Subject: [3.4/4.0/4.1 Regression] error: cannot appear
in a constant-expression

Hi,
Is this bug fixed? I'm still unable to use a static constant in
an expression to declare another static constant. I'm using gcc version
4.0.1

Thanks,

Sridhar

Not yet, I still have to find some time to commit the patch. It will be fixed
in GCC 4.1 and GCC 4.0.2.

I applied that patch, but am still having the same problem. Any ideas?

It seems this works:
#include <math.h>
#include <stdio.h>

static const double PI = M_PI;
static const double TWPI = (2.0*PI);
static const double HALF_PI = (M_PI_2);
static const double QUARTER_PI = (M_PI_4);

main (int argc, char** argv) {
int i = 0;
printf("%ld\n", i);
return 0;
}

But putting these inside of a class doesn't work:

class Foo {
Foo(){};
~Foo(){};
static const double PI = M_PI;
static const double TWPI = (2.0*PI);
static const double HALF_PI = (M_PI_2);
static const double QUARTER_PI = (M_PI_4);
};

Giovanni, any news?

However strange it may seem, this is not valid C
