Thanks for all the answers. They are helping me learn more. I looked in the config.log for linker to shared libraries: configure:11966: checking whether the gcc linker (/usr/bin/ld) supports shared libraries configure:12589: gcc -o conftest -g -O2 -O2 -pg -pthread -U__STR__ -D_THREAD_SAFE -D_LARGEFILE64_SOURCE -L/opt/freeware/lib conftest.c >&5 configure:12589: $? = 0 configure:13225: result: yes configure:13465: checking dynamic linker characteristics configure:14283: result: AIX lib.a(lib.so.V) configure:14405: checking how to hardcode library paths into programs configure:14430: result: immediate configure:14978: checking whether stripping libraries is possible configure:15000: result: no configure:15018: checking if libtool supports shared libraries configure:15020: result: yes configure:15023: checking whether to build shared libraries configure:15048: result: yes configure:15051: checking whether to build static libraries configure:15055: result: no configure:15340: checking for ld used by g++ configure:15407: result: /usr/bin/ld configure:15414: checking if the linker (/usr/bin/ld) is GNU ld configure:15429: result: no configure:15484: checking whether the g++ linker (/usr/bin/ld) supports shared libraries configure:15691: g++ -o conftest -g -O2 -U__STR__ -D_THREAD_SAFE -D_LARGEFILE64_SOURCE -L/opt/freeware/lib conftest.cpp >&5 ld: 0711-224 WARNING: Duplicate symbol: .__divdi3 ld: 0711-224 WARNING: Duplicate symbol: .__moddi3 ld: 0711-224 WARNING: Duplicate symbol: .__udivdi3 ld: 0711-224 WARNING: Duplicate symbol: .__umoddi3 ld: 0711-224 WARNING: Duplicate symbol: .__udivmoddi4 ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. configure:15691: $? = 0 configure:16557: result: yes . configure:17319: checking whether the g++ linker (/usr/bin/ld) supports shared libraries configure:17359: result: yes configure:17500: checking dynamic linker characteristics configure:18245: result: AIX lib.a(lib.so.V) configure:18310: checking how to hardcode library paths into programs configure:18335: result: immediate configure:18447: building shared libraries only configure:18495: checking whether libtool needs -no-undefined configure:18504: result: no . So, linker (usr/bin/ld) is not GNU ld g++ linker (usr/bin/ld)supports shared libraries (warnings?) gcc linker (usr/bin/ld)supports shared libraries libtool supports share libraries Yes to building shared libraries No to building static libraries.
Is there anything here that is not quite right?

Here is an old email that suggests which linker flags are needed to create .so, rather than .a, shared libraries: https://gcc.gnu.org/ml/gcc-help/2002-05/msg00065.html Perhaps edit your Makefile and add -Wl,-G to the end of the LINK_APACHE_MOD line. -- Philip
