Anyhow, help packaging I have a few "Suggests" in sagemath.spec for packages I added to non-free, but I packaged only what is required to run "sage -testall" plus a few extra optional packages, and run the optional tests as well. But I would not be surprised if there are some packages with not truly open source license, or unmet special conditions; but they are only available from "contrib" mirrors, and upstream tags them as GPL, BSD, etc, but I did not fool proof read every license... > the remaining components would be most welcome. Major problem should be integration of all components. There are few cases where it is required some patch to a package that is not only a sagemath requires. Most intrusive AFAIR are ntl patches. Some components really require a specific version, what may not be easy to achieve either, but so far, for Mandriva besides a PYTHONPATH with several patched components, for sagemath 4.8, most notably is use of a custom cython and ipython. Should work with current system cython, but that depends on the stage of the moon (if cython is updated) :-), there is only one binary in PYTHONPATH (cPickle.so) that I have been carrying for quite some time, http://bugs.python.org/issue7689 and generating it by doing a build of python in sagemath build. Sometimes some problems are very specific to the package, what may be hard to track, like this one http://code.google.com/p/gmpy/issues/detail?id=49 or some other earlier related issues with sympy having its own copy of mpmath, and then having conflicting modules loaded. > Regards, > -- > Jerry James > http://www.jamezone.org/ > -- > devel mailing list > devel@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/devel Paulo _______________________________________________ scitech mailing list scitech@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/scitech
