Okay, I just did "git pbuilder update; git pbuilder login" to get into an unstable chroot, "apt install pstoedit" to install it, and ...
root@tarsk:/# pstoedit -help | egrep ppt pstoedit: version 3.70 / DLL interface 108 (built: Oct 11 2016 - release build - g++ 6.2.0 20161010 - 64-bit) : Copyright (C) 1993 - 2014 Wolfgang Glunz Default interpreter is /usr/bin/gs pptx: .pptx: PresentationML (PowerPoint) format (/usr/lib/x86_64-linux-gnu/pstoedit/libp2edrvpptx.so) root@tarsk:/# dpkg --status pstoedit | egrep Version: Version: 3.70-3 So, works for *me*! Perhaps you didn't install the corresponding version of the support library package? root@tarsk:/# dpkg --status libpstoedit0c2a | egrep Version: Version: 3.70-3 With the wrong library version the executable might not load the missing modules. In case this is the problem I've pushed (in the packaging repo) a strict version dependency to force the library version to precisely match that of the executable. Perhaps something less strict would be okay, but I don't feel like testing version-skewed configurations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1411907 Title: Missing build dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pstoedit/+bug/1411907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
