Subject: [PATCH 27/47] 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.
