anjuta a SDL

[K.Urbánek]

Nazdar, snazim sa vytvorit program v anjute s pouzitim kniznice SDL. Bohuzel mi to nejak nejde a navzdory temu, ze pouzívam oficialny priklad z dokumentacie ke knihovne. Pravdepodobne teda neni problem v kode, ale v spusobu jak ten program nechavam zestrojit. Ale, kde?

Ten program je taký:

#include
#include

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);
}

A anjuta mi pise toto:

Tak to uz nevim - C/C++ neznam, neumim, nerozumim ...

[Krtko]

s sdl som este nerobil, ale podla tohto

main.o(.text+0x24): In function `main':

main.o(.text+0x67):/home/kudu/Projects/test2/src/main.cc:23: undefined reference to `SDL_Quit'niesu definovane tie SDL_*. nebude to nahodou este v nejakom inom SDL header? alebo ak to tam urcite je tak si to skus nadefinovat primo do tvojho zdrojaku. ja som raz mal taketo problemy problemy s time.h a stacilo to v podstate len prekopirovat priamo do toho mojho zdrojaku.

Nemas tam definovany parametry kompilatoru pro knihovnu sdl
musis tam pridat vystup

Kód: [Vybrat]

$ sdl-config --libs
$ sdl-config --cflagsJinak nevi kde ma tu knihovnu hledat..

[K.Urbánek]

Tak sem to vyriešil, problém byl v tem, že sem, nemnel nastaevené flags -lSDL v možnosťách kompilátora. Stačí do listu knižnice vpísat SDL a krásne to běží. Každopádne díki za snahu.
