Subject: [LTP] [PATCH] ltp: Fix cross-compile issue
Date: Tue, 16 Dec 2014 15:34:57 +0100	[thread overview]
Message-ID: <1418740497-24661-2-git-send-email-mats.liljegren@enea.com> (raw)
In-Reply-To: <1418740497-24661-1-git-send-email-mats.liljegren@enea.com>

Compilation included the flag "-I/usr/include/tirpc" which ignores sysroot.
This makes a cross-compile to suddenly use host files rather than the files
installed in the compiler sysroot.

By prepending path with "=", the "=" will be replaced with the sysroot path.

Example of error in a Yocto build of ltp:

arm-enea-linux-gnueabi-gcc  -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed --sysroot=/media/data/fb/mlil/yocto-builds/build-keystone-evm-nohzfull/tmp/sysroots/keystone-evm -O2 -pipe -g -feliminate-unused-debug-types -g -O2 -fno-strict-aliasing -pipe -Wall -W  -O2 -pipe -g -feliminate-unused-debug-types -Wold-style-definition -D_FORTIFY_SOURCE=2 -I/usr/include/tirpc -I/media/data/fb/mlil/yocto-builds/build-keystone-evm-nohzfull/tmp/work/armv7a-vfp-neon-enea-linux-gnueabi/ltp/20140508-r32/git/testcases/network/rpc/rpc-tirpc/tests_pack/lib -pthread -I../../../../../../../../include -I../../../../../../../../include -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed  -L/media/data/fb/mlil/yocto-builds/build-keystone-evm-nohzfull/tmp/work/armv7a-vfp-neon-enea-linux-gnueabi/ltp/20140508-r32/git/testcases/network/rpc/rpc-tirpc/tests_pack/lib -L../../../../../../../../lib  rpc_get_myaddress.c   -ltirpc -lrpc-tirpc -o rpc_get_myaddress
