We have another small problem with Lion. I just wiped my hard drive and reinstalled Lion (because of some non-Sage related issues). Then I reinstalled Xcode: the newly released version 4.3. Two issues: command-line tools are no longer installed by default, so you have to install gcc, clang, etc., by running Xcode, choosing "Preferences", clicking the "Downloads" tab, and installing "Command Line Tools". Next, there is now no longer a /Developer directory, which means that the command xcodebuild (which is run by the prereq script) may fail to report the correct version of Xcode. So from the shell, you need to run
$ xcode-select -switch /Applications/Xcode.app/Contents/Developer (and you may need to run this via sudo). So these instructions need to be added to the installation guide or the README.txt file. For the second issue, it might instead be better to figure out the version of Xcode some other way in the prereq script (and anywhere else this is done, like maybe the current python spkg). This version of Xcode has new versions of gcc and clang, so I'm trying to compile with those to see if it makes any difference. -- John -- 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
