[Matteo]

Hi
I have intel centrno and linux ubuntu and I would like install RTEMS.
I download rtems-4.6.5.tar.bz2 and I uncompressed and untar in
/myhome/rtems/rtems-src/      sun after I do 
/myhome/rtems/rtems-b/../rtems-src/configure
and all ok at the end of configuration a message said to me to do make all to
build for posix and I do it
/myhome/rtems/rtems-b/make all 
but I had a problem like the follow;

...
Making all in rtems
