I am trying to build and compile the detail tests on AIX 6.1 with gcc, but there is one small problem on the very last test: gcc.compile.c+ + ../bin.v2/libs/detail/test/container_fwd/container_fwd_debug.test/gcc-4.8.1/debug/container_fwd_test.o In file included from /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.8.1/include/c+ +/cstddef:41:0, from ../boost/config/select_stdlib_config.hpp:18, from ../boost/config.hpp:44, from ../boost/detail/container_fwd.hpp:16, from ../libs/detail/test/container_fwd/container_fwd_test.cpp:6: /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.8.1/include/c+ +/powerpc-ibm-aix6.1.0.0/bits/c++config.h:277:4: error: #warning currently using inlined namespace mode which may fail without inlining due to lack of weak symbols [-Werror=cpp] # warning currently using inlined namespace mode which may fail \ ^ cc1plus: all warnings being treated as errors "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -pedantic -Werror -g -fPIC -fpermissive -g -ftemplate-depth-300 -pedantic -Wstrict-aliasing -fstrict-aliasing -Wextra -Wsign-promo -Wunused-parameter -Wconversion -DBOOST_ALL_NO_LIB=1 -D_GLIBCXX_DEBUG -D_STLP_DEBUG -I".." -c -o "../bin.v2/libs/detail/test/container_fwd/container_fwd_debug.test/gcc-4.8.1/debug/container_fwd_test.o" "../libs/detail/test/container_fwd/container_fwd_test.cpp" If I disable warnings being treated as errors through the Jamfile, the test functions correctly, but how do I customize the Jamfile file for AIX? Is it ok for me to simply ignore this warning? Also I was having a difficult time fully understanding what an inlined namespace is.
