GROMACS version: gromacs-2022.4/  
GROMACS modification: No

Here is the error recieved at the end of the compilation of the gromacs produced by MAKE:

Alternatively I’ve tried to install Gromacs using apt-get but it installed the version 2020.1 which have a bug in the xpm2ps utility.

How could I resolve my issue ? Are there any possibilities to update from 2020.1 to any versions that fixed the xpm2ps on the ubuntu 20.4?

Many thanks in advance  
Enrico

Hi! Have you tried using the solution from [Regarding the error undefined reference to `srot_', `strsm\_'](https://gromacs.bioexcel.eu/t/regarding-the-error-undefined-reference-to-srot-strsm/3910)? For Ubuntu, the analogous command would be `sudo apt install libblas-dev liblapack-dev`
