Hello fellow programmers, I hope you are all doing well.

I have configured CMake with

Code: Select all

-DCMAKE_CXX_COMPILER=/usr/bin/clazy -DCMAKE_C_COMPILER=/usr/bin/clang

and running (c)make from konsole emit warnings just fine.

But I have trouble configuring clazy plugin inside KDevelop. I have installed =dev-util/clazy-1.8 on Gentoo but plugin's configuration can't find any check https://imgur.com/a/yxXYCV6.

Also right-clicking the project and selecting "Analyze with-> Clazy" is giving a whole lot of errors about "'stddef.h' file not found" because for some reason it still uses GCC.

Code: Select all

> make -j 1 -k -f /mnt/Volume_3/Gentoo/projects/CPlus/metal_calculator/build/kdevcompileanalyzerbHIUYv.makefile

I am lost here. I mention again that working with clazy/clang++ (=sys-devel/clang-11.0.0) from terminal works fine. So my questions are:

1.Why doesn't KDevelop detects all the other checks and levels or clazy?

2.Had any other user these troubles with "'stddef.h' file not found" and how did he/she solved them?

Thank you for your time.
