installing WWW::Curl::Easy perl module in OS X 10.12.6

on Feb 08, 2018 at 00:07 UTC ( #1208666=perlquestion: print w/replies, xml ) Need Help??
igods has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to port some perl code over from my OS X 10.6.8 server to my new OS X 10.12.6 server. When I run the code, it trips over a missing WWW::Curl::Easy module:
------------------------------
[ns3:~/linkrabbit] administrator% ./linkrabbit.pl -s iq Can't locate WWW/Curl/Easy.pm in @INC (you may need to install the WWW +::Curl::Easy module) (@INC contains: /Users/administrator/perl5/perlb +rew/build/perl-5.24.0/ /Library/Perl/5.18/darwin-thread-multi-2level +/Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2le +vel /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.2/darwin-th +read-multi-2level /Library/Perl/Updates/5.18.2 /System/Library/Perl/5 +.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Libr +ary/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/ +Extras/5.18 . /usr/local/Cellar/curl/7.56.1/) at ./linkrabbit.pl line + 35. BEGIN failed--compilation aborted at ./linkrabbit.pl line 35. [ns3:~/linkrabbit] administrator%

------------------------------
Sure enough, WWW::Curl::Easy is not installed. So I pop over to cpanp to install the module, but fail miserably:

I have googled my brains out (and I google for a living), but haven't been able to get past this point for months. At this point, I'm quite lost. I'm hoping that I can reach out to someone who might better understand my predicament.

Can anyone assist?

My humble thanks.

Re: installing WWW::Curl::Easy perl module in OS X 10.12.6
by syphilis (Chancellor) on Feb 08, 2018 at 01:04 UTC
    /usr/include/AvailabilityInternal.h:22938:10: error: unterminated conditional directive

    The syntax of /usr/include/AvailabilityInternal.h is illegal, at least in the eyes of your C compiler.
    For every "#if" there needs to be a corresponding "#endif", and the C pre-processor hasn't found those requisite occurrences of "#endif". (All other errors are probably a consequence of this.)

    I suppose one could fix the offending file, but if you're using the system perl (as I suspect you are) then I believe that, instead of using cpan, it's recommended that you install modules using your system's package manager.
    /usr/include/AvailabilityInternal.h wouldn't even be looked at if you were to install WWW::Curl::Easy using the package manager.

    Update: See
    https://stackoverflow.com/questions/42031921/unterminated-unconditional-directive-error-when-preprocessing-c-code
    if you wish to persevere with a cpanp installation.

    Cheers,
    Rob
      Thank you Rob, I got further this time... I verified (and updated) curl and pkg_config in brew:
      ns3:linkrabbit administrator$ brew info curl curl: stable 7.58.0 (bottled), HEAD [keg-only] Get a file from an HTTP, HTTPS or FTP server https://curl.haxx.se/ /usr/local/Cellar/curl/7.51.0 (368 files, 2.6MB) Poured from bottle on 2016-11-21 at 15:29:25 /usr/local/Cellar/curl/7.56.1 (414 files, 3.0MB) Poured from bottle on 2017-11-08 at 11:37:40 /usr/local/Cellar/curl/7.58.0 (415 files, 3MB) Poured from bottle on 2018-02-09 at 10:38:12 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/cu +rl.rb ==> Dependencies Build: pkg-config ✔ Optional: openssl ✔, rtmpdump ✘, libssh2 ✘, c-are +s ✘, libmetalink ✘, nghttp2 ✘ ==> Options --with-c-ares Build with C-Ares async DNS support --with-gssapi Build with GSSAPI/Kerberos authentication support. --with-libmetalink Build with libmetalink support. --with-libssh2 Build with scp and sftp support --with-nghttp2 Build with HTTP/2 support (requires OpenSSL) --with-openssl Build with OpenSSL instead of Secure Transport --with-rtmpdump Build with RTMP support --HEAD Install HEAD version ==> Caveats This formula is keg-only, which means it was not symlinked into /usr/l +ocal, because macOS already provides this software and installing another ve +rsion in parallel can cause all kinds of trouble.

      I believe what I had missed was appending my .bash_profile to be able to find the brew installed curl:
      export PATH="/usr/local/opt/curl/bin:$PATH" export CURL_CONFIG=/usr/local/Cellar/curl/7.58.0/bin/curl-config
      I then attempted again to install the WWW::Curl::Easy module using cpanp... I now encounter different problems (so this is progress, yes?!)

      Rob, I'm not sure if I'm reading you right.. are you suggeting that I install WWW::Curl::Easy using brew? I'm not sure how to do that beyond:
      brew install curl

        I tried compiling WWW::Curl::Easy by hand, but came across the same errors:

        FYI, I checked my versions of curl and perl, and verified that they are the ones I expected:
