[Numpy-discussion] Cross compile flags for tdm-gcc on mingw

2011-03-09 Thread Jonathan Wright
Hi folks, I was compiling some extensions for 32-bit python 2.5 on windows using a 64 bit gcc compiler (4.5.1). After a bit of head scratching it seems that I needed to patch numpy/distutils/mingw32ccompiler.py to add the following flags around where it says "set_executables": -m32 -static-libgc

This one comes up in a Java puzzler, but applies equally to numpy. http://www.youtube.com/watch?v=wDN_EYUvUq0 >>> import numpy, sys >>> abs(numpy.array([-sys.maxint-1],numpy.int)) > 0 array([False], dtype=bool) >>> abs(numpy.array([-129,-128,-127],numpy.int8)) > 0 array([ True, False, True],
