load modules that are not part of the perl dist

[Petterson Mikael]

Hi,

I am new to perl.
I am a user of a perl script on solaris.( perl 5.6.1)
Since we are switching to linux we need to run the script with linux
perl (5.6.1). When I try to run the script on linux I get:

use: Command not found
use: Command not found
.......

The script contains:

# Standard includes
#---------------------------------
use Tk;
use strict;
use Tk::Balloon;
use Tk::BrowseEntry;
use Getopt::Long;
use IPC::ClearTool;
use lib "/vobs/rbs/sw/rbssw_tools/perllib";
use guiTools;
use deliverTools;
use ProgressBar;
use Label:esign;
use Label::Base;
use CC;
use SysAdmin qw(getRealName sendReport);
use Tk:LDialogBox;

use Text::Wrap;
use IO::Handle;
use File::Spec;
use File::Copy;
use File::Temp qw(tempfile);
use POSIX qw(strftime);
use FindBin;
use Trace;
use Tk::CheckEntry;
use Tk:LDialogMCListBox;
use Tk:LDialogListBox;
use lib "$FindBin::RealBin/plugin";
use PluginMgr;


Can I download these modules in a local directory
(/home/eraonel/perl-5.6.1) and refer to that in the script? ( I cannot
download the modules and install the in the correct directory
(/app/perl/5.6.1/lib/site_perl/5.6.1).

All hints appreciated.

Cheers,

//mikael

Try inserting a shebang line here:

Can I download these modules in a local directory

It's probably a shell compalining rather than perl.

Try inserting a shebang line here:

#! /usr/bin/perl

....

Or the OP can run the script using

$ perl script.plx

It's probably a shell compalining rather than perl.

Agreed.

 

[Petterson Mikael]

Try inserting a shebang line here:

#! /usr/bin/perl

I already have the path to perl at the top of myc script.

like this:

#!/app/perl/5.6.1/bin/perl -w

The FAQ assumes you are building your modules by hand. I think it should
also tell you (or point to someplace that does tell you) how to configure
CPAN so that it builds in a custom directory.

If memory serves, recent CPANs give PREFIX as an example when asking about
standard Makefile.PL options you might want to use for every module.

Well, how could we have known that if you chose not to tell us.

Your question is asked frequently, then. You should check the FAQ before
posting a question here:

perldoc -q lib

If you are going to use CPAN.pm for module management, see question 5 in

<URL:http://search.cpan.org/~andk/CPAN-1.76/lib/CPAN.pm#FAQ>

#! /usr/bin/perl

That blank is non-standard and looks dangerous to me.

That's not a Perl error message but probably comes from your shell.
You should investigate why the shell is trying to execute the script instead
of perl. Maybe your shebang line is missing or wrong?

BTW: Didn't today's FAQ posting address exactly this question?

remember how I did this, so I can't provided the language.

When you're first setting up CPAN, you need to NOT allow it to just go
ahead and use all the standard configuration answers. At one point, it
will ask you for arguments to the `perl Makefile.pl` command. At this
point, you need to specify whatever arguments you would give were you
building the module by hand (generally something like
`PREFIX=$HOME/lib`)

If CPAN is already configured, you can alter the configuration from
within the shell by typing
o conf makepl_arg PREFIX=$HOME/lib

If no one beats me to it, I'll figure it out again and write it down.

Well, I started typing before I saw any follow up of yours, so we'll
see which one arrives at various newsservers first.

Oh, and all this time, I have been making an effort to put a blank after
#! in my scripts

Gotta go fix 'em.

Thanks Anno!

Ah, yes this is bringing back memories. The main problem I had was in
getting CPAN to set up (as a non-root user) in the first place. The first
time I would get the following message:


: Your configuration suggests that CPAN.pm should use a working
: directory of
: /root/.cpan
: Unfortunately we could not create the lock file
: /root/.cpan/.lock
: due to permission problems.
:
: Please make sure that the configuration variable
: $CPAN::Config->{cpan_home}
: points to a directory where you can write a .lock file. You can set
: this variable in either
: /usr/lib/perl5/5.8.0/CPAN/Config.pm

I can't set this variable there. If I could set it there, I would be
root and therefore I wouldn't have had any permissions problems creating
the file /root/.cpan/.lock in the first place.

: or
: /home/xho/.cpan/CPAN/MyConfig.pm

I can't set it there either, because it doesn't yet exist. It would be
nice if cpan would offer to create a rudimentary copy of this file for me.

As it is, I figured out how to do it after reading a lot of documentation
and fiddling around a lot, then making ~/.cpan/CPAN, and copying the
Config.pm file from the location of `perldoc -l CPAN` into
~/.cpan/CPAN/MyConfig.pm. Then changing that file's
$CPAN::Config->{cpan_home} as suggested. Now CPAN will start, but it
thinks it is already configured (because MyConfig is a copy of an already
configured Config.pm, and not just a rudimentary config file). Read some
more documentation to figure out how to get it to forget about already
being configured.

It isn't all *that* hard for me to figure out and do this stuff, but of
course it would be easier not to have to. I don't want to sound
ungrateful, CPAN is a great tool, but it could be even greater (more
great?) if it were friendlier to non-root people. (But for all I know,
these things have been improved in versions after 5.8.0.)

Well, now that I've gone thoroughly off topic, I'll shut up.

Apparently a blank is more or less tolerated these days. Strictly it
would have to look for "usr/bin/perl" in the local directory " ". I
won't swear to it, but I think old unixes did this.

I think it must have been. I've setup CPAN.pm on a few non-root
accounts, and I can't ever remember going through the steps you just
listed...
