[ECOS] arm-elf-g++ problem

Hello,

I am trying to compile some software for the Atmel AT91 processor under
eCos. However, I am having trouble with my compiler. I built the arm-elf
toolchain using the instructions on the eCos website. I then used the
eCos configtool to configure eCos for the default Atmel evaluation board
(EB40). However, if I try to compile:

//#include <stdio.h>
#include <iostream>

int main()
{

//    printf("Hello\n\r");
    cout << "Hello\n";

}


Using the command:

arm-elf-g++ -I /home/johnm/ecos-work/arm_install/include test1.cpp -c


Then I get lots of errors. The included directory was produced by the
eCos configtool. The first block of errors are:

johnm@johnm-desktop:~/ecos_play$ arm-elf-g++
-I /home/johnm/ecos-work/arm_install/include test1.cpp -c

not
   declared

If I comment out the C++ lines and comment in the C lines then an object
file is successfully produced. Does anyone know what is wrong here.

Regards,
John Macdonald
