fireblood has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I am trying to add LWP::Curl to my library of installed CPAN modules. When I initiate the process to fetch it and process it into my library, I see a message that says:
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
after which the process fails. I've downloaded curl both for Windows and for Cygwin directly from the source, https://curl.haxx.se/download.html, but have not seen the libcurl.pc file in either of them.
After doing much web searching, I've found that others have been encountering this since around 2008. However, I haven't found any posts that provide a solution.

    You've downloaded the Curl source - but you won't get a libcurl.pc (or an actual Curl library) until that source is compiled.
    One alternative is to install a Curl library that has already been built.
    UPDATE: Correcting myself, it's possible that this is what you've already done, but that the pc file is not provided.


    Unfortunately, huck's suggestion of (sudo apt-get install libcurl3-dev) is not going to help much on Windows and Cygwin.
    For Cygwin, there should already be such a library available for installation using setup.exe.

    For Windows (Active Perl and Strawberry Perl) you can install the LWP-Curl-0.14 module via PPM: 
    ppm install http://www.sisyphusion.tk/ppm/LWP-Curl.ppd --force

    [download]
    URI is a prerequisite. If you don't have that module installed you can install it with either: 
    cpan -i URI
or
ppm install http://www.sisyphusion.tk/ppm/URI.ppd --force

    [download]
    Installing with PPM means that you don't have to bother installing the Curl library.
    LWP::Curl PPM packages for perl-5.26 have not yet been built and uploaded, but I can rectify that fairly smartly if necessary.

    If you really want to build the module yourself, start with installing the Curl library, and set the PKG_CONFIG_PATH environment variable to the location of libcurl.pc.
    And get back to us with any issues that arise.

    Cheers,
    Rob
