New comment by kruceter on void-packages repository https://github.com/void-linux/void-packages/pull/40347#issuecomment-1308081350 Comment: I managed to build grass 7.8.7 with proj 9.1.0. Its GUI started without any surprises; and what is more important, it works with python 3 (at least I swapped out everything related to python 2). That was my original purpose for picking this package, so I am content. vtk 9.1.0 is not tested yet; it is quite a large piece of software to build on my machine. @ar-jan, I have pushed all changes to the "proj" branch in kruceter/void-packages, so you can use them however you wish. --- @nezos > Grass GUI never worked Thank you for mentioning this. I was a little afraid to think that I broke grass by tampering with it in a related pull request. As for versions starting from 8, I had learned of incompatibility with the current wxPython4 through trial and error; this includes that issue you have referred to. Unless wxPython4 is updated, nothing can be done about upgrading to grass 8.
