Hi, the problem was that the stable versions until 6.6.36 just didn't build anymore. Therefore I uploaded the SVN package to the AUR btw ;-) I don't know if 6.6.38 build correctly, if you have a working PKGBUILD I think everyone would be happy (since it is stable). But I don't know if that is possible now since a higher version is already in the repos. That would mean everybody has to force a downgrade? I could help you writing the split package but I don't have much time this week. I can't assure you anything ;o) Sorry for being a bit off topic, but Jaroslav Lichtblau copied a bit from my PKGBUILD and left the configure option --optimize in the PKGBUILD. Does the current package work for you? Because --optimize breaks the standard makepkg CFLAGS ... Or is "-ffast-math -O3" considered safe for offical builds? Just to clarify myself, this is no offence I was just surprised to see the option. Best regards
