Olen jonkin aikaa jo tehnyt C++-ohjelmaa jossa yksinkertaista SDL-grafiikka (vain viivoja, ympyröitä ja tekstiä (SFont)). Aikaisemmin kaikki sujui hyvin mutta yht'äkkiä SDL lakkasi toimimasta. Kokeilin jopa kääntää sen uudelleen mutta ei auttanut. SDL kääntyy hyvin, samoin ohjelmat kääntyvät mutta ajon aikana tulee virhe. Testiohjelma on:
#include <SDL.h>
int main(void)
{
if (SDL_Init(SDL_INIT_VIDEO) < 0) {
printf("ERROR at SDL_init: %s\n", SDL_GetError());
return 1;
}
SDL_Surface *screen;
screen = SDL_SetVideoMode(800,600,24,SDL_SWSURFACE|SDL_ANYFORMAT);
if (screen == NULL) {
printf("ERROR: screen init\n");
return 1;
}
return 0;
}
Eli jo inittiin tyssää. Virheeksi tulee:
ERROR at SDL_init: No available video device
Kääntörivi: g++ -Wall `sdl-config --cflags --libs` -o sdltest sdltest.cc
Käytännössä ei mielestäni ole siinä välissä tehnyt mitään radikaalia kun SDL lakkasi toimimasta. Asensin totem-xinen ja jotain jotta voin katsoa DVD-elokuvia Totem playerilla.
- Koneeni n. neljä vuotta vanha AMD Athlon 2500, näytönohjain Radeon 9600 Excalibur.
- Ubuntu 7.10
- SDL 1.2.12, SDL_image-1.2.6, SDL_mixer-1.2.8
SDL asennettu ensin kääntämällä sorsat (SDL, SDL_image, SDL_mixer). Toimi mukavasti kunnes lakkasi toimimasta. Sen jälkeen poistin ne make uninstall ja kokeilin uudelleen. Näiden jälkeen vielä kokeilin sudo apt-get install libsdl-dev
Onko jollain ideoita mikä mättää tai miten lähteä liikkeelle selvittämään asioita?
