Hi, those are "multiarch" packages, see: https://wiki.ubuntu.com/MultiarchSpec https://wiki.debian.org/Multiarch/HOWTO
There was already a libsdl1.2 Debian bug on this issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932372 Interestingly the libsdl1.2debian package *is* 'Multi-Arch: same', while the -dev packages is not. The same goes for libsdl2. According to this libsdl2 bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909740 the Multi-Arch support has been removed on purpose to avoid this other issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909778 I didn't dig deeper, but this is definitely more complicated than adding a Multi-Arch line to the d/control file. For updates in this issue I'd suggest you to follow the Debian bug #909740. ** Bug watch added: Debian Bug tracker #932372 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932372 ** Bug watch added: Debian Bug tracker #909740 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909740 ** Bug watch added: Debian Bug tracker #909778 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909778 ** Bug watch added: Debian Bug tracker #932372 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932372 ** Changed in: libsdl1.2 (Debian) Status: New => Unknown ** Changed in: libsdl1.2 (Debian) Remote watch: Debian Bug tracker #939666 => Debian Bug tracker #932372 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843126 Title: include files conflict with i386 version: split dev packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/1843126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
