I am trying to build STLPort on AIX 4.3.3. I have successfully built this package on AIX 5.1 (using GCC 3.2.2 as well).
On both machines I am using the native linker
Aix 4.3.3 -
./gcc -v
Configured with: ../gcc-3.2.2/configure --prefix=/usr/local/fbe/2.0 --with-stabs --enable-shared --enable-threads=posix --without-gnu-as --with-as=/usr/bin/as
Thread mode: aix
gcc version 3.2.2
Aix 5.1 - ./gcc -v Same as above
When I try to compile STLPort there is a crucial difference between what happens on AIX 5.1 and 4.3.3
4.3.3 -
/usr/local/fbe/2.0/bin/g++ -pthread -fexceptions -I../stlport -Wall -W -Wno-sign-compare -Wno-unused -Wno-uninitialized -ftemplate-depth-32 -D_REENTRANT -D__EXTENSIONS__ -O -fPIC dll_main.cpp -c -o ../lib/obj/GCC-AIX/ReleaseD/dll_main.o
Note: note warning are generated by above step
Alos, I am pretty sure that D_REENTRANT isn't required on AIX, but it is there nevertheless.
5.1 -
/usr/local/fbe/2.0/bin/g++ -fexceptions -I../stlport -Wall -W -Wno-sign-compare -Wno-unused -Wno-uninitialized -ftemplate-depth-32 -D_REENTRANT -D__EXTENSIONS__ -O -fPIC dll_main.cpp -c -o ../lib/obj/GCC-AIX/ReleaseD/dll_main.o

Notice all the warning generated. This turns out to be a good thing because I believe this is what is allowing AIX 5.1 to define the following symbol, while 4.3.3 fails to do some.
nm -C dll_main.o | grep Node_Alloc _ZN4_STL16_Node_Alloc_LockILb1ELi0EE7_S_lockE U - _ZN4_STL16_Node_Alloc_LockILb1ELi0EE7_S_lockE d 83260 4
AIX 5.1 - nm -C dll_main.o | grep Node_Alloc _ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_lockE D 72980 _ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_LockE U - _ZN4_STL16_Node_Alloc_LockILb1Eli0EE7_S_LockE d 83984
When I try to link a helloWorld program on Aix 4.3.3 it fails with the following message
ERROR: Undefined symbol: _STL::_Node_Alloc_Lock<(bool)1, (int)0>::_S_lock
A side note is that I installed GNUPro 2.95 to get more information. When I compile dll_main.cpp with GNUPro the Node_Alloc symbol is defined as expected. I have other reasons for not wanting to using GNUPro as my final choice for compiler, so I need to get GCC 3.2.2 working.
FYI, I applied *APAR* IY26685 to my AIX 4.3.3 system.
I can't seem to nail this down.
Thanks, Paul
