[Boost-build] Boost context with IBM XL C/C++

Subject: [Boost-build] Boost context with IBM XL C/C++

Hi,
i am trying to build boost 1.55 with IBM XL C/C++ for AIX, V12.1.

1) As far as i understand, the context library must be build (even if --without-context), and the assembly code for PPC/XCOFF does not exist. Is that right ?
2) I encountered "invalid opcode or pseudo-op/Error In Syntax/Invalid relocation type: plt/..." because XLC do not understand ELF pseudocode. I am trying to patch 64bit/libs/context/build/Jamfile.v2" without succeded. Any hint for that?

Thanks for replies.

Tristan
