Power Render 2.6 (and 3) and C++

Recommended Posts

Hi !!

I tried to use C++ (Visual C++ 6) with Power Render. I
used an example and changed the names from .c
to .cpp !! Visual C recognizes that and compiles in
C++. At the beginning I got a lot of errors (for
example winutil.cpp, Direct X, you have to remove
these ->lpVtbl-> stuff). Also, everywhere you find
something like extern HWND hWndMain you will have
to replace that to extern "C" HWND hWndMain, and so
on, if not, you get Linker errors.
Now, after all these problems were found and
removed, I have a last problem, and I think it's a "bug"
in Power Render. When compiling I get the following
errors:

pr.lib(Prhrdwre.obj) : error LNK2001:
Nichtaufgeloestes externes Symbol _hWndMain
pr.lib(Prerror.obj) : error LNK2001: Nichtaufgeloestes
externes Symbol _hWndMain
pr.lib(Prglobal.obj) : error LNK2001:
Nichtaufgeloestes externes Symbol _hWndMain
..\game\gokart.exe : fatal error LNK1120: 1
unaufgeloeste externe Verweise
Fehler beim Ausführen von link.exe.

Sorry, it is german, but you can see it at the
ErrorCode. It means, that the linker could not find
hWndMain. The same errors came up before I put a
extern "C" instead of extern in front of external
variables and functions. Because these errors are
embedded into pr.lib, I cannot do anything against it.

Any ideas ????

Thanks.

Phillip

Yes, i have the same problem before.

This is how i bypass it.

I actually keep winutil.c as it is, but all my programs
are in .cpp

To get the value of hWndMain, i wrote a function in
winutil.c to return the value.
