Arch Linux

When I revised our gcc package, I enabled the ada compiler, to find out the same thing you already found out: it needs an ada compiler to build, which we don't have on archlinux.
Any suggestion is welcome though.

Well, actually I managed to build custom gcc with ada enabled. I did this by using gcc binaries from other distribution (PLD as far as I can remember). I'll try to write PKGBUILD which do this.

Be sure to read the comments I added in the discussion tab, because the suggested compiler in the original article didn't work, at least for me.

Thanks Flavien, based on your tips I have finally written PKBUILDS for gcc and gnat.

The flow:
1. Build and install gnat-bootstrap package. It installs binary gnat 4.2.0 from Suse 9.2.
2. Build and install gcc with gnat support (PKBUILD-gcc_and_gnat). Now you can remove gnat-bootstrap package.
3. Build gcc (PKGBUILD-gcc) and gcc-gnat (PKGBUILD-gnat).
4. Install gcc and gcc-gnat packages.

I have updated PKGBUILDs for gcc 4.3.0

Hi, i tried to build gnat using these PKGBUILD's (i think there is an error on gcc_and_gnat updated for gcc 4.3 PKGBUILD), and i get an error on treelang. So, i remove treelang from enable-languages option, but i continue getting other error. I get this:

Aborting...

Yes, for some reason these packages doesn't work for gcc 4.3.0. I'll try to fix it but for now you can use my packages: http://michalm.ramtel.pl/gcc/gcc-4.3.0-2-i686.pkg.tar.gz http://michalm.ramtel.pl/gcc/gcc-gnat-4.3.0-1-i686.pkg.tar.gz

Thank you very much :)

i tried to compile from the previous PKGBUILDs, not including the old gcc-hash-style-both patch, but i got the same error. where can i find the patch?? please

dosent the patch found in /var/abs/core/devel/gcc/gcc-hash-style-both.patch work?

thanks Michał you saved my day! you should get a gold medal or something..

i'd prefer to see that pkg in AUR and not in the official Arch core repo. afaik nothing in the supported area would depend on it in the near future. so put it into AUR and wait for the usual voting process. maybe it will hit one day the community repo.

I'm not planning to add support for an ADA compiler to arch at this moment. Creating one needs a full bootstrap with weird binaries from other distributions. If I would create this package, I would install makepkg on a distribution like debian testing and build an ADA compiler with the gcc-gnat on that distribution and use the resulting arch-friendly package as bootstrap compiler for the final arch package instead of downloading some random RPM, extracting it and using that package.
