- Subject: [PATCH] export CPP
- The OE environment sets and exports CPP as being the target gcc. When
- building gcc-cross-canadian for a mingw targetted sdk, the following can be found
- in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:
- configure:3641: checking for _FILE_OFFSET_BITS value needed for large files
- configure:3666: gcc -c -isystem/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/include -O2 -pipe conftest.c >&5
- configure:3666: $? = 0
- configure:3698: result: no
- configure:3786: checking how to run the C preprocessor
- configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
- configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
- configure:3876: $? = 0
- Note this is a *build* target (in build-x86_64-linux) so it should be
- using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
- headers are very different, using the wrong cpp is a real problem. It is leaking
- into configure through the CPP variable. Ultimately this leads to build
- failures related to not being able to include a process.h file for pem-unix.c.
- The fix is to ensure we export a sane CPP value into the build
- environment when using build targets. We could define a CPP_FOR_BUILD value which may be
- the version which needs to be upstreamed but for now, this fix is good enough to
- avoid the problem.
