hi folks!
sorry to bother...
my prob:
i just compiled the techdemo using devc++ (worked after upgrading from 4.0 to 5 beta, like suggested on the forum), i get no errors (just 2 warnings about "no new line at EOF" bla bla).
when i try to start the resulting exe, nothing happens...
then i run it from cmdline, and got following outpout:
Code: Select all
C:\irrdemo\demoproj\devcpp>techdemo
uncompress(): hello, hello!
gzread(): hello, hello!
gzgets() after gzseek: hello!
inflate(): hello, hello!
large_inflate(): OK
after inflateSync(): hello, hello!
inflate with dictionary: hello, hello!
i just imported the .dsp from irrlicht-0.6/examples/Techdemo, and added correct paths to libs and headerfiles.....
anybody knows some hint?
thanx in advance and greets,
---loki

Don't know if this is the problem cause its been a while since I've had that happen to me. But is the irrlicht.dll for the dev c++ in the system path or in the same folder as the executable. If I recall I got the same thing when I ran the executable without the dll in the path but then again I could also be wrong as it was a while go and my memory is shot to hell with all the caffine I intake.

so, still nothing happens...

plz help !!!

the fix is very simple, but I do not know exactly why it is required. Simply change WinMain to main. The aggravating thing is Dev-cpp can compile Windows applications using WinMain, but something about using WinMain with irrlciht Dev-cpp doesn't seem to like. It might have something to do with calling conventions. I believe that WINAPI is a typedef for _stdcall whereas the default calling convention is _cdecl. Perhaps the VC++ version of the enginecan use the _stdcall convention whilethe Dev-cpp version must use _cdecl. That last is just a guess, however, I'm really not sure.

Hey Guest, by any chance, could you post how you got your Dev C++ to compile? I followed the tutorials, but I still can't get it to work. Thanks for your help.

try the turtorial on setting up dev C++ it is pretty much work for word. Or if you are really lazy someone made a devpak(Or something like that) that has everything you need already set up for dev C++. do a search in the forum

Hmm, yeah had the same errors and the program produced a file foo.gz containing a text file which says hello, hello!,
