Building CrossGCC for ARM ...

["Ramapriya Rangachar" <ramapriya1 at hotmail dot com>]

HI All

Im trying to build an ARM toolchain hosted on Win2k+Cygwin

This is the procedure I used to build the toolchain:

1. Binutils 		(binutils-20011002-1)
2. Bootstrap GCC
3. Newlib		(newlib-1.10.0)
4. GCC			(gcc-2.95.3-5)
5. Insight		(insight-5.1.1)

I have the foll. problem

Code:
----------------------------------------------------------------------------------
#include <stdio.h>
#include <math.h>

int main()
{
	double a = 0.125;

    printf("Hello World!\n");

    a *= a;

    a = pow(2, a);

    return(0);
}
----------------------------------------------------------------------------------

Error:

I'm not sure why the linker cannot resolve the ref.

Can tell me with right build procedure?
I can send my build-script over, if someone wants to look at it ...

Thanks
Ram
