Problem during OpenModelica compilation

[nboldi@…]

I'm trying to follow the compilation tutorial found here: ​https://github.com/OpenModelica/OpenModelica

I installed the requirements, ran automake and the configure script. However, the make files are not generated.

I copied the contents of OpenModelica-commons to a folder named commons in the OpenModelica directory (otherwise files were missing).

Output:
