I'm trying to build and test Boost on AIX 5.3, with gcc 3.3.2, but not getting very far. I'm focusing on the filesystem library, using the following build command: $ bjam "-sTOOLS=gcc" "-sBUILD=release debug <threading>single/multi <runtime-link>static/dynamic <linkflags>-pthread" --without-python --with-filesystem stage Without "<linkflags>-pthread", it fails with errors like "Undefined symbol: .pthread_mutex_lock". So, this command seems to work okay, although I do get the following linker warnings for all four .so links: ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__F_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__I_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: ._GLOBAL__D_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__I_thread_creds_t ld: 0711-224 WARNING: Duplicate symbol: _GLOBAL__D_thread_creds_t Then I want to verify the build, so I cd down into libs/filesystem/test, and try to run the test there by executing the following (the <linkflags>-pthread still seems to be required): $ bjam "-sBUILD=<linkflags>-pthread" The first problem I run into is this: ld: 0706-006 Cannot find or open library file: -l boost_filesystem-gcc-d-1_33_1 In the only "-L" directory listed in the g++ command line printed out after that ("../../../bin/boost/libs/filesystem/build/libboost_filesystem.so/gcc/debug/shared-linkable-true"), there is a libboost_filesystem-gcc-d-1_33_1.so, but no libboost_filesystem-gcc-d-1_33_1.a. So I manually copy the built libboost_filesystem-gcc-d-1_33_1.a from "../../../stage/lib", and try the same bjam command again. This time, the build part seems to work, though it gives the same linker warnings shown above for 2 of the 7 links ("../../../bin/boost/libs/filesystem/test/path_test_dll.test/gcc/debug/path_test_dll" and "../../../bin/boost/libs/filesystem/test/operations_test_dll.test/gcc/debug/operations_test_dll"). Then it tries to run the first test, but immediately crashes: execute-test ../../../bin/boost/libs/filesystem/test/path_test.test/gcc/debug/path_test.run ====== BEGIN OUTPUT ====== Platform is POSIX /data2/cgrayson/boost_1_33_1/boost/test/minimal.hpp(122): exception "signal: SIGABRT (application abort requested)" caught in function: 'int main(int, char**)' **** Testing aborted. **** 1 error detected EXIT STATUS: 201 ====== END OUTPUT ====== Any help would be greatly appreciated - thanks.
