clang C API version

Clang Frontend

Hi All,

I would like to build our software using both the clang 2.8 released API and
the clang 2.9 WIP API. I can do that by #including the appropriate header
file and setting a source-level pre-processor symbol to conditionally
compile for 2.8 or 2.9--this is what I currently do, but it's not too
pleasant for our build system.

I just wondered what the project's policy is on setting an API revision
number in a pre-processor symbol in the Index.h file for clients to query
and adapt their API use accordingly?

Thanks,

Hi Paul,

I think that this is a good idea. However, it should be done at the LLVM level (i.e. a llvm-c/Version.h file). I think that there is some support for this in the autoconfigury scripts, but I don't know its status. I'd suggest asking on llvmdev.
