[Bf-committers] MinGW OSL compilation: Failure, steps taken so far

Hi, after a lot of effort I will quit trying to build Open Shading
Language for MinGW-w64, at least until a new LLVM version comes out
that better supports MinGW-w64.
I got to the point where I could configure OSL and build a few files.
The critical issue currently is that llvm-3.1 crashes when attempting
to work on OSL and llvm-3.0 can't parse some standard c headers of
MinGW-w64 properly. So I am stuck. I tried building LLVM with
different toolsets (configure/make explicitly supports setting a 64bit
target, which might have been the cause of the crashes. However, this
build fails (sometimes with a crash)).
However, I will post here the patches I've used so far in case anyone
else wants to resume where I've failed.
llvm-3.1 can be compiled straight from source with cmake on MSYS. You
will need python 2.7 and flex. m4 and bison for MSYS. Use cmake with
MSYS Makefiles generator instead of command prompt with MinGW
makefiles generator because this produces llvm-config, which is needed
for OSL (can be bypassed by fiddling with OSL cmakefiles but for my
own attempt I didn't do this). For llvm-3.0 you will also need ruby.
For llvm-3.0 you need to substitute the ${LLVM_CONFIG} lines on OSL
CMakeFiles with "ruby ${LLVM_CONFIG}". As explained though, llvm 3.0
can't parse MinGW headers right (some atomic operation definitions are
missing)
For OSL I've used this configuration:
-------------------------------------------------
make BUILDARCH=x86_64-w64-mingw32 OPENIMAGEIOHOME=/c/src/oiio-install
ILMBASE_HOME=/c/src/lib/mingw64/openexr BOOST_HOME=/c/src/libopt/boost
OPENEXR_HOME=/c/src/lib/mingw64/openexr LLVM_DIRECTORY=/
USE_BOOST_WAVE=ON USE_TBB=OFF VERBOSE=ON BUILDSTATIC=ON LINKSTATIC=ON
BUILD_TESTING=OFF
And these modifications on the source:
