John M. Dlugosz has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to install Image::EXIF. Any idea what the problem is? When I issued nmake, I got linker errors for things that sound like they are part of the module. Here is the whole story:

[J:\temp\Image-EXIF-0.04\Image-EXIF-0.04]makefile.PL
Checking if your kit is complete...
Looks good
Have C:\Program Files\Languages\Perl\lib\Config.pm expected C:\PROGRA~
+1\LANGUA~1\Perl\lib\Config.pm
Your perl and your Config.pm seem to have different ideas about the ar
+chitecture
they are running on.
Perl thinks: [lib]
Config says: [MSWin32-x86-multi-thread]
This may or may not cause problems. Please check your installation of 
+perl if you
have problems building this extension.
Note (probably harmless): No library found for '-lexif'

Re: problem with a CPAN module

    Why did you issue make if nmake is your make program?(perl -V:make
    Did you see "Note (probably harmless): No library found for '-lexif'"?
    Do you have libexif? (the README lists it as a requirement)
    From what I can see, libexif does not yet come in win32 flavor. Have fun ;)

    Tutorials -> Writing, Installing, and Using Perl Modules -> A Practical Guide to Compiling C based Modules under ActiveState using Microsoft C++

    MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
    I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

      I saw that "possibly harmless" warning, but didn't understand it. I thought it had something to do with the way the module is packaged, not with a prerequisite.

      not yet a win32 flavor: ah, well, that's it then.

    At a quick glance there could be library problems. Maybe multiple copies of C libraries or such? I'm afraid I can't add much more than that.

    Cheers!

    Update: OK, so maybe on reflection, that didn't add much value. I hope other monks can be more enlightening.
