I removed `IGALocateElement()` simply because it was broken. That happened long ago, and I do not remember the details by now. The needs I had at the time for `IGALocateElement()`...

What's the output of the following two commands? ``` echo $PETSC_DIR echo $PETSC_ARCH ``` Did you check the permissions of all the intermediate folders? I'm a bit clueless about what...

You did not tell me precisely what you were exactly doing. Originally, you told me you were doing "make all", but now you say "sudo make all". The problem is...

Sorry, totally my fault. As I'm not keeping a close watch on PetIGA, some changes in PETSc 3.18 broke things. I just pushed the required fixes. Please `git pull` your...

That’s the test regression I was talking about. Other tests are OK. I’m not sure when I’ll have time to debug the issue. I think you should be good to...

@hppritcha Wow... first time ever than all mpi4py spawn tests seems to work. @wenduwan Is this submod pointer update expected to land in branch v5.0.x?

@wenduwan An obvious problem is that Spawn is still broken for other reasons. Even if you add the label to run the spawn tests, I believe these will fail before...
