Description Eugene Zelenko 2019-03-28 01:18:03 UTC 
I think will be good idea to have possibility to output clazy-standalone command line argument used to build particular file to troubleshoot problems.

I built my project with Clang 8 and then tried to run clang-standalone using compile database. clazy-standalone complained about system headers:

/usr/include/limits.h:124:16: fatal error: 'limits.h' file not found
# include_next <limits.h>

Clazy was built with same Clang 8 as my own project.

See also https://github.com/include-what-you-use/include-what-you-use/issues/679 for similar problem.

clazy-standalone needs to be placed in the same folder as your clang executable.
Look for "stddef.h" in https://github.com/KDE/clazy/blob/master/README.md for other possible workarounds

Thank you for help! Workaround works for me.

Indeed! I mentioned your workaround already since it makes IWYU works too.
