Please see the step by step in the document attached/linked. The same one you highlighted on. I source this script just before invoking the compiler. Which means the CC parameters are passed in as shown. Unless if you are suggesting that doing a "source" of the environment script is not enough? If so, then I would not be able to invoke the correct compiler as the PATH to it is setup by the same environment script I source. -Ad. > > > > > > > > Here is the version of gcc set up by the environment above: > > > > > > +++++++++++++++++++++++++++++++++OUTPUT > > +++++++++++++++++++++++++++++++++++++ > > > > aseema@en4078926linux:~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$ arm-poky-linux-gnueabi-gcc -v > > > > Using built-in specs. > > > > COLLECT_GCC=arm-poky-linux-gnueabi-gcc > > > > COLLECT_LTO_WRAPPER=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.1/lto-wrapper > > > > Target: arm-poky-linux-gnueabi > > > > Configured > > with: /home/aseema/myyocto/fsl-community-bsp/build/tmp/work-shared/gcc-4.9.1-r0/gcc-4.9.1/configure --build=x86_64-linux --host=x86_64-pokysdk-linux --target=arm-poky-linux-gnueabi --prefix=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr --exec_prefix=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr --bindir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi --sbindir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi --libexecdir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi --datadir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/share --sysconfdir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/etc --sharedstatedir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/com --localstatedir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/var --libdir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/arm-poky-linux-gnueabi --includedir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/include --oldincludedir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/include --infodir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/share/info --mandir=/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/share/man --disable-silent-rules --disable-dependency-tracking --with-libtool-sysroot=/home/aseema/myyocto/fsl-community-bsp/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux --with-gnu-ld --enable-shared --enable-languages=c,c++ --enable-threads=posix --enable-multilib --enable-c99 --enable-long-long --enable-symvers=gnu --enable-libstdcxx-pch --program-prefix=arm-poky-linux-gnueabi- --without-local-prefix --enable-target-optspace --enable-lto --enable-libssp --disable-bootstrap --disable-libmudflap --with-system-zlib --with-linker-hash-style=gnu --enable-linker-build-id --with-ppl=no --with-cloog=no --enable-checking=release --enable-cheaders=c_global --with-gxx-include-dir=/opt/poky/1.7.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/c++/4.9.1 --with-build-time-tools=/home/aseema/myyocto/fsl-community-bsp/build/tmp/sysroots/x86_64-linux/usr/arm-poky-linux-gnueabi/bin --with-sysroot=/opt/poky/1.7.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi --with-build-sysroot=/home/aseema/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual --enable-poison-system-directories --with-mpfr=/home/aseema/myyocto/fsl-community-bsp/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux --with-mpc=/home/aseema/myyocto/fsl-community-bsp/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux --enable-nls --with-arch=armv7-a > > > > Thread model: posix > > > > gcc version 4.9.1 (GCC) > > > > aseema@en4078926linux :~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$ > > > > +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > > > > > > Now trying to compile the simple “Hello World!” above I get: > > > > > > +++++++++++++++++++++++++++++++++OUTPUT > > +++++++++++++++++++++++++++++++++++++ > > > > aseema@en4078926linux:~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$ ls -l > > > > total 4 > > > > -rw-rw-r-- 1 aseema aseema 80 Mar 30 22:36 hello_arm_world.c > > > > aseema@en4078926linux:~/myyocto/fsl-community-bsp/build/tmp/sysroots/wandboard-dual/home/xuser$ arm-poky-linux-gnueabi-gcc hello_arm_world.c > > > > In file included > > from /opt/poky/1.7.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/features.h:389:0, > > > > from /opt/poky/1.7.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/stdio.h:27, > > > > from hello_arm_world.c:1: > > > > /opt/poky/1.7.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/gnu/stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory > > > > #
