No png produced

[blegat]

I tried the install instructions of the README. I'm running ArchLinux with the "libpng-1.6.37-3" package installed with pacman.
After following the README instructions, skipping the part for installing libpng since I already have it installed, I get

and no png is produced. Any idea what the issue might be ?
I tried

unset I_MPI_HYDRA_BOOTSTRAP
unset I_MPI_PMI_LIBRARY

as suggested in the README but it didn't help.

[dnelson86]

Is there any other output? Perhaps turn verbose = True in the parameter file. Likely there is an error coming from Arepo, rather than ArepoVTK.

Thanks for your reply, here is the output with verbose = true:

This

On node 'XPS15-arch-blegat', we have 1 MPI ranks and at most 0 MB available.

seems bad. This is coming from the report_comittable_memory function in arepo/system/utils.c, which tries to get information from the operating system about the node. If you run

cat /proc/meminfo

on this computer, does it have valid information?
