Comment (by leif):
{{{
+ # On OS X 10.7 (Lion) or later, use clang as default C compiler
+ # as some older versions of XCode 4 ship broken versions of GCC
+ # which fail to bootstrap GCC-4.6.3.
}}}
Quoting William:
''I dropped this [Sage 5.0.beta13] on my OS X 10.7.x laptop, didn't type
anything special, typed "make ptestlong", and came back later to see "All
tests passed!". I.e., it built perfectly.''
''Note that I've upgraded both the OS and XCode to the latest released
version on this laptop. I think this is reasonable to require by anybody
building Sage from source on OS X 10.7, given that XCode is free.''
