WSL Ubuntu: math.h: No such file or directory

[joaodfc]

Hello!

I decided to try WSL 2 with Ubuntu and install Geant4 v11, for practical reasons. I followed the Installation Guide - “Building and Installing from Source on Unix Platforms” and as far as I’m aware the installation was successful.

However, when I try to compile my project (via make command), I get the following error:

Scanning dependencies of target Microbeam
[  5%] Building CXX object CMakeFiles/Microbeam.dir/microbeam.cc.o

      |               ^~~~~~~~

I am not really sure what the problem is or if it is related to G4, but if anyone can help me, I would really appreciate it.

I have a VM with Zorin OS (which is based on Ubuntu 20.04.1) and everything works properly.

I have the WLS with Ubuntu 20.04.4 on Windows 11.
