[sage-support] Re: Arch Linux and Sage
I installed libfplll from the AUR, and copied it from the system. The libfplll build stopped while building "generate.Tpo", although gc1plus still consumed CPU time. I do not know why this was the case. As for the Singular thing, I have absolutely no idea. I'm on x86_64 Core 2 Duo E4500 2.2Ghz with 4GB RAM right now. Perhaps I'll try reformatting my system sometime to see if it's a problem with the libraries on my system. - Tim Joseph Dumol http://timdumol.com On Sun, Nov 8, 2009 at 1:06 PM, William Stein wrote: > > On Sat, Nov 7, 2009 at 8:58 PM, Tim Joseph Dumol wrote: > > The main issues are: > > > > * Incompatible libreadline.so.6 -- the libreadline in Sage is dynamically > > linked to libtermcap.

[sage-support] Re: Arch Linux and Sage
I've been building Sage on 32-bit Archlinux for at least one year now. With 4.2, I only have two problems: the sqlite issue and the R issue. Thanks to previous threads on this sort of thing, I work around them by copying the system libreadline.so and libgcc.so to the appropriate places in the sage build directory. It's a bit annoying because as far as I can tell I have to wait for sqlite to fail before copying libreadline, and then for R to fail before copying libgcc. So the whole thing needs a bit too much of my attention. On the other hand, after that I have sage-4.2-goodness with longtests passing. There are no problems with Singular on my system.

[sage-support] Re: Arch Linux and Sage
The main issues are: * Incompatible libreadline.so.6 -- the libreadline in Sage is dynamically linked to libtermcap. Arch Linux disables libtermcap, so one needs to copy the system's libreadline to $SAGE_ROOT/local/lib. This is also the case in binary distributions. * Issue building R -- this is a problem in many platforms with up-to-date GCC packages, and is worked around by either copying the system's libgcc, or by building Sage with the environment vars SAGE_FORTRAN and SAGE_FORTRAN_LIB set to the system's gfortran and libgfortran.so. * Build hangs while building libfplll, which is worked around by copying the system's libfplll, and editing the $SAGE_ROOT/local/installed/ to make the build system think that libfplll is installed. * Finally, after the build is done, starting Sage or running the doctests fails with a message about a function in the Singular interface not being implemented. I do not know any workarounds to this. Thus, it would probably be best to use the binary distribution for now. - Tim Joseph Dumol http://timdumol.com On Sun, Nov 8, 2009 at 12:39 PM, Josh wrote: > > Is there a reason why it does not compile well? > > On Nov 7, 8:54 pm, Tim Joseph Dumol wrote: > > Hey Josh, > > > > Currently, Sage does not build properly in Arch Linux.

In addition to what William said, I think we ought to eventually support pgf (either through matplotlib or on our own). This would be very handy in sagetex, for example. Note that we already use pgf to draw graphs (vertex/line things) in latex. There has been interest in a pgf backend to matplotlib (what we use to actually draw 2d graphics most of the time): http://www.mailinglistarchive.com/html/matplotlib-us...@lists.sourceforge.net/2009-08/msg00358.html I played with making a pgf backend to matplotlib once, but ran out of time to experiment with it.
