[Numpy-discussion] Failure to build numpy 1.6.1

This looks like a compiler bug (gcc 3.4 is really old). einsum uses SSE intrinsics, and old gcc implementations are quite buggy in that area. Could you try the following, at line 38, to add the following: #define EINSUM_USE_SSE1 0 #define EINSUM_USE_SSE2 0 I meant to add this in the file numpy/core/src/multiarray/einsum.c.src, and then rebuild numpy David ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

That's more of a workaround than a fix. We need to decide whether we disable intrinsics altogether or wether we want to drop support for old compilers. cheers, David ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
Re: [Numpy-discussion] Cross-Compiling Numpy for NAO

Now I am trying to implement the same controller to a different robot, NAO - http://www.aldebaran-robotics.com/ This robot has a Linux based OS with Python 2.6.4. Since the goal is to implement the controller with the least changes possible and make sure the robot remains autonomous, it would be great to install numpy in it. The problem is that it is not possible to build numpy in the system and I was adviced to use the cross-compilation toolchain provided by Aldebaran. However, all their tutorials assume I can build the libraries I need with cmake, which isn't the case. Over on the cython-users list, I'm pretty sure someone recently contributed a cmake-based build for cython code -- maybe it could be leveraged for numpy? http://groups.google.com/group/cython-users/browse_thread/thread/c2aa7da05ae8df66 -Chris So, is it possible to cross-compile numpy, given a cross-toolchain, with not much effort? The other option is to use openCV, which comes with the NAO OS, but it require quite a few changes in the program... I tried searching the archives, but was unable to find any relevant post. I hope you can help me!
