in reply to Is it possible to use modules without installing them?

In general, if the module concerned is a "pure perl" module, there is nothing (provided you take the copyrights etc with it) of including it into your script as source.

However, many modules have XS and/or C components and they obviously won't work without their compiled bits.

I'm not familiar with the internals of GD so don't know which is the case for it.

Being a graphics module, it's quite likely that at least some of it has been optomised to C for speed?

Well It's better than the Abottoire, but Yorkshire!

    Thanks for the reply!

    Unfortunately you've provided me with another question now, specifically for GD and for any other module generically, is there a way to find out if a module is "pure Perl"?

    I guess I could just go and look through the source code but I'm still pretty much a novice at Perl so I might skip parts I don't understand and not recognize them as being XS or C components. Maybe there is a module on CPAN that analyzes a given file to determine if it's pure Perl or not?

    Many thanks for any help and the help so far :)
      You can tell if a module is pure Perl or not by examining the dslip information.

      One module which does this is CPANPLUS (it also does a whole lot more, including module installation without root access, which I recommend over including the module source in your program*). The default shell includes the 'l' command which will give information, including the language used. might also give dslip info, but I don't know it well enough to say if it does or not.

      GD is C and Perl and a C compiler is needed. If your ISP allows you to use a compiler, you should still be able to install it without being root.

      [1] For instructions on how to do this with CPANPLUS, refer to the FAQ (available on the website).
