I can't speak for anyone else (hence I can't really answer your question) but I have had problems compiling giac for amd64 hardy heron. I'm fairly impatient though, and maybe if I tried harder I could have gotten something to compile. I did spend maybe 30 minutes on it and gave up. I also tried installing it on an intel macbook but the package refused to install on my firewire drive. It's actually the first application I've run across which has refused to install on my firewire drive (my tiny HD is full:-). Is it possible to fix this? Can you create a system for which someone using amd64 hardy heron (a very popular distribution) can compile it from source (at least after a specific number of dependencies are installed using apt-get). In other words, can you create the analog of http://modular.math.washington.edu/sage/doc/inst/node5.html ? If so, I'd be happy to test it out. Also, is there any documentation in English? (I mean something more than a 5 page tutorial.) Sorry if I seem to hijack your thread. Actually, giac seems potentially interesting but it is difficult for me to say more. > By the way, I installed in ~parisse on sage the 64 bits binaries > version of giac (icas) and xcas so that everybody can test benchmarks. > Unfortunately a few system libraries on sage have bad rights, e.g. > libstdc++.so.6 is rw instead of rwx, hence one must run > export LD_LIBRARY_PATH=~parisse > before running > ~parisse/icas > For example > g:=(x+y+z+1)^20; h:=(x-y+2z-2)^20; time(r:=normal(g*h)); > time(factor(r)); > > > > --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
