compile gcc/g++ code with Sun CC shipped on Sun Studio 12 (linux)
Hola:
I have a large super multi-threaded program which compiles and works fine in FC5 (and up), I want to compile it with sun cc to see if it really runs faster and eventually being able to compile for Solaris to see if we can gain more execution speed (ultimately try it on a multi-core SPARC).
I have solved a few issues like different location for some includes (i.e. hash_map), also the fact the compiler complains about this not being correct:
class A {
private:
int p1;
public:
static const double UNSET= -9999999999999997.9999998;
}
But now I'm confronted with the issue that sun cc seems to not have "round(double)"
# man round
ROUND(3)Linux Programmer抯 ManualROUND(3)
NAME
round, roundf, roundl - round to nearest integer, away from zero
SYNOPSIS
#include <math.h>
double round(double x);
What should I do in this case ?
Is there a resource I can go and check of the general things I have to adjust to make a gcc -> sun cc port ?
Thanks.
