undefined reference to `___ashrsi3'

I get the linker error


  
	
	

		
		

			undefined reference to `___ashrsi3'


when compiling any code involving sprites. I've narrowed down specifically what code causes the problem:


  
	
	

		
		

			static void set_sprite(PICTURE *pcptr) {

	TEXTURE *txptr;

 

    	txptr = tex_spr + pcptr->texno;



    	slDMACopy((void *)pcptr->pcsrc,

        	(void *)(SpriteVRAM + ((txptr->CGadr) << 3)),

        	(Uint32)((txptr->Hsize * txptr->Vsize * 4) >> (pcptr->cmode)));

}


When I comment out this code, the error goes away. However, then I can't see any sprites.

Looking on Google, there seems to be some link with the math library (libm.a). I try to link with the library with -lm, but that doesn't do anything. I also try to add #include and that doesn't help either. I'm wondering if maybe ashrsi3 is in an older version of libraries.

Does anyone have any idea?

Haha. Solved again. The SGL "made-for-Unix" is incomplete. I used DosBox to compile with the regular SGL and it worked fine. Off to making some stuffs.

Thanks for pointing that out. I will check it out. Would make it super easy if I could compile everything from withing linux.
