Ok I will upgrade my version of eCos. But I have to compile it ? I will
only download the source of eCos ?
To install eCos on my PC, I used the script ecos-install.tcl and I just
update my PATH and export some variable...
Thanks you for all
Best regards
David LONY

Hi all,
I'm new to ecos and I've have some problem with the Hello World program
on Linux Synthetic Target (default template). I'm sucessfully compile
eCos on the configtool with these options :
-Wall -Wpointer-arith -Winline -Wundef -Woverloaded-virtual -g -O2
-ffunction-sections -fdata-sections -fno-rtti -fno-exceptions -fvtable-gc
for Global Compiler Flags
and
-g -nostdlib -Wl,--gc-sections -Wl,-static
for Global Linker Flags
then i compile a small program :
#include <stdio.h>
int main(void)
{
printf("Hello, eCos world!\n");
return 0;
}
like this : gcc -g -ILinux_install/include main.c -LLinux_install/lib
-Ttarget.ld -nostdlib
then I try to debug the final executable with gdb like that :

eCos 2.0 is very, very old. First i suggest you update to anoncvs.
