Ghostscript might not fully _generate_ but only _adapt_ PostScript data, e.g. e.g. identify and (re)wrap EPS and TrueType objects that might be broken internally. > Do you think it is possible to imagine a backport? The newest version > of ghostscript (in testing) is working even on armel. Debian might officially fix this issue, and release to stretch the same as now with a minimal patch. Obviously that requires figuring out what the actual cause of the issue is, and produce a working patch. You might try "backporting" as you suggest - i.e. recompiling a newer package in a buster or stretch environment. You might try persuade someone in Debian to issue a semi-official backport at https://backports.debian.org/ A 3rd option (or 4th, depending on how you count) is to try grab an intermediary release that might work with buster or stretch, from https://snapshot.debian.org/ - doing that and reporting back here which versions work and which doesn't would also be helpful in narrowing down what might be the cause for the issue. > My hardware is quite exotic and only Debian stable is supported (for > kernel).

If you are comfortable using irc, you might try ask questions about build environment in the #packaging channel on OFTC.net Kind regards, - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
