I’ve applied all (?) your patches and used the LyX made of it to export to ePub: support/Systemcall.cpp (291): Systemcall: 'python scripts/docbook2epub.py "java" "Intro.xml" "Intro.epub"' finished with exit code 2 Error: Die Datei kann nicht konvertiert werden ---------------------------------------- Bei der Ausführung von python $$s/scripts/docbook2epub.py "java" "Intro.xml" "Intro.epub" ist ein Fehler aufgetreten Can you please be more precise what to try? Ideally I can run some commands in terminal to diagnose the ePub export tool chain. I don’t like to run them from LyX at first.
