Can't run SDL apps in OSX 10.6

Lagrange_Marc · December 8, 2010, 11:09am

Hi,

I’m trying to run a simple SDL test under OSX 10.6 but it fails, saying:

*** Terminating app due to uncaught exception
’NSInternalInconsistencyException’, reason: ‘Error (1002) creating
CGSWindow’
*** call stack here
terminate called after throwing an instance of ‘NSException’

The test code is the following:

… snip …
/*

Built with
cc -g -ggdb3 -fno-inline -o test_sdl test_sdl.c
-I/opt/local/include -L/opt/local/lib -lsdl -lsdlmain
*/
void run();

int main(int argc, char *argv[]) {
run();
}

#include <SDL/SDL.h>

void run()
{
SDL_Init(SDL_INIT_VIDEO);
SDL_SetVideoMode(640,480,0,SDL_OPENGL);
}
… snip …

Versions:

OSX 10.6.5
SDL 1.2.14 from MacPorts

Have I missed something ?

Thanks.

Might be because there is no surface linking to SDL_SetVideoMode(640,480,0,SDL_OPENGL);
add these two lines

SDL_Surface *screen;

screen = SDL_SetVideoMode(640,480,0,SDL_OPENGL);

Same problem.

This example works with SDL 1.3, but i need to use the 1.2.x :(On Fri, Dec 10, 2010 at 11:51 PM, image28 wrote:

Try the SDL.framework from the official binary DMG with the starter
Xcode projects from the dev-extras DMG. I haven’t seen your error. I
just tried the basic Xcode template project and the OpenGL Atlantis
template project and both worked fine for me under 10.6.5/1.2.14.

But i’m not using XCode here, XCode examples works but I don’t want to use it.On Sat, Dec 11, 2010 at 12:06 PM, Eric Wing wrote:

My apologies if the stuff below sounds stupid or ignorant but

… snip …
/*

Built with

cc -g -ggdb3 -fno-inline -o test_sdl test_sdl.c
-I/opt/local/include -L/opt/local/lib -lsdl -lsdlmain
*/
void run();

int main(int argc, char *argv[]) {
run();
}

#include <SDL/SDL.h>

void run()
{
SDL_Init(SDL_INIT_VIDEO);
SDL_SetVideoMode(640,480,0,SDL_OPENGL);
}
… snip …

main() enters, calls run() which initialises SDL then run() returns and
main() returns (without actually returning an exit code). The SDL event
loop never entered.

If some threads are started when SDL talks to OpenGL (don’t know if that
happens or not) which would need to be synchronised by the event loop,
that might be an issue.

Also, does SDL return any error code from either calls?
Do you know which one fails?

(Note that I have no idea what libsdlmain is, I only ever linked against
libsdl on Linux)

Seems to be an OSx specific thing.On Sat, Dec 11, 2010 at 1:52 PM, Zolt?n K?csi wrote:

#include <SDL/SDL.h>

I think the problem is that main is declared before SDL.h is included, you
should include SDL before main so that SDL substitutes main() with
SDL_main() and does it’s internal initializations. You should also link with
SDLmain.On Wed, Dec 8, 2010 at 12:09 PM, Lagrange Marc wrote:

sdl-config --cflags --libs is the recommended way, atleast on GCC.
Everyone loves a good one liner, especially if it works the same on
all systems.
SDL makes it so easy, programmers don’t even have to worry about cc parameters.On Sat, Dec 11, 2010 at 7:52 AM, Zolt?n K?csi wrote:
