socket programming

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

Hi, I am trying to "use Socket" in my code. But I am getting this error:

Can't load 'C:/strawberry/perl/site/lib/auto/Socket/Socket.dll' for module Socket: load_file:%1 is not a valid Win32 application at C:/strawberry/perl/site/lib/ line 70.
at C:/strawberry/perl/site/lib/ line 859.
Compilation failed in require at line 3. BEGIN failed--compilation aborted at line 3.

My code:

use strict; use warnings; use Socket; my $protocol = getprotobyname("tcp"); print $protocol; socket(my $socket, PF_INET, SOCK_STREAM, $protocol);

How can I fix this?

    The perl code that you provided runs with no complaints on my machine.

    This is perl 5, version 24, subversion 0 (v5.24.0) built for MSWin32-x86-multi-thread-64int

    If I try to install the Socket module, I am told:

    Socket is up to date (2.021).

    If I look in C:\Strawberry\perl\lib\auto\Socket\, I see:


    Upon further research, I find that the Socket module is in the list of Perl core modules.

      yes, I have installed the v5.24 too. At C:\strawberry\perl\site\lib\auto\Socket I see the following files: .packlist,, Socket.dll, I don't see Socket.xs.dll. Is there anything I am missing?

        .packlist,, Socket.dll, I don't see Socket.xs.dll

        The files you're seeing are not from Strawberry 5.24. They are part of a much older version.
        ".bs" files are no longer installed, and Strawberry now builds ".xs.dll" files instead of ".dll".

        Your problem will go away if you remove that Socket installation (in its entirety) from perl/site/lib.
        That will enable perl/lib/ (which shipped with Strawberry) to be loaded - and all should work fine.

        However, it's likely that there are other extensions from the older perl present in perl/site/lib.
        Removing everything from the perl/site/lib folder is a valid option.
        That folder is normally empty when perl is installed - the only modules that go into it are the ones that you subsequently install (or, as in your case, the files that were there from a previous installation :-)

    Which version of strawberryperl are you running, which file did you download?
