setup.py fails to locate Windows DLLs

[Martijn Jasperse]

Thanks to the lack of naming conventions under windows, setup.py is unable to locate the latest precompiled DLLs from fftw.org which are of the form 'libfftw3-3.dll'. Yes, renaming is a fix but then I have duplicates as other programs look for this file structure.

So, a super-simple fix for this would to be to add something like to following after setup.py:29

            if os.name == 'nt' and lib is None:
                lib = util.find_library('lib'+name)
                if lib is None: lib = util.find_library('lib'+name+'-3')
            if lib is None: raise OSError, "File not found"

The last line is because when find_library fails it returns None instead of raising an exception. I believe this then works with the desired error handler.

I also suggest something like
   if packages == []: exit(1)
after check_libs() to stop it attempting to install 0 libraries...

Have been happily using pyFFTW3 under Linux for a while, and just trying to get it running under Windows for some less tech-savvy colleagues.

Cheers.

Hi,

which version of pyfftw are you using? This should be fixed in 0.2.1 already. Can you check?

Thanks

Err... you are absolutely right, I was using v0.2 obtained from berlios.de; had assumed the two sites were just mirrors but did not realise one was deprecated. My apologies.

Cheers.
