    weird errors gcc: functions like floor(), ceil(), sqrt()


    I just recently started working in linux red hat 9.0 to compile my C programs , I am using the gcc command but the program is giving me weird errors and does not recognize the functions ceil(), floor() and sqrt(), I have tried and added most header files like math.h nad stdlib.h along with stdio.h but I keep getting wried errors like :

    /tmp/ccqz1JFE.o(.text+0xba): In function `main':
    : undefined reference to `sqrt'
    collect2: ld returned 1 exit status

    The program is as follows

    int main()
    	double i, j, k;
    	for(j = 0.0; j < 1.0; j += 0.1)
    		printf("%8.1f", j);
    	for(i = 0.0; i < 10.0; i += 1.0)
    		for(j = 0.0; j < 1.0; j += 0.1)
    			k = i + j;
    			printf("%8.1f", sqrt(k));
    	return 0;

    Don't cross-post, it's rude. A lot of us read all of the forums, so cross-posting will likely be counter productive. Instead of getting you a faster response, we might just ignore you.
    My best code is written with the delete key.
