In fact, I don't know how to check this easily: it ships the same build of gcc as XCode 3 (3.2.6, to be precise) (gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)) and there is no ready way to check the version of the whole setup. The difference sits in libraries. One notable difference is that cc is not gcc, but a gcc-llvm build. (namely, gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.6))) So one can test that "cc -v" != "gcc -v", but this does nor seem to be robust enough. Probably one can use Applescript, but I have no clue about it. > > (2) if xcode 4 is being used (as detected by 1), the error message > should suggest xcode 3, and explain how to revert to it. (Is it easy > still?) To revert back, I tried xcode-select, and it didn't quite work, as Xcode 4 overwrites /usr/* with new stuff, and probably something didn't work as expected. I ended up re-installing XCode 3 in the usual way. (and then I removed XCode 4 to save space, so I can't easily check things any more :-( ) Dima > > -- William > > > So I reverted back to Xcode 3. > > (I should have added this to Wiki, but I lost my password, it > > seems :-)) > > > Dima > > > On Apr 28, 4:28 am, William Stein <wst...@gmail.com> wrote: > >> Hi, > > >> Aly Deines showed me what happened when she installed Xcode 4 then > >> built Sage.
