Hi,
Firstly thanks to everyone that has helped bring NumPy to the point it is today. Its an excellent bit of software.
I've recently managed to get NumPy to compile on a 64 bit Solaris 10 (sparc) machine. We've embedded 64 bit Python in some of our C code using the Python C-API, and therefore require a 64 bit version of NumPy.
I had to use a bit of a hack to get NumPy to compile in 64 bit mode, and I'm just wondering if there's a more elegant way of doing it?
If I set CFLAGS to "-m64 -xcode=pic32", and CC to "/usr/bin/cc", it will raise the following error:
... snipped most of backtrace ... File "/home/leblanc/source/numpy/numpy/distutils/command/build_src.py", line 385, in generate_sources source = func(extension, build_dir) File "numpy/core/setup.py", line 675, in get_mathlib_info raise RuntimeError("Broken toolchain: cannot link a simple C program")
However, if I create a wrapper script and set CC to the path of the wrapper, then it will build normally and create a NumPy module I can use from the 64 bit version of Python installed on the system (/usr/bin/sparcv9/python). Here's the wrapper:
#!/bin/sh /usr/bin/cc -m64 -xcode=pic32 $*
I did a bit of googling and couldn't find much information on this issue (which is why I wanted to post this message, so others could find it). I'm satisfied with the results, but wondering if there's a better way to do it.
Cheers, Chris

Chris, I just repied to your post, thinking it was one I had made, since I did post on a very similar topic - building numpy on 64-bit Solaris! The solution which worked for me was CC="gcc -m64" export CC I guess if you use the Sun compiler, it will be CC="cc -m64" export CC Dave
