Problem during linking

SDL Development
1

Hello,

My name is Smitha. I wanted to use SDL libraries to be able to create
graphics using gcc on cygwin.
I downloaded SDL-1.2.14. I have the source package and have already opened
the archive and installed the package.
I have a small piece of code using SDL with C to get me started with using
SDL. It is as shown below:

#include <stdio.h>
#include <SDL.h>
#define WIDTH 640
#define HEIGHT 480
#define DEPTH 32
*int main(int argc, char * argv[])
{
SDL_Surface screen;
SDL_Event event;

  • int keypress = 0;
    int h = 0;

if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
return 1;
}*

  • if(!(screen = SDL_SetVideoMode(WIDTH,HEIGHT,DEPTH,SDL_FULLSCREEN |
    SDL_HWSURFACE)))
    {
    SDL_Quit();
    return 1;
    }
    return 0;
    }*

I compiled and linked the code with the following command:

gcc sdl-config --cflags sdl-config --libs SDLTest.c

I get the following error:

/cygdrive/c/Users/smitha/AppData/Local/Temp/cc0XrJvy.o:SDLTest.c:(.text+0x4d):
undefined reference to '_SDL_SetVideoMode’
collect2: ld returned 1 exit status

output of command sdl-config --libs is:
-L/usr/local/lib -lmingw32 -lSDLmain -lSDL -mno-cygwin -mwindows
output of command sdl-config --cflags is:
-I/usr/local/include/SDL -I/usr/include/mingw -mno-cygwin -Dmain=SDL_main
Please help.

Regards,
Smitha.

Hi,

try
gcc sdl-config --cflags SDLTest.c sdl-config --libs
. The order of the libraries is important, the compiler will search for
symbols only in the following libraries in the call.
