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

Hi, monks

I am not able to install Goo::Canvas. Below are the steps I followed on my Ubuntu 12.10. I am new to Gtk and Perl Modules

perl -MCPAN -e shell
cpan>install Goo::Canvas

[download]

This produced below error:

MakeMaker FATAL: prerequisites not found.
    ExtUtils::Depends not installed
    ExtUtils::PkgConfig not installed

Please install these modules first and rerun 'perl Makefile.PL'.

[download]

so I tried 

cpan> install ExtUtils::Depends
cpan> install ExtUtils::PkgConfig

[download]

But again below error happened:

Result: PASS
  XAOC/ExtUtils-Depends-0.306.tar.gz
  /usr/bin/make test -- OK
Running make install
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!
ERROR: Can't create '/usr/local/man/man3'

+xtUtils/Install.pm line 494

Result: PASS
  XAOC/ExtUtils-PkgConfig-1.15.tar.gz
  /usr/bin/make test -- OK
Running make install

    It appears you are trying to update the system Perl by using CPAN. This is not recommended, as you run the risk of messing up system tasks which use Perl. If you want to use the system Perl, try to stick with installation from packages if possible. That would be the simplest but not the most flexible. 

    sudo apt-get install libgoo-canvas-perl

    Alternatively and probably better longterm but taking a little more work, you can install a second version of Perl into a separate directory (even a user directory without needing any root access) and update the new Perl all you want using CPAN without affecting the system Perl.

    As farang said, using apt-get with sudo is better on Ubuntu systems. Your prerequisite errors are probably due to not having the Gtk2 or Gtk3 libraries properly installed. The Perl Goo Canvas has various version levels, and at some point it switched to Gtk3.

    So, you probably need the Ubuntu Gtk3 c libraries and their associated header files( dev packages). The Goo Canvas c library needs a few associated Gtk3 libs like Glib, Cairo, etc. , and you normally would have to install them in a specific order; but apt-get with sudo should get the prerequisites for you on Ubuntu.

    I'm not really a human, but I play one on earth.

      @Anonymous Monk: Why am I getting permission denied error? I am the only user on this system, with admin rights. If I remember correctly I have installed, few modules before, like this, and never encountered permission denied problem.

      @farang: Thanks, I never knew, about installing perl modules, your way.

      Thanks, for looking into this, I could use Goo::Canvas in my Perl code now.

        Figure it out

        
mkdir '/usr/local/man/man3' or die Fudge();
use Errno;
sub Fudge {
  my @r;
  while( my($k,$v)=each %!){
    $v and push @r, $k
  }
  join qq/\n/,
    int($!).q/ /.$!,
    int($^E).q/ /.$^E,
    @r, q/ /
}
