in thread problem with Math::GMP

How did you build your underlying GMP library. It looks like you have probably built/got a dynamic gmp.lib and tried to link against that. See this for an explanation of the difference between static and dynamic linking. But in essence you need to link to a static gmp.lib (which contains all the machine code) so that you can build a gmp.dll (for Perl) that can be dynamically loaded and has all the machine code (aka entry points) it needs.

If this is for Net::SSH::Perl it *may* be possible to simple s/Math::GMP/Math::BigInt/g as these modules are *almost* totally compatible.

Math::GMP was designed to be a drop-in replacement both for Math::BigInt and for regular integer arithmetic.

That may be an easier way to do it for you. If your SSH needs are modest there is plink.exe (google for Putty.exe) which gives you a command line ssh tool you might just be able to control through the shell.

    Yes this is for Net::SSH::Perl. I installed GMP::BigInt and replaced Math::GMP with Math::BigInt in all the modules. But still when I execute the following script

    use Net::SSH::Perl;

    $host="xxx.xxx.xxx.xxx";

    $username = "user";

    $pass = "pass";

    $ssh=Net::SSH::Perl->new($host, debug=>1, cipher=>'DES', port =>22);

    $ssh->login($username, $pass);

    my(@arra) = $ssh->cmd("?");

    print "output: $arra\n";

    I got this message with an error

    $ perl cisco_pix.pl

    Undefined subroutine &Math::GMP::sizeinbase_gmp called at /usr/lib/perl5/site_pe rl/5.8.2/Net/SSH/Perl/Util/RSA.pm line 30.



    I am using Cygwin bash shell.

    What is the compatible function for sizeinbase_gmp in BigInt?

    Regards
