Ich habe nun einiges ueber libsdl gelesen und finde alles sehr inter-
essant, hoert sich sehr vernuenftig an. Zudem wuerde mir es die SDL
ermoeglichen, schonmal ein bisschen rumzuspielen, obwohl ich erst ins
Programmieren einsteige. Daher wollte ich nun also mein erstes ("das"
erste sdl-Programm - das eigentlich "noch nix" macht) kompilieren -
doch wenn das funktioniert haette, wuerde ich dies hier wohl nicht
tippen! Im folgenden mein Leidensweg - ich hoffe auf einen freundlich-
en Fingerzeig von jemandem
debian(woddy) oder knoppix(3.1, eine japanische pre-version)
Das Programm sdltst.c:
include <stdlib.h>
#include "SDL.h"
// was ist der Unterschied zu <SDL.h>?
// beides versucht - error gleich
int main(int argc, char *argv[])
{
SDL_Surface *screen;
if(SDL_Init(SDL_INIT_VIDEO) == -1)
{
printf("Can't init SDL: %s
", SDL_GetError());
exit(1);
}
atexit(SDL_Quit);
screen = SDL_SetVideoMode(640, 480, 16, SDL_HWSURFACE);
if(screen == NULL)
{
printf("Can't set video mode: %s
", SDL_GetError());
exit(1);
}
SDL_Delay(3000);
return 0;
}
Beim Kompilieren folgender Fehler:
#gcc sdltst.c
sdltst.c:2: SDL.h: No such file or directory
Nun gut, der ist leicht (wenn auch nicht schoen), denke ich mir
und...
1) linke /usr/include/SDL/SDL.h nach /usr/include/SDL.h ...
#gcc sdltst.c
In file included from sdltst.c:2:
/usr/include/SDL.h:33: SDL_main.h: No such file or directory

/usr/include/SDL.h:47: begin_code.h: No such file or directory
/usr/include/SDL.h:95: close_code.h: No such file or directory
2) wenn das so ist, lieber den Pfad in Zeile 2 des Programms mit
angeben...
#include "SDL/SDL.h" ...
#gcc sdltst.c
/tmp/ccq8zGpa.o: In function `main':
/tmp/ccq8zGpa.o(.text+0xc): undefined reference to `SDL_Init'

collect2: ld returned 1 exit status
3) ...oder doch nicht! Dafuer lieber alle 29 in /usr/include/SDL
befindlichen Header nach /usr/include gelinkt - ich bin ja nicht
bloed _lol_ - und nochmal...

Da ich mir nicht vorstellen kann (vorsichtige untertreibung), dass es
unter debian unmoeglich ist, ein SDL-Programm zu schreiben, muss es
wohl an mir liegen
Bitte schenkt mir das kleine Stueck Wissen, das hier noetig ist
Vielen Dank
