Hello, I am trying to compile boost on AIX 7.1 with gcc, but I am getting several errors. The configuration checks report that zlib support is disabled even though I do have that package installed. I also don't have icu support. Is there a package for that in AIX? I was not able to find one. Performing configuration checks - symlinks supported : yes - 32-bit : yes - arm : no - mips1 : no - power : yes - lockfree boost::atomic_flag : yes - has_icu builds : no warning: Graph library does not contain MPI-based parallel components. note: to enable them, add "using mpi ;" to your user-config.jam - zlib : no - iconv (libc) : no - iconv (separate) : yes - icu : no - icu (lib64) : no - x86 : no - gcc visibility : no - long double support : yes warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message. - zlib : no I also tried adding a user-config.jam in the boost/ (the same place as the project-config.jam) in order to add some flags to my gcc compilation and to use mpi, but my jam was soundly ignored. However, the most concerning of these errors is some apparent assembler error. gcc.compile.asm bin.v2/libs/context/build/gcc-4.8.1/release/link-static/threading-multi/asm/make_ ppc32_sysv_xcoff_gas.o Assembler: /tmp//cc0uhEhf.s: line 5: 1252-016 The specified opcode or pseudo-op is not valid.

I'm not sure how to go about fixing that. When I go to my /tmp/ directory ccvhH2Fc.s is not an assembler file present. Right after this message another error appears. ...failed gcc.compile.asm bin.v2/libs/context/build/gcc-4.8.1/release/link-static/threading-multi /asm/jump_ppc32_sysv_xcoff_gas.o... gcc.compile.c++ bin.v2/libs/context/build/gcc-4.8.1/release/link-static/threading-multi/untested. o libs/context/src/untested.cpp:7:2: error: #error "! code for this platform is untested - please r emove this file from build/Jamfile.v2 and report the test-result on boost-track !" #error "! code for this platform is untested - please remove this file from build/Jamfile.v2 and report the test-result on boost-track !" What is the complete path for the Jamfile.v2 that this error refers to? Any advice the community can offer would be greatly appreciated. Sincerely, -Axel
