No idea why 10.7 would be different. $ export CC=clang $ python setup.py build_ext -i Ralf ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

As is mentioned earlier in the thread, Xcode doesn't distribute plain gcc anymore. I've tried building with llvm-gcc, and with clang, and I get the same failed result. To be sure, I tried building with a plain "python setup.py install", and I get the same result.

You've successfully compiled both numpy and scipy in a couple of different ways on Lion, so you'll probably do a much better job there than I could. It's a wiki page, so you should be able to edit it directly. Thanks, Ralf ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
Re: [Numpy-discussion] Problem Building Numpy with Python 2.7.1 and OS X 10.7.3
Hi The plain gcc (non-llvm) is no longer there, if you install Lion and directly Xcode 4.3. Only, if you have the old Xcode 4.2 or lower, then you may have a non-llvm gcc. For Xcode 4.3, I recommend installing the "Command Line Tools for Xcode" from the preferences of Xcode. Then you'll have the unix tools and compilers for building software. The solution is to compile numpy and scipy with clang. I had no problems so far but I think few people actually compiled it with clang. The issue #1500 (scipy) may help here. http://projects.scipy.org/scipy/ticket/1500 On 25.02.2012, at 14:14, Ralf Gommers wrote: > Since you're using pip, I assume that gcc-4.2 is llvm-gcc.

As a first step, I suggest using plain gcc and not using pip (so just "python setup.py install").
