GCC compiler on Mac OS X 10.4.6 Tiger (Darwin) does not understand -shared option.
----------------------------------------------------------------------------------

         Key: STDCXX-194
         URL: http://issues.apache.org/jira/browse/STDCXX-194
     Project: C++ Standard Library
        Type: Bug

  Components: Build  
    Versions: 4.1.3, 4.1.4    
 Environment: Darwin machine.local 8.6.1 Darwin Kernel Version 8.6.1: Tue Mar  7 16:55:45

Sample build:

machine:~/Work/stdcxx user$ make BUILDDIR=~/Build/stdcxx BUILDMODE=debug,shared,pthreads
machine:~/Work/stdcxx user$ cd ~/Build/stdcxx
machine:~/Build/stdcxx user$ find . -exec grep -H -- -shared {} \;

./include/vars.sh:LDSOFLAGS=-shared ; export LDSOFLAGS

Here's a patch for it:

*** gcc.config.2        Fri Jun  2 10:26:53 2006
--- gcc.config  Fri Jun  2 11:04:19 2006
***************
*** 62,68 ****
--- 62,71 ----
    endif
  endif
  
+ # No -shared option for GCC on Mac OS X (Darwin).
+ ifneq ($(OSNAME),Darwin)
  LDSOFLAGS       = -shared
+ endif
  
  # -fPIC needed both to compile and link shared libs on HP-UX 11
  ifeq ($(OSNAME),HP-UX)
