I was trying to install sage-4.8 from source in ubuntu 10.04. I had downloaded the sage-4.8.tar archive, created the sage-4.8 directory and then used the command "make". After nearly two hours, I got the report (only relevant part is shown below):

The result of uname -a is: Linux myname-desktop 2.6.32-39-generic #86-Ubuntu SMP Mon Feb 13 21:47:32 UTC 2012 i686 GNU/Linux Please suggest what I should do now. Will it be proper to use the "sudo make" command at this stage or should I do something about the already created sage-files and directories (in the failed installation process)? -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
