[Numpy-discussion] FFTW and config vs system_info
Thu Aug 7 14:41:14 CDT 2008
That seems to have changed something for sure.
I created a modified site.cfg file. When I run system_info.py I get this
libraries fftw3 not found in c:\FFTW
libraries fftw3 not found in C:\Python25\lib
libraries fftw3 not found in C:\
libraries fftw3 not found in C:\Python25\libs
Library fftw3 was not found. Ignoring
libraries = ['libfftw3-3']
library_dirs = ['c:\\FFTW']
define_macros = [('SCIPY_FFTW3_H', None)]
include_dirs = ['c:\\FFTW']
Seems conflicted. Does this mean it is using FFTW? Is there any other way
to definitively check what scipy is using? I've benchmarked my FFTs before
and after this change and there is a difference (a slow down actually).
