Ok, thanks for the pointers! In fact, as I said, I have just used the usual ubuntu binaries from the sage server to make the live cd. I did this because I figured this could be a possibility to reduce the amount of work to have a working live CD considerably (given the fast release cycle of sage). And, as I said, it passed sage -testall without errors (exception: cython throws on error because there is no gcc installed in the base distribution). Also, as mentioned, the current ubuntu vmware image has exactly the same problem (i.e. plotting in R doesn't work, r.capabilities() give the same values). Also I have every header installed in my installation. There is a well tested development package, and I have even installed all the kernel headers . So I doubt it is really a problem of missing header files in the base OS. The same packages are used for all compiling purposes. I will compile a version of R and try to get it working, then I will compile sage from scratch an use it instead of the ubuntu binaries. Lets see where "the dog is burried" (german proverb). So is it right to say that plotting from R, and installation of most R- packages should work in a working sage install? Just to be sure it's no ghost I'm hunting ... emil -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
