[ECOS] compiling c++ with ecos

[Jörn Seger <joern dot seger at udo dot edu>]

Hi there,

(I'm sorry if this question was asked befor, but the ht-dig is not able to 
find names like "c++" ;-))

I've got a strange problem here while cross-compiling an project for an arm 
embedded processor. 

I compiled a very simple hello world programm and compiled it as said in the 
Users Guide. Then I try to compile it with 

#include<iostream> instead of <stdio.h>
and with std::cout<< instead of printf
 
and then the output looks like below.

HISTORY:
For toolchain building, I used the instructions on the ecos-webside (with 
binutils-2.13.1, gcc-3.2.1(core and c++), insight-5.3, newlib 1.11.0 and all 
the patches available for arm-elf)

I compiled ecos (and the configtool) as it was shiped by the AIM711 (version 
said it was from 19.Feb.2004 (cvs??)) and used the description for 
installation on SuSE by a friendly guy from the net (can't remember his name)

Then I created a project from a template shiped with AIM711 and compiled the 
hello world - what worked fine until I try to compile c++-code

Thanks in advance -
Jörn
