Perl Problems, pcap.pm

01-09-2005

When I try to run one of my perl applications I get this message:

Can't locate Net/Pcap.pm in @INC <@INC contains: c:/Perl/lib c:/Perl/site/lib .> at C:\Documents and Settings\Admin\Desktop\progs\pcap-getIV.pl line 27

Does someone know how to fix this?

First, what Perl do you have installed.

Second, have you installed the PCAP module? Check the code for any "use" statements. Make sure any module addressed in a "use" statement has been installed on your system.

I recommend ActivePerl, and use their Perl Package Manager (ppm) to handle all package installations.

Good luck!

It means that on line 27 of pcap-getIV.pl, there is a call to the PERL Module pcap.pm.

Either download and install the pcap.pm, or if you have done that, make sure the path is correct.

I tried finding pcap.pm, but I can't find it anywhere. Does anyone know where to get it?

for PPM, is there a GUI version? I run all my perl stuff through cygwin and the ppm with active perl won't run.

The reason why I run cygwin is that when I run perl.exe I never get the C:/, it is just blank. Someone had that problem?

Thanks for all the help!

ActiveState's ppm for ActivePerl will not run with cygwin. If you're using cygwin, go to cpan to find the necessary module, download it and build it under cygwin/perl.

It isn't a problem, per se. The EXE just doesn't know what to do, as you haven't given it an argument.

Simply run PERL from the command line with an argument like it was intended:

C:\> \perl\bin\perl myscriptname.pl

or:

C:\perl\bin> perl myscriptname.pl

I use ActivePerl as said previously. I've also used cygwin perl, but don't like it because you have to build/compile all the modules.

I put the perl\bin directory in my path, then I can run the files by just typing the scriptname.

c:\>script.pl

If you want ActivePerl to co-exist with cygwin Perl, I think it can be done. You can leave perl off your path, then have a couple .bat files to update your path for either version of Perl as desired.

I love ActivePerl because of the PPM. Further, they now have the pcap modules available directly. Check my perl sniffer pages for details.

It can certainly be done that way and it is certainly more elegant, but I using the KISS principle. I just figured that if Heinrich was having difficulty understanding why it wouldn't run without the arguement, then getting into setting default paths might be pushing the issue.

I have now found the pcap.pm and the program finds it. However, now it is asking for the module.

Picture

I downloaded pcap.pm from cpan, pcap.pm was the only file I got. How do I Build the module in cygwin?

Go back to cpan and find the readme. Then, RTFM. Another good site for perl support is PerlMonks

If you give me a link to the code I'll take a look at it, see if I can make it work for me.
