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
In file included
from /home/johnm/ecos_toolchain/gnutools/arm-elf/include/arm-elf/bits/c
++io.h:35,
from /home/johnm/ecos_toolchain/gnutools/arm-elf/include/bits/fpos.h:44,

/home/johnm/ecos_toolchain/gnutools/arm-elf/include/cstdio:138: `tmpnam'
not

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

The C++ support for eCos is somewhat limited in anonymous
CVS. iostream is one of the things which do not work. Search the
archive for mor details.
If you want full c++ support, you probably want to license one of the
commercial forks of eCos, eg from eCosCentric.

Add "using namespace std;".
