Hello everyone, I have been attempting to compile the entirety of boost on AIX 6.1 with gcc. Currently, I am compiling for 32-bits. I have had some moderate success by specifying extra flags to the compilation, but some issues persist that may require code change (or simply more explicit linking) and as a result I am at loss of what to do. Here are some of the issues that pop up: ld: 0711-317 ERROR: Undefined symbol: .test_main(int, char**) collect2: error: ld returned 8 exit status ld: 0711-317 ERROR: Undefined symbol: init_unit_test_suite(int, char**) collect2: error: ld returned 8 exit status I think these two are linking issues, but I am not sure how to include the missing files. The first primarily affects boost.asio, but others are affected as well. The second primarily affects boost.conversion. gcc.link ../bin.v2/libs/math/test/test_bessel_k.test/gcc-4.8.1/debug/link-static/test_bessel_k collect2: fatal error: ../bin.v2/libs/math/test/test_instances/gcc-4.8.1/debug/link-static/libtest_instances.a: not a COFF file In the math library I get this issue, and also many floating point constants are being truncated to zero. Is there any way to prevent that? Allocator = std::allocator<long unsigned int>] BOOST_MP_FORCEINLINE BOOST_CONSTEXPR cpp_int_backend() BOOST_NOEXCEPT{} ../boost/multiprecision/cpp_int.hpp:1032:41: note: candidate expects 0 arguments, 1 provided These compilation errors resolve around multiprecision. I don't know how to proceed on this error at all. I am currently compiling with the following command: ../b2 -a "cxxflags=-fpermissive -g" "linkflags=-lpthread -lc128 -Wl,-bbigtoc" Any suggestions or advice is appreciated! Thank you for your time! Sincerely, -Axel
