GPL Ghostscript PKGBUILD in AUR

Question

http://aur.archlinux.org/packages.php?d … s=0&SeB=nd
I've already uploaded it, although I should have checked with you folks first. Hussam was kind enough to guide me through its creation, though.
Please tell me if you see something out of place, or if the package doesn't work.
BTW, it should replace ghostscript package, but for some reason it fails to do so. The install would simply abort telling me the ghostscript is needed but this package and that package. I have included the provides, replaces, and conflicts lines, but that didn't work... Any thoughts?
Besides that, the PKGBUILD is a heavily modified version of the original ghostscript PKGBUILD, so there are some traces of the old package, which ultimately don't make a difference (or so I believe).
The reason why I needed this package is that ghostscript package (ESP Ghostscript) is
1. outdated compared to GPL
2. supposedly lacks features that GPL version has
3. depreciated by most Scribus users

I had a compile error with your PKGBUILD. I found out why. Apparently Ghostscript-GPL depends on gtk. There is a way to disable that, but I have a patch that updates the dependency to GTK2, well, because 2 is better than 1.
I don't know much about PKGBUILDs yet, but I managed to hack in the patches:
Heheh, I'm still green, too. But I'm new to the whole package building thing anyway, so you do have a nice head start right there.

ghostscript-afpl-8.54-gtk2.patch
ghostscript-afpl-8.54-segfault.patch)
I don't know much about patching. However, those patches seem to be for AFPL GS, which uses a different license...

Basically you
md5sum filename
and copy/append the output to
md5sums=('md5sum1 md5sum2 md5sum3...')
line. I think you need to supply those only for files listed under source=(...) line.

Very nice... but again, I don't know if those patches are supposed to be included in GPL Ghostscript.
SchaduwBlink wrote:The patches ... well, they can be found at those bug locations but I did a search and the Gentoo cvs had them all right there in on location, plus a few more that I don't know what they do. You may be interested in them. Also, you might want to click on the parent directory link and look at the ebuild, it has info on how to use the other patches, including one that adds support for a printer that I do not have. Also, the ebuild has the sed lines needed to disable support completely for GTK.
Uh... ebuilds are a bit over my head. At least at this moment. You see, I was not going to actually maintain the package. I just wanted to make a good working PKGBUILD and have it in AUR so others can take over if interested. I just needed GPL GS so I had no choice but to build it myself.
Yeah, I have GTK so I would have never thought to check for it. The Ghostscript docs mention no dependencies... at all

I think if pacman -Qs pkgname returns output, it means a person has pkgname package. So if there's a bash thing that can do such checks, you can know if the package is present. But I don't know how.

Anyways, the folder that has all the patches:
http://viewcvs.gentoo.org/viewcvs.py/ge … gpl/files/
These patches seem to work alright. It built. You may want to look in them and see if you would like to include them and if the pathes are correct.
Well, if it builds, I think it can be considered a quick and dirty working version of the PKGBUILD. Until proven it is also elegant and correct, that is. I'm just unsure about the licenses. As I said, I have no capacity to check the patches myself. But if you know what they do, and if they work, you may supply us with a working PKGBUILD, and I'll upload it... or you may upload it yourself. I don't know how AUR functions in such cases... i.e., if multiple users are allowed to submit fixes for a single package.
SchaduwBlink wrote:Cheers, and thanks again for your time on Ghostscript-GPL. I can't live without it.
No prob. Glad I saved one life with this package. If you want, you can take over the maintenance, since I don't know if I can manage it properly.
