Building unit_test with including linux file manually using created toolchain

[yaolinchang]

Hi All,

    We have install toolchain, but if we include <linux/xxx.h>", the result is error.

We have add -I path in compile as below: However, it still can't find linux path.

How can I do?

Test (1) => add -I git/include/linux

14.28-1.0.0/test/mxc_fb_test$ arm-poky-linux-gnueabi-gcc -mfloat-abi=hard -I /home/neo/fsl/build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git/include/linux mxc_fb_test.c -o mxc_fb_testIn file included from /opt/poky/1.7/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/stdio.h:33:0,
