For osgcal I have search in the build log and found this error: "(EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so failed (/usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory)" I have also found that this file is provided by the libgl1-mesa-dri package.
Trying both depends and rdepends on apt-cache I have found (among with the help of ~d.filoni) the possible cause of the problem: # apt-cache depends libgl1-mesa-glx libgl1-mesa-glx <...> Conflicts: libgl1-mesa-dri Replaces: <libgl1> libgl1-mesa-glx libgl1-mesa-swx11 Replaces: libgl1-mesa-dri So I have tried adding the libgl1-mesa-dri package as build-dep in debian/control and the package was successfully built on my PPA: https://launchpad.net/~volans/+archive/+build/704939 I attach here the debdiff ** Attachment added: "osgcal_0.1.46-2.1ubuntu1.debdiff" http://launchpadlibrarian.net/17186188/osgcal_0.1.46-2.1ubuntu1.debdiff -- Packages need rebuild for libopenthreads6 -> libopenthreads7 and libopenscenegraph6 -> libopenscenegraph7 transitions. https://bugs.launchpad.net/bugs/263122 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
