makeindex stopped working

Hi everybody,

So I am working on a book project and for some time now the indexing stopped working. We’re not getting any error messages or anything else, the index files simply aren’t created (and so of course the index doesn’t appear in the pdf). The indexing never made any problems for a long time, just now that we’re working on the new volume we noticed it. Though I’ve already tested if it still works with older volumes and it doesn’t. There is only one PC where the indexing still works, and it’s running on older MikTeX packages. So we are assuming that it must have something to do with the new packages. Unfortunately I didn’t write the indexing code myself, somebody else did it long before my time. I attached it below. It is loaded to the preamble from an external document. Sadly I don’t know much about these things. I could imagine that you would have to change the code a bit for it to work again. Maybe someone of you knows the answer.


Cheers,
Marius
