I think I introduced this error when moving a global variable from the
Cython module to a C++ module. The name collision with math.h was silent on
Linux, Mac, and Windows (MinGW and MSVC) -- or not even present --, and
thus went under the radar. But it eventually showed up on SunOS, and now
also on Cygwin. :-(

My apologies.

Anyhow, it should be gone now. Try SciPy master.

This looks like some Cygwin weirdness --- a variable called
"infinity" is apparently there declared by math.h, and thus
a reserved name.

This was fixed by (but not for this reason)
https://github.com/scipy/scipy/commit/832baa20f0b5
so you may have better luck with the dev version.

[Numpy-discussion] Compilation problems npy_float64

2015-11-05 Thread Johan 

Hello, I searched the forum, but couldn't find a post related to my 
problem.  I am installing scipy via pip in cygwin environment

pip install scipy

Note: numpy version 1.10.1 was installed with pip install -U numpy
