C++ global objects

The NiosII linker fails to call constructors for static global objects.

A simple example:

test.h:# include <math.h>

const double PI = 3.14159265;

class Circle

{

protected:

double radius;

public:

Circle(double = 1.0);

double calcval();

};

test.cxx:# include "test.h"

Circle::Circle(double r)

{

radius = r;

}

double Circle::calcval(void)

{

return(PI * radius * radius);

}

testprog.cxx:# include <stdlib.h># include <stdio.h># include "test.h"

static Circle circle_1(10);

int main()

{

printf("The area of circle_1 is %f\n", circle_1.calcval());

exit (0);

}

This fails. Circle_1 will always be 0. Putting the declaration inside main works:

int main()

{

Circle circle_1(10);

printf("The area of circle_1 is %f\n", circle_1.calcval());

exit (0);

}

Have anyone else experienced this ? Is it a g++ or ld bug, or do there exist any magic compiler/linker flags that I&#39;m missing ?

(The example code works fine with gcc 3.4.1 on x86).
