Hi Tristan,
The failure to build the context library does not necessarily prevent other
libraries from building.
If you are not specifically interested in using the context library, I
think you can remove references to it from the build or ignore the failure.
As for your workaround, is the command being used still referring to the
ELF assembly?

Sent by: "Boost-build" <boost-build-bounces_at_[hidden]>
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
