!
I'm starting assembler programming. I have read all FAQs,docs & txt
about this, but I don't know why this program not works:

/* Program asmvar.cc: this program puts 10 in myvar */
#include <stdio.h>
main()
{char myvar =0;
__asm__ __volatile__ ("movb $10,_myvar"
        	      :
      	              :
      	              :"memory");
printf("i=%d\n",myvar);
}

I compile it with:
	gcc -O2 -o asmvar.exe asmvar.cc

But, the result is: 
	In function main
		undefined reference to "_myvar"

Help me, please!
