[ECOS] ecos-3.0 in linux target segfault

[Daniel Widyanto]

Hi all,

I have just downloaded ecos-3.0 using ecos-install.tcl. I want to evaluate ecos in my PC, before committing effort to run it in LPC17xx (ARM Cortex-M3 platform).

I use Ubuntu 9.10, and have managed to recompile the ecosconfig using libstdc++6 (since the supplied ecosconfig can only run with libstdc++5, which is not available in Ubuntu 9.10).

I use these commands to create ecos kernel for linux target:
--------------------------------------------
bash# ecosconfig --prefix=$HOME/projects/x86_ecos/kernel new linux
bash# ecosconfig --prefix=$HOME/projects/x86_ecos/kernel tree
bash# make
--------------------------------------------

The ecos kernel was compiled and installed normally. Then I try to compile the hello world
--------------------------------------------
bash# vi hello.c
#include <stdio.h>
int main(void)
{
 printf("Hello, eCos world!\n");
 return 0;
}
:qw

bash# gcc -g -I$HOME/projects/x86_ecos/kernel/include hello.c \
-L$HOME/projects/x86_ecos/kernel/lib -Ttarget.ld -nostdlib
--------------------------------------------

It also compiled correctly. But when I run the code example, I got SIGSEGV (segmentation fault):
--------------------------------------------
bash# gdb -nw a.out

--------------------------------------------

Is there anything that I can do to fix this one ?

Thank you for your help
