Hi Jason, Qepcad sounds VERY interesting. I have not heard about it before. Do you know how to install qepcad (on a mac)? I did not find it in the optional packages list. Cheers Stan On Oct 25, 5:48 pm, Jason Grout <[EMAIL PROTECTED]> wrote: > The optional qepcad package can solve inequalitie

I just had another look around for qepcad on sage. Here is what I found: There is a ticket for including an interface to qepcad (http:// trac.sagemath.org/sage_trac/ticket/772), which has been merged in sage 3.1.2.alpha2. According to this ticket, it seems that qepcad does not compile properly on

Hi Jason, Thanks for that. Unfortunately, the compilation produced some errors. I put the log at ftp://ftp.bgc-jena.mpg.de/pub/outgoing/sschym/qepcad_errors. It starts with "Could not determine processor type" and "Could not determine OS type". Stan On Oct 27, 12:02 pm, Jason Grout <[EMAIL PROT

Thanks, but the comments on the install page do not sound too promising. Even if I finally managed to get qepad to work on my computer on its own, I wouldn't know how to make sage work with it, so I'll wait until someone more knowledgeable with osx and enough time solves the problem. Or until Sage

Yes, that's right, Mathematica does solve inequalities using the Reduce[] command. Forgot about that! If EQPCAD does what Reduce[] does in Mathematica it may be well worth the effort to get it installed. Thanks for the instructions. I may give it a try. I can't wait for the improved equation and i

Actually, the qepcad distro is only made for Linux and Solaris, so I suppose we would need to put more effort into getting it compiled on a mac. mksysdep.pl only tries to get the architecture of the computer in order to call the appropriate install script, but there is no install script for a Mac,
