Hello,  
I am facing issues while trying to install CalculiX adapter in Ubuntu 18.04 LTS (WSL). The error displayed after running Makefile was

Hi,

Could you check whether `pkg-config` is installed? You could do that, e.g., with `apt list | grep pkg-config`. The package should show up with `[installed]` mentioned behind the package name. If the package is not installed, install it and see if it solves the problem.

Thank you for your response @ajaust . I checked the pkg-config and it is installed.

Hey @ajaust  
But if I run **pkg-config** in the terminal, it shows - Must specify package names on the command line.

I followed this [stack-overflow answer](https://stackoverflow.com/questions/35833574/pkg-config-command-not-found-during-compile-but-pkg-config-installed). It solved the problem and i could successfully install.
