Sorry for the late answer.

This problem won’t be easy to solve, except if I go back to the previous situation, which was far from being ideal.

This is not a problem with tests. This is a building problem.

The issue is that Grammalecte needs itself to build itself. That’s why you already had an error previously, but it was non blocking because built elements were already provided within the sources.

I don’t think I have much choice to solve the situation. As a temporary solution, I will include anew these pre-built elements.
