Hi Richard,
Ping ...
Hopefully you could recall sufficient context from this thread about
the 'include path for slang.h' cause compile error issue that we are
trying to fix here.
Bump.
I'm holding off on merging a kernel patch for this while this is still
outstanding.
Can I distill this into the following (in the hope of resolving it).
- do we want to fix this problem for all kernels, or just the linux-yocto
ones ? And by 'fix', I mean without the requirement of porting
a kernel patch to older recipes.
Cheers,
Bruce

linux-yocto-3.4: Disable extra slang header search path
Add in a workaround to avoid host infection detection build failures
from the slang include directory in perf. I'll defer to Bruce to
fix this properly but we need a workaround now as this is breaking
builds.

Since you mentioned 'workaround' in commit log, I would like to submit
another solution:
#1. Merge below kernel patch to kernel tree:

Subject: [PATCH] perf: add SLANG_INC for slang.h
Previously we hard code '-I/usr/include/slang' to CFLAGS to works with
some hosts that has /usr/include/slang/slang.h other than
/usr/include/slang.h like Fedora. This will cause compiling warnings
in some cases.
We'd better to provide user a chance to specify correct location of
slang.h then user could specify SLANG_INC to avoid compile warnings.
