Hi Christophe, Yes, I just sent a new version with the package to the thread. The problem was Luis Felipe was able to compile it, probably because his system wasn't as up-to-date as yours. (That's why it worked in my computer too)
So I found the same error you found after doing a guix-pull. The new file I shared should work with the latest guix. As I explain in the previous message, the error was related with the update of some packages. More specifically with some graphics libraries and `vtk`, that changed its API in the 9.0.0 version and it doesn't work. Freecad is pretty tied to Debian-based machines so they use old-ish packages for development. It's not the first time we have issues with the packaging due to new versions not being compatible. > Sorry for the news... Software, mate. It is like that all the time. After all this time on the industry, I think I'm getting used to it :)
