Sometimes it helps to clean the build directory and start from scratch. I never use package managers in emacs and do things manually, but if I were you I would {{rm -rf /tmp/irony}}, remove the package from emacs (if that is possible) and just start all over again.

Failing that, you can install things manually.

It's weird, the ClangConfig.cmake is installed, but not the LLVMConfig? Although the former depends on the latter. What is your distribution? It could be a packaging issue, installing an unusable ClangConfig.cmake. Maybe you need to install something like libllvm-devel? Also, what is the version of Clang?

sorry for the late answer internet blockage at our country. I use fedora an I just updated to Fedora 30. before that things worked fine but after a system upgrade this happened. It may not be an irony specific issue but it seems to be the only thing affected by (showing this) behaviour

Hi @yilkalargaw,

Would you please confirm if v1.4.0 with Fedora 30 + regular updates and bugfixes [edit: is affected]?

Thanks, Nicholas
