Just to let you know here (I need this for some R package but may be
this information is helpful for others as well).
I maintained the Debian package in the past:
https://tracker.debian.org/pkg/gpcl
It was removed from Debian in 2014. Should it be reintroduced ?
Finally you probably know the reasons for packaging it better than
me - but just license wise it should be possible now.
The gpcl package was in the non-free section in the past. I wrote it
mostly because I was needing a lightweight polygon clipping library. I
have also wrote Octave bindings for it.
There are other alternatives to GPC, though, like the kbool component of
WxArt2d [1], Clipper [2], and CGAL [3].
For the Debian package, I have added autoconf/automake/libtool support
for building a shared library for GPC. This improvement has never been
adopted by the upstream author. I might try to propose it as a merge
request to the new GitHub repository.[4]
I see that there is an R package that includes the GPC sources (gpclib
[5]). Is this package the one that you mentioned in your original
message?
Back in 2001, I decided to call the source package gpcl instead of gpc,
in order to avoid a name clash with another package (I guess it was the
Gnu Pascal compiler, but I am not sure). At any rate, there is no gpc
package in Debian, so if we rename gpcl to gpc, I think it will be fine.
I will try to fill an ITP for gpc, as time permits.
Best,
