Hi All,
    In my quest to build a Universal binary of Subversion I have found an issue with apr-util not handling LDFLAGS settings properly.  To explain, let's look at my problem.  When I use the following configure script call, not all of the linker flags are being passed:

./configure --prefix=/Users/jwhitlock/dev/subversion_binary/binary/apr-util --with-apr=/Users/jwhitlock/dev/subversion_binary/binary/apr --with-berkeley-db=/Users/jwhitlock/dev/subversion_binary/binary/bdb --without-pgsql --without-sqlite3 --without-sqlite2 --disable-dependency-tracking CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc" LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk"

What happens is the "-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk" flags are not passed and I get the following error:

ld: Undefined symbols:
_fegetround referenced from libSystem expected to be defined in /usr/lib/system/libmathCommon.A.dylib
/usr/bin/libtool: internal link edit command failed
lipo: can't figure out the architecture type of: /var/tmp//ccPKIOat.out
make[1]: *** [libaprutil-1.la] Error 1
make: *** [all-recursive] Error 1

To prove my theory, here is the problematic libtool call:

/bin/sh /Users/jwhitlock/dev/subversion_binary/binary/apr/build-1/libtool --silent --mode=link  gcc   -O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -DHAVE_CONFIG_H -DDARWIN -DSIGPROCMASK_SETS_THREAD_MASK -no-cpp-precomp   -I/Users/jwhitlock/dev/subversion_binary/sources/httpd- 2.2.4/srclib/apr-util/include -I/Users/jwhitlock/dev/subversion_binary/sources/httpd-2.2.4/srclib/apr-util/include/private  -I/Users/jwhitlock/dev/subversion_binary/binary/apr/include/apr-1  -I/Users/jwhitlock/dev/subversion_binary/binary/bdb/include -I/Users/jwhitlock/dev/subversion_binary/sources/httpd- 2.2.4/srclib/apr-util/xml/expat/lib  -version-info 2:8:2   -arch i386 -arch ppc -o libaprutil-1.la -rpath /Users/jwhitlock/dev/subversion_binary/binary/apr-util/lib buckets/apr_buckets_pipe.lo buckets/apr_buckets_flush.lo buckets/apr_buckets_alloc.lo buckets/apr_buckets_pool.lo buckets/apr_buckets_socket.lo buckets/apr_buckets_heap.lo buckets/apr_buckets_simple.lo buckets/apr_buckets_file.lo buckets/apr_buckets.lo buckets/apr_buckets_mmap.lo buckets/apr_buckets_eos.lo buckets/apr_brigade.lo buckets/apr_buckets_refcount.lo crypto/apr_sha1.lo crypto/uuid.lo crypto/getuuid.lo crypto/apr_md5.lo crypto/apr_md4.lo dbm/apr_dbm.lo dbm/apr_dbm_berkeleydb.lo dbm/apr_dbm_gdbm.lo dbm/apr_dbm_ndbm.lo dbm/apr_dbm_sdbm.lo dbm/sdbm/sdbm_pair.lo dbm/sdbm/sdbm.lo dbm/sdbm/sdbm_hash.lo dbm/sdbm/sdbm_lock.lo encoding/apr_base64.lo hooks/apr_hooks.lo ldap/apr_ldap_url.lo ldap/apr_ldap_option.lo ldap/apr_ldap_init.lo misc/apr_reslist.lo misc/apu_version.lo misc/apr_date.lo misc/apr_rmm.lo misc/apr_queue.lo uri/apr_uri.lo xml/apr_xml.lo strmatch/apr_strmatch.lo xlate/xlate.lo dbd/apr_dbd.lo dbd/apr_dbd_sqlite2.lo dbd/apr_dbd_sqlite3.lo dbd/apr_dbd_pgsql.lo   -lpthread -L/Users/jwhitlock/dev/subversion_binary/binary/bdb/lib -L/Users/jwhitlock/dev/subversion_binary/sources/httpd- 2.2.4/srclib/apr-util/xml/expat/lib -ldb-4.5 /Users/jwhitlock/dev/subversion_binary/sources/httpd-2.2.4/srclib/apr-util/xml/expat/lib/libexpat.la -liconv /Users/jwhitlock/dev/subversion_binary/binary/apr/lib/libapr- 1.la -lpthread

When I add the missing libtool flags to the end of the libtool call above, apr-util links properly as a universal library.  The better way to do this is to update the Makefile and append the missing flags to the APRUTIL_LDFLAGS.

Now that we are on the same page, how does one verify that this worthy of a bug report or feature request?  I really think this should be documented since it appears that the LDFLAGS passed to configure, or as an environment variable for that matter, are disregarded.  Where do we go from here?

Take care,

Jeremy
