Hi Karl, I would expect the Debian folks don’t want any libraries in there, pure-Perl or otherwise, that don’t work, and P:G:PGPLOT won’t without PGPLOT, which it seems they don’t want there.
As I tried to indicate before: I know as much as you do about how to make Debian etc packages. That was why I suggested sending them an email (presumably web-searching would also show up a tutorial). As far as I know, Ubuntu is a derivative of Debian, using largely the same packaging code and indeed package-wrappers, but rebuilt and released according to Canonical’s (who make Ubuntu) schedule rather than Debian’s, which is “stately”. You might even call Debian “stable” 😉 Best regards, Ed From: Karl Glazebrook<mailto:kglazebr...@swin.edu.au> Sent: 17 August 2021 02:32 To: Ed .<mailto:ej...@hotmail.com> Cc: pdl-devel@lists.sourceforge.net<mailto:pdl-devel@lists.sourceforge.net> Subject: Re: [Pdl-devel] Ubuntu/debian PDL packages & pgplot Hi all, Yes I can confirm that ‘pgplot5’ is real - I just checked it by building a fortran pgplot program in ubuntu. Thanks Ed, I missed that. Regarding the perl package, I suppose one could make two debs one which depended on pgplot5 (real) and one which depended on libpgplot0 (giza) and give users a choice? The debian people seemed politically determined against the real pgplot as a default when I last discussed this with them. So if I did that - I don’t know how to make debs or where to “register” or “upload” them? If there is an “idiots guide” that would be most welcome? That would explain things like what is the relationship between an ubuntu package and a debian one? Regarding the PDL::Graphics::PGPLOT, surely this can be put back in to the PDL deb? This would make things less complicated, it is after all a tiny pure perl package? Ed please let me know what you think about all these. Diab: - I agree Alien::PGPLOT might be a good way to go. Happy to help, I have some hard won expertise in building the library. Note I have been working with PGPLOT v5.3.1 that was never released! It has some macos improvements, what version is the autotools? - definitely you can draw a million lines in a blink with pgplot, no hope of doing that with matplotlib as a ‘line’ is a heavy object cheers Karl > On 17 Aug 2021, at 3:09 am, Ed . <ej...@hotmail.com> wrote: > > As far as I can tell, latest Debian/Ubuntu still has “real” PGPLOT in the > “pgplot5” package, so there’s no thought of “unofficial”. > > > > However, the current Ubuntu libpgplot-perl does depend on libpgplot0, the > Giza replacement, so you might want to update that to still depend on > “pgplot5” to make it the real, full-fat thing.
