Hi,
I have started again, simply executing:
>python setup.py install
However, I now get the following:
>File "numpy/core/setup.py", line 253, in check_mathlib
> raise EnvironmentError("math library missing; rerun "
>EnvironmentError: math library missing; rerun setup.py after setting the
>MATHLIB
>env variable
I have a math library from cygwin (libm.a).
How should I set this?
Thank you,
Olivia
