Hello, I am trying to build libboost_filesystem.a on AIX-5.3 with gcc-4.3.1. The compilation goes right but unfortunately, I have the following error at the runtime (and a core file): "IOT/Abort trap (core dumped)" When I remove this library from my tiny example, my binary works; when I link against libboost_filesystem.a (even if functions are never called), it crashes. I tried a lot of options found on the web without success. Maybe someone her will be able to help me of guide me. Here the compilation of libboost_filesystem.a: ========== libboost_filesystem.a [begin] ========== ( cd libs/filesystem/src ; make ) g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c exception.cpp -o exception.o g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c path.cpp -o path.o g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c utf8_codecvt_facet.cpp -o utf8_codecvt_facet.o g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c operations.cpp -o operations.o g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c portability.cpp -o portability.o ar -X64 rv ../../../libboost_filesystem.a exception.o path.o utf8_codecvt_facet.o operations.o portability.o ar: Creating an archive file ../../../libboost_filesystem.a. a - exception.o a - path.o a - utf8_codecvt_facet.o a - operations.o a - portability.o ( cd libs/system/src ; make ) g++ -fPIC -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -DBOOST_ALL_NO_LIB -DBOOST_LIB_DIAGNOSTIC -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_UBLAS_INLINE=inline -D_THREAD_SAFE -DFFT_BUILDSYSTEM_GENERATOR -DNDEBUG -I../../.. -c error_code.cpp ar -X64 rv ../../../libboost_system.a error_code.o ar: Creating an archive file ../../../libboost_system.a. a - error_code.o ========== libboost_filesystem.a [end] ========== Here the compilation of my tiny test case (named "foo"): ========== foo [begin] ========== g++ -pthread -g -maix64 -Wall -Wno-inline -finline-functions -mcpu=power5+ -ftemplate-depth-100 -O0 -I/usr/local/myfft/bin/boost-1.35 -I/home/qa/mysvntop/femtown/applications -I/home/qa/mysvntop/femtown/modules -D_THREAD_SAFE -DBOOST_UBLAS_INLINE=inline -DBOOST_UBLAS_ENABLE_PROXY_SHORTCUTS -DBOOST_LIB_DIAGNOSTIC -DBOOST_ALL_NO_LIB -DNDEBUG -DFFT_BUILDSYSTEM_GENERATOR -I/usr/lpp/ppe.poe/include -I/usr/lpp/ppe.poe/include -DIBMGCC -c main.cpp -o /home/qa/MG/dotop/femtown/products/foo/release/main.o g++ /home/qa/MG/dotop/femtown/products/foo/release/main.o -lboost_filesystem -lboost_system -lfake_mpi_fake_mpi -pthread -g -maix64 -lm -lc -L/usr/vac/lib -lxlopt -lxl -mcpu=power5+ -Wl,-bmaxdata:0xFFFFFFFFFF/dsa -Wl,-b64 -L/home/qa/MG/actrantop//actran_current/libs -L/home/qa/MG/actrantop//actran_current/foo/lib -lstdc++ -lgcc_s -o ./bin/foo ========== foo [end] ========== I ran my binary through dbx in order to explore the core file.
