[Pawn] Run time error 19: "File or function is not found"

[Kwarde]

You can put this into your gamemode somewhere:

Code:

native WP_Hash(buffer[], len, const str[]); //This is a Whirlpool function, we will need that to store the passwords.

This should be enough, I don't include Whirlpool in my gamemode just the plugin, and works fine.

That's already in his script. That's why he's getting the runtime errors.
Native functions are pretty much ignored by the compiler. They do get loaded into the memory (prefix, natives section) and the server looks for those functions/modules. When they're then not found, it results in RTE 19.
If he didn't have this native function defined (yet used by the script) the script wouldn't compile.

(Not so) long story short: Make sure the plugin is loaded (as was mentioned before)
