Hello,

ive now decided to use Mingw32 instead of MSVC.
I've compiled allegro, allegrogl, ode and installed the opegl libs and dlls all successfully.
I've downloaded the carterrain demo (sources) from http://benny.kramekweb.com.
during compiling i get following error message:
C:\MinGW\source\carterrain\src>make
gcc -c main.cpp -o main.o -O3
gcc -c glode.cpp -o glode.o -O3
gcc -c trig.cpp -o trig.o -O3

I think the error lies in this codelines:

#define DOUBLEBUFFER_BOX 10

};

Can anybody give me a tip ?

Thanks all for your great an fast support !

EDIT: read it again; and I think the problem is different from what I thought at first. Which line is line 92? I'm guessing it's
{ d_list_proc, 10, 40, 96, 48, 0, 0, 0, 0, 1, 0, resolution_lister },
in which case the solution would be to cast resolution_lister to (void *), like so:
{ d_list_proc, 10, 40, 96, 48, 0, 0, 0, 0, 1, 0, (void *)resolution_lister },
You may also want to change the (char *) to (void *), as void * is what is actually the datatype of the dp field in the dialog struct and implicit casts to (void *) are illegal in ISO C++.

Also, you may want to check the forum mockup tagsm, see the mockup is on link above the message box.

Whenever you get an error message like this, please mark the line indicated as the error (92 in this case).
Anyway, the solution is quite simple here. The dp member of the DIALOG struct is of type void*, not char*(*)(int, int*). This second type (in case you don't know) is a function pointer type, a pointer to a function with return type char* that takes one int and one int* argument. Cast the d_XXX to void* like this:

{(void*)d_shadow_box_proc, 0, 0, 320, 200, 0, 0, 0, 0, 0, 0, NULL },

This should compile just fine.

Oh, and please use code tags. Click "mockup is on" in case you don't know what these are.

Hi,
thanks for your help.
I've changed it to g++ and now the compiling works. But the created *.exe file creates an error. hmmm. the original *.exe file works.

hmm. I think the only one who can help me here is the coder of these demo ?

Or link with libstdc++.a (ie, inlude -lstdc++ on the command line).

What error?

EDIT: Tobias, maybe we should posting at the same time?

Tobias Dammers

Guess so.

You could give me a bit of detail on the error the exe creates. Does it crash on launch? Crash while running? Freeze? Reboot? GPF? Cause obscure behaviour in other apps / the os? If so, how? Throw error messages at you? If so, what are they? Can you manually shut down the exe (Alt-F4)? Kill it (via Ctrl-Alt-Del)?

And what's your system? compiler? allegro version?

Do the allegro examples compile & execute well?

Oh wait: Have you recompiled allegro and allegrogl? If not, please do so.

Maybe he felt homesick and built his own tropical version of the Hague over there?

Heinz,
Next time you post, can you:
Specify a more descriptive title
Use the mockup tags
Just list a few errors if there are lots all very similar
Say why it doesn't work or do what you expected.

Then it will be easier to help you!

Cheers
Pete

No, not homesick. I'm from Germany originally. But I could use a bit more Antillian weather over here right now...

Working on it... at least as far as music goes...
click here for aural sunshine: [URL http://www.home.deds.nl/~tdammers/audio/bilongo.mp3]
And before anyone starts nit-picking: Yes that song's from Cuba, yes Cuba is part of the Antilles, no Cuba is not part of the Netherlands Antilles.

Anyway, I could go and change it... but then it's kinda funny, so I'll leave it this way for a while...

Probably not. A while back, Matthew updated the timezone code and then everyone in the Netherlands was shifted to the Netherlands Antilles. Must have been the largest and fastest mass-emmigration ever.
Not sure if it affected others too though.

Well, I live close to the sea anyway, so might as well call it the Caribbean, and consider Frans Bauer a samba artist...
