Hey there,

I was going to use irrnet for my networking in my game engine, i just love this irr* based tech, but ive come across a few linking problems

have i not installed irrnet properly into my project, ive included the header and linked the library.

Code: Select all

and here is the source

Code: Select all

sry no idea dude:(

one thing you can check
have you the same settings in your proj and in irrnetlite at
project settings -> c/c++ -> code generation -> runtime lib?

are same libraries ignored?
