Problem with Gmsh and Examples

Hey there,

I have the following error when trying to launch the GUI from pylith running in WSL.

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/ cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast

Do you have any advice on how to fix this?

Many thanks,

Gmsh relies on some system libraries for the GUI. It looks like you are missing some graphics libraries used by Gmsh in your Windows Subsytem for Linux (WSL).

Do you have the libgl1-mesa-dri package installed in WSL? The library that Gmsh can’t find could also be in a place that it is not looking (seems unlikely but a web search suggests other people running GUIs under WSL have this problem).

Hi Brad,

Yes I have the package installed, I can see it’s location in my folders:

Is there a way to change where Gmsh searches for it?

I doubt a file in /usr/share/doc is a library. Usually, libraries are under /usr/lib or /usr/lib64 Did you look at the contents of that file? There is a chance that file includes instructions for how to install the library.
