Thanks for that,  I found this answer myself in the end (different
install directory),  maybe the bit script needs a quick mod ?


Anyway,  having followed your instructions too the letter, the tools
build OK, now (gdb too, as far as I can tell atm).  My problem now is
getting rtems to build.  I've reached as up to your line "./bit_rtems
i386 pc386" without problems, but the result of this is as follows :

I tried the compiler to see if it runs at all :

bash-2.02$ i386-rtems-gcc -dumpmachine
i386-rtems

then I tried a hello world compile on a file hello.c containing :

__start
#include <stdio.h>

int main()
{
        printf ("hello world !");
        return 0;
}
__end



bash-2.02$ i386-rtems-gcc hello.c -o hello.exe

It seems as if the rtems compiler can't find its libraries or something,
have I missed out some simple "export" statement or something ?


Thanks for your help,
