[Numpy-discussion] Trouble building numpy on different version of OSX.

[Steve Spicklemire]

OK,,, I happen to have an old:

/Developer-3,2,5 directory on my 10.8 system, and I found the "xcode-select' command. I tried

sudo xcode-select --switch /Developer-3.2.5

but that had no apparent effect.

Next I put a link in

/Developer -> /Developer-3.2.5

since that seemed to be the path numpy was trying to use.

Aha! I got the right include path now. So there was an SDK effect somehow. I wonder if the 2.7.3 build on python.org used XCode 4 with a newer SDK? Anyway... still no luck though since I was getting complaints about stdarg.h not being found, even though I could see it was there. I noticed that

/usr/bin/gcc was really a link to llvm-gcc-4.2 and maybe that was a problem, so I changed my PATH environment variable to have

/Developer-3.2.5/usr/bin before /usr/bin and voila! It works. Thanks for the hints! Now just have to remember all this atrocious stuff whenever I need to rebuild it. ;-)

thanks,
-steve
