[yocto] linux/limits.h: No such file or directory

[Takashi Matsuzawa]

Hello Yocto.

I am seeing this error recently, and wonder if it is a known issue that has a workaround.

It does not go even if I delete DL_DIR or SSTATE_CACHE, etc.  It started to happen, though previously the build ran well.

>configure: error: C preprocessor "x86_64-pokysdk-linux-gcc -E --sysroot=/mnt/ssd2/>yocto/dev/tmp/x86-wk3/sysroots/x86_64-nativesdk-pokysdk-linux " fails sanity check

If I look into config.log (gcc-4.9.2/build.x86_64-pokysdk-linux.x86_64-pokysdk-linux/libgcc/config.log) as suggested, I can see the following.
It says linux/limits.h is not found.

(in config.log)
>usr/include/bits/local_lim.h:38:26: fatal error: linux/limits.h: No such file or directory

I googled some, and found a few similar reports (e.g. install kernel headers first, could be a race condition, etc.) but I am not sure practically how to avoid this build break.

Error log (on bitable console):
