Hi all.

I cave in and admit that the system outsmarted me.
Here goes newbie question. :)
Compiling RTEMS for a LEON2 simulator in a Linux (Ubuntu 7.04) machine.
autoconf 2.61, automake 1.10, gcc 4,1,2.

I'm in the last step of the compilation described in the wiki's Quick Start:
> cd rtems
> export PATH=/opt/rtems-4.8/bin:$PATH
> ./bootstrap
> cd ..
> mkdir b-sis
> cd b-sis
> ../rtems/configure --target=sparc-rtems --enable-rtemsbsp=sis
--enable-tests=samples --disable-posix --disable-itron
> make

Doing 'make all'.

I've been trying to fix it myself, but failed to understand how everything
is well except for nanosleep.
Can something not have been included properly?

Any pointers?
Thank you. :)
