This will work for all newer FPC versions. This is the way Lazarus do it: Build-Depends: debhelper (>= 7), quilt, fpc, fpc-source, fp-utils, imagemagick > > Not necessary, only dev packages.

Unfortunately, we do not support multiple FPC versions in unstable, but only the latest upstream release. FPC team do a huge effort to keep backward compatibility and I rarely heard about new bugs due to a new version, but this still may happen, which is indeed probably your case. > Correct me if I'm wrong but I got the impression that software in debian > should > be rebuildable at all times, and having a transition period would greatly help > keeping stuff rebuildable. This is indeed the case with most SW using FPC: Changing the compiler do not affect SW. But still could have exceptions. The solution to your problem is to make upstream do an effort to reduce the amount of tricks that could be compiler specific. Cheers,
