when I run this bash run_tests.sh，I get this error.

seems that is because #include_next "stdlib.h" but I don't know how to fix it . friend, have you met it before?

[qqiangwu]

can you provide more information about your environment?

it seems cppsafe failed to detect c include directories.

call the following and show me the result.

echo | g++ -E -xc++ -Wp,-v -

cppsafe <your-cpp-file> -- -v

if you have llvm installed, copy cppsafe to /opt/homebrew/opt/llvm/bin/ (maybe other directory in your machine) solves the problem too.

how weird it is ! it became normal when manually i use it.

seems that the problem still exists.

[SteveLee123]

finally, I fix it by

vim ~/.bashrc
export C_INCLUDE_PATH=/usr/local/lib/gcc/x86_64-pc-linux-gnu/11.4.0/../../../../include/c++/11.4.0
export CPLUS_INCLUDE_PATH=/usr/local/lib/gcc/x86_64-pc-linux-gnu/11.4.0/../../../../include/c++/11.4.0

source ~/.bashrc

[qqiangwu]

I'll investigate why the auto-detection failed.

[qqiangwu]

what's your os distribution?

[SteveLee123]

I'll investigate why the auto-detection failed.

the /usr/include should be the last one.

Maybe it is because when i upgraded my gcc, i was missing some steps.

[SteveLee123]

你的是什么操作系统分布?

suse

can I see your result of excuating this commands?

it seems so wired. and it causes so many false positive because it can not include the correct .h file.
