Problems installing mumu

Helloo I'd like to use mumu but I got problems with the installation:

git clone https://github.com/frederic-mahe/mumu.git

I'm using gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1) and GNU Make 4.3. No idea what is going on... could you guide me? Thank you.

Hello @CristinaZb

sorry, you need gcc version 10 or more recent to be able to compile mumu (I use this project as a benchmark to implement and test recent C++ features). It seems that your operating system is Ubuntu LTS 20.04. You would need to upgrade to Ubuntu LTS 22.04 to get a more recent version of GCC.

Alternatively, if singularity or apptainer is already installed on your operating system, I can provide you with a SIF file containing a working image of mumu (total size is 4 MB). You might want to try to install apptainer, but the process is quite complicated. I've just tried on a fresh Ubuntu LTS 20.04 virtual machine and it failed miserably.

Thank you for the comment Frederic. I've upgraded the OS to 22.04 to get the gcc version 11.2.0 and now mumu is installed correctly.

Thank you for trying mumu!
