Anjuta Question

[grofaz]

I'm trying to build the SDL_Init example but I'm having difficulty with the library paths. Anjuta can't find the SDL library that defines the SDL_Init function. Can some knowledgeable Anjuta-nik please help me out ?? How do I set the correct library paths ? Appreciate any help! Thanks!

Do you have the correct dev packages?
Example: libsdl1.2-dev

[grofaz]

Yeah I loaded up all the SDL packages, but I don't seem to be able to set the library path correctly. Is it libSDL1.2-dev I need to link to? Thanks!

[grofaz]

Well, as far as I can see libsdl1.2-dev resides in /usr/share/docs but anjuta can't find it when I try a build. I've tried to set the library path accordingly but without success.

Where the heck is the file??

[DJ_Max]

This isn't an Anjuta problem. It's a problem with the example on your comuter. I'm gonna play around and see if I can get the SDL file to include.

[LordHunter317]

No, the shared library isn't there. It ought to be in /usr/lib, and all you should have to pass is -lSDL, I believe.

I don't know what led you to believe the library code is in a documentation directory.

[DJ_Max]

The file is /usr/include/SDL/SDL.h

What example are you using?

[grofaz]

The example from the dev-help docs. I #included <SDL.h> but it didn't recognize the SDL_Init function so I figured I'd better also set the library path to the SDL library file. I did set the include path correctly apparently since that part seems to work. I've been trying to set the libray path to every SDL library file I can find in /usr/lib and failing there anywhere else I can find that might have the correct file but when I try to build, it isn't found.

[grofaz]

OK...removing all references to sdl library paths this is what I'm getting:

And this is the program:

#include <SDL.h>
#include <iostream>

int main()
{
printf("Initializing SDL.\n");

//initialize defaults, video and audio
if((SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO)==-1))

{
printf("Could not initialize SDL: %s.\n", SDL_GetError());
exit(-1);
}

printf("SDL initialized.\n");

printf("Quiting SDL.\n");

//shutdown all systems
SDL_Quit();

printf("Quiting....\n");

exit(0);
}

HELP!! Thanks... :)

That's it! The correct library reference is: -lSDL

Thank you!!
