7ed1c190 - tools: fix cross-compile var clobbering

Wed, 21 Feb 2018 22:45:12 +0000

tools: fix cross-compile var clobberingCurrently a number of Makefiles break when used with toolchains thatpass extra flags in CC and other cross-compile related variables (suchas --sysroot).Thus we get this error when we use a toolchain that puts --sysroot inthe CC var: ~/src/linux/tools$ make iio [snip] iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory #include ^~~~~~~~~~This occurs because we clobber several env vars related tocross-compiling with lines like this: CC = $(CROSS_COMPILE)gccAlthough this will point to a valid cross-compiler, we lose any extraflags that might exist in the CC variable, which can break toolchainsthat rely on them (for example, those that use --sysroot).This easily shows up using a Yocto SDK: $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi $ echo $CC arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi $ echo $CROSS_COMPILE arm-poky-linux-gnueabi- $ echo ${CROSS_COMPILE}gcc krm-poky-linux-gnueabi-gccAlthough arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the--sysroot and other flags that enable us to find the right libraries tolink against, so we can't find unistd.h and other libraries and headers.Normally with the --sysroot flag we would find unistd.h in the sdkdirectory in the sysroot: $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h' [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.hThe perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is notalready set, and it compiles correctly with the above toolchain.So, generalize the logic that perf uses in the common Makefile andremove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile.Note that this patch does not fix cross-compile for all the tools (somehave other bugs), but it does fix it for all except usb and acpi, whichstill have other unrelated issues.I tested both with and without the patch on native and cross-build andthere appear to be no regressions.Link: http://lkml.kernel.org/r/20180107214028.23771-1-martin@martingkelly.comSigned-off-by: Martin Kelly Acked-by: Mark Brown Cc: Tejun Heo Cc: Li Zefan Cc: Johannes Weiner Cc: Linus Walleij Cc: "K.
