Just to summarize some arguments... AGAINST supporting GCC 3.4.x: [ ] it increases the work by Minh and I [ ] we do not have any computers with gcc 3.4 right now, so would have to install gcc 3.4 on them. [ ] we rarely get requests from people who want to build sage with 3.4 (it happened once in the last two months) [ ] the new configure script that David Kirkby wrote requires gcc 4.x [ ] Robert Miller broke 3.4 support by introducing the ratpoints spkg in May, and it seems nobody has been motivated to do anything about this. FOR supporting 3.4.x: [ ] It probably would be easy at this point, since it just means fixing ratpoints. [ ] This reminds me of when we dumped support for Cygwin in 2007. In retrospect allowing that was a big mistake which I regret, because it has made getting support for Cygwin back vastly more difficult (in fact, so far impossible, since nobody has done it). [ ] There is a general principal that compiling code on a wider range of compilers is generally a good thing. [ ] Some users have non-admin access only on boxes that only have pre 4.x gcc's. -- William --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
