When trying to package libobjcryst, it became obvious that a SONAME had to be applied to cctbx, just as libobjcryst itself needs to patch in a SONAME. It is an extra amount of work but C++ symbols based on a package using lots of templates are fuzzy at best and with so many different modules in cctbx, the only practical way to handle it seems to be a new SONAME each time. The header files are also problematic. We might be able to restrict SONAME changes to upstream versions which make changes to the header files included in libcctbx-dev rather than every new upstream release. Until we've got cctbx through NEW, it is going to be hard to tell. > On a separate thread, I managed to package reduce [2] locally. > However, as you have also noted it, the name of source, binary and > executable is problematic.

Maybe package it as pdb-reduce or pdb-hydrogen-reduce ? /usr/bin/reduce does not exist in Debian yet but it may be worth packaging the script as pdb-reduce with a note in README.Debian - anyone switching from using the upstream build to Debian packages will need to make other changes anyway. > > [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679905#98 > [2] https://github.com/rlabduke/reduce > > Best, > Andrius > > -- Neil Williams ============= https://linux.codehelp.co.uk/
