_threads_unittest.sh \
-             tcmalloc_unittest tcmalloc_both_unittest \
-             tcmalloc_large_unittest              # THESE WORK
-      % make -k heap-checker_unittest.sh \
-                heap-checker-death_unittest.sh    # THESE DO NOT
-
-   Note that unless you specify --enable-heap-checker explicitly,
-   'make' will not build the heap-checker unittests on a FreeBSD
-   system.
-
-   I have not tested other *BSD systems, but they are probably similar.
-
-** Mac OS X:
-
-   I've tested OS X 10.5 [Leopard], OS X 10.4 [Tiger] and OS X 10.3
-   [Panther] on both intel (x86) and PowerPC systems.  For Panther
-   systems, perftools does not work at all: it depends on a header
-   file, OSAtomic.h, which is new in 10.4.  (It's possible to get the
-   code working for Panther/i386 without too much work; if you're
-   interested in exploring this, drop an e-mail.)
-
-   For the other seven systems, the binaries and libraries that
-   successfully build are exactly the same as for FreeBSD.  See that
-   section for a list of binaries and instructions on building them.
-
-   In addition, it appears OS X regularly fails profiler_unittest.sh
-   in the "thread" test (in addition to occassionally failing in the
-   "fork" test).  It looks like OS X often delivers the profiling
-   signal to the main thread, even when it's sleeping, rather than
-   spawned threads that are doing actual work.  If anyone knows
-   details of how OS X handles SIGPROF (via setitimer()) events with
-   threads, and has insight into this problem, please send mail to
-   google-perftools@googlegroups.com.
-
-** Solaris 10 x86:
-
-   I've only tested using the GNU C++ compiler, not the Sun C++
-   compiler.  Using g++ requires setting the PATH appropriately when
-   configuring.
-
-   % PATH=${PATH}:/usr/sfw/bin/:/usr/ccs/bin ./configure
-   % PATH=${PATH}:/usr/sfw/bin/:/usr/ccs/bin make [...]
-
-   Again, the binaries and libraries that successfully build are
-   exactly the same as for FreeBSD.  (However, while libprofiler.so can
-   be used to generate profiles, pprof is not very successful at
-   reading them -- necessary helper programs like nm don't seem
-   to be installed by default on Solaris, or perhaps are only
-   installed as part of the Sun C++ compiler package.)  See that
-   section for a list of binaries, and instructions on building them.
-
-** Windows  (MSVC, Cygwin, and MinGW):
-
-   Work on Windows is rather preliminary: we haven't found a good way
-   to get stack traces in release mode on windows (that is, when FPO
-   is enabled), so the heap profiling may not be reliable in that
-   case.  Also, heap-checking and CPU profiling do not yet work at
-   all.  But as in other ports, the basic tcmalloc library
-   functionality, overriding malloc and new and such (and even
-   windows-specific functions like _aligned_malloc!), is working fine,
-   at least with VC++ 7.1 (Visual Studio 2003) through VC++ 10.0,
-   in both debug and release modes.  See README.windows for
-   instructions on how to install on Windows using Visual Studio.
-
-   Cygwin can compile some but not all of perftools.  Furthermore,
-   there is a problem with exception-unwinding in cygwin (it can call
-   malloc, which can call the exception-unwinding-setup code, which
-   can lead to an infinite loop).  I've comitted a workaround to the
-   exception unwinding problem, but it only works in debug mode and
-   when statically linking in tcmalloc.  I hope to have a more proper
-   fix in a later release.  To configure under cygwin, run
-
-      ./configure --disable-shared CXXFLAGS=-g && make
-
-   Most of cygwin will compile (cygwin doesn't allow weak symbols, so
-   the heap-checker and a few other pieces of functionality will not
-   compile).  'make' will compile those libraries and tests that can
-   be compiled.  You can run 'make check' to make sure the basic
-   functionality is working.  I've heard reports that some versions of
-   cygwin fail calls to pthread_join() with EINVAL, causing several
-   tests to fail.  If you have any insight into this, please mail
-   google-perftools@googlegroups.com.
-
-   This Windows functionality is also available using MinGW and Msys,
-   In this case, you can use the regular './configure && make'
-   process.  'make install' should also work.  The Makefile will limit
-   itself to those libraries and binaries that work on windows.
-
-
-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory.  After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.
