This compiles fine for me using extra/fltk, any reason to keep the AUR dependency?

Note that with the upgrade of the ntl package that just happened one must reinstall this package to get it to work correctly. The source code must be recompiled to use the new libntl

Nice! I'll update the PKGBUILD ASAP

After some discussion at trac.sagemath.org/ticket/12375, Bernard Parisse has started to release separately named source packages at http://www-fourier.ujf-grenoble.fr/~parisse/debian/dists/stable/main/source/ .

If you empty md5sum array, this will not check it and will avoid breaking the build when the delivery is updated without bumping the version.

I agree. However Bernard Parisse doesn't follow this versioning pattern. Bug fixes are made and new features introduced while keeping the same version number. The sources change at least every 2 days.

Zenol commented on 2013-09-23 20:30

Aren't they what version number are made for?

For example,

Major.Minor.Micro.Build

Can means :

Major -> Version name
Minor -> Breaking API changes
Micro -> Breaking ABI changes
Build -> Non breaking changes (bug fix)

When you install an aur packet, you expect (except when using -git packets) the version being always the same, given a packet name (that's why there are checksums).

That's very important because bug fix can also introduce new bugs, and some time you need to install the exact same version to many machines.

This is due to frequent fixes in giac for a given version. You can always bypass integrity checks if the PKGBUILD is not up-to-date.

The checksum seams to be broken :

I have a working PKGBUILD file for xcas version 1.0.0. I need to clean it up a little bit.

Calimero, could you submit it if I send it to you?
