求救 aix上 ACE 问题
原来在linux上测试的程序，打算移植到AIX 上测试。$ g++ -v
Reading specs from /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.3.0.0/3.3.2/specs
Configured with: ../configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/opt/freeware --enable-threads --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.3.0.0
Thread model: aix
gcc version 3.3.2
编译过程：
设置环境变量
export ACE_ROOT=/home/aceuser/ACE_wrappers
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ACE_ROOT/ace
#cd/home/aceuser/ACE_wrappers/ace/
#cp./config-aix-5.x.h ./config.h
#cd ../include/makeinclude/
#ln -s ./platform_aix_g++.GNU ./platform_macros.GNU
#cd /home/aceuser/ACE_wrappers/ace/
#make
生成库时,编译ACE是通过了，但连接时出现下面的问题：

请大家帮忙看看。 找了一下,不知道能否解决你的问题:

This definitely is a problem of linking against a different shared
library multilib than the one used at runtime.
The libxerces-c1_6_0.a library appears to have been built and
linked with -pthread option, but superman may not have been built that
way.-pthread uses .../lib/pthread/libstdc++.a, for wherever GCC was
installed..../lib/pthread/libstdc++.a has pthread_mutex_t symbols,
.../lib/libstdc++.a does not.
AIX does not have weak bindings of pthread functions for
non-pthread applications.One has to use -pthread consistently.
Either superman was compiled and linked differently, so the
built-in runtime LIBPATH is wrong, or the LIBPATH environment variable
explicitly is set and overriding the application LIBPATH to point to the
default shared library installation directory instead of the one
appropriate for the application.
