Incompatible gcc/plugin versions

[exapsy]

When I try to make or dkms-install it says that there are incompatible gcc/plugin versions, specifically referring to structleak_plugin.so. The plugin seems to normally exist inside /usr/lib/modules/5.10.36-2-MANJARO/build/scripts/gcc-plugins but there seems to be a version mismatch?

Okay this was a fast one to solve, but good to keep logs of such issues. The issue is that I recently had a kernel update and haven't restarted the computer yet. I'm not sure about the exact problem specifically (maybe it used the new kernel's modules but it was still saying that it was the old kernel?).

But a restart solved the isuse!

Seems likely, a kernel update still sets up the different folders and build toolchains for the newer kernel (as far as I can tell), and as such can lead to issues such as the one you stumbled upon. Thanks for the report though, good to have at hand for future reference.
