Okay, I tried the gcc -v -O -o <file><file.c> and get this output with
this little test program, PLEASE HELP!!!!(pout)
----------------PROGRAM---------------
/*User "gli" is a c programmer. He tried the following simple test program
that is designed to calculate x raised to the power y. */
#include </usr1/local/lib/gcc-lib/sun4/2.4.5/include/math.h>
main()
{
double x = 10.0, y = 0.0;
do {
printf("%f", pow(x,y));
y++;
} while(y < 11);
}
/* This is what he types on the command line where "power.c" is the named of
the source code file:
gcc power.c -o power
This is the error message:
ld: Undefined symbol
_pow
collect: ld returned 2 exit status
It looks like it can't find the math library. Do you know what the
problem might be? I haven't done any looking around. Thought I'd ask you
first. Thanks.
