Looks like you forgot your libraries. Here's a small Makefile example:

Code: Select all

CPP=g++
IRR=/YOURPATH/irr41
IRRLIBS=-L$(IRR)/lib/Linux/ -lz -ljpeg -lIrrlicht -L/usr/X11R6/lib -lGL -lXxf86vm -lXext -lX11 -lz -ljpeg -lIrrlicht
IRRINC=-I $(IRR)/include/
                                                                                     
example: main.cpp
        $(CPP)  $(IRRINC)  client.cpp -o $@ $(IRRLIBS)

[/code]

Thanks. I had to add -lpthread but it worked.

Now that I'm awake, I see a Makefile was included with the source...
