File::ShareDir dependency not working

[devel-chm]

I tried to use cpan on a cygwin/win7 system and the Alien::FFTW3 failed to build because File::ShareDir was not installed. I didn't see it listed in the dependencies
in the Build.PL. Maybe that is why things did not work.

Thanks, Chris.

I'll check the File::ShareDir issue this morning and push up a fix if that's the issue.

I didn't work very hard on getting Alien::FFTW3 to work on Microsoft Windows simply because the FFTW3 site is so explicitly deprecatory toward trying to get their library working at all on that platform. If you have been able to compile a working libfftw3.a under Microsoft Windows.

Cheers,
Craig

Hmmm, I can't find the FIle::ShareDir dependency in a quick scan.

Although Build.PL does contain the following lines, that shouldn't apply to Cygwin. Does it install properly if you pre-install File::ShareDir? If so, we can run down the dependency and bug the right module author.

if($^O =~ m/MSWin/) {
die "Sorry, Alien::FFTW3 doesn't work for Microsoft Windows.\n\n Maybe someone will fix it for Microsoft syst
ems.\n\n Maybe that someone is you.";
}

cygwin is a unix perl, not windows. The win7 information is only in case there is some issue specific to the underlying windows version (usually not---unless the software gets confused in configuration and tries to treat the cygwin as windows and not unix).

There are actually prebuilt DLLs for FFTW as well as what appears to be pretty complete information on how to build a link library for the DLLs if you wish to use MSVC. See this page for the details: http://fftw.org/install/windows.html
