Attempting to build an app for Beaglebone

Wed Jul 1 23:25:40 UTC 2015

I followed Ben's tutorial.

 % ../source-builder/sb-set-builder --log=beagle.txt
--prefix=$HOME/development/rtems/4.11 devel/beagle.bset

and

 % mkdir b-beagle ; cd b-beagle
    % CONSOLE_POLLED=1 ../rtems-src/configure --target=arm-rtems4.11
--enable-rtemsbsp="beagleboneblack beagleboardxm" --enable-tests
    % make

I have done a grep for that file and it comes up like this

angelo at debian:~/development$ find -name leaf.cfg
./rtems/b-beagle/arm-rtems4.11/c/beagleboardxm/make/leaf.cfg
./rtems/b-beagle/arm-rtems4.11/c/beagleboneblack/make/leaf.cfg
./rtems/rtems-src/make/leaf.cfg
./rtems/rtems-src/c/src/make/leaf.cfg

So I decided to do a symlink
root at debian:/opt# ln -s
/home/angelo/development/rtems/b-beagle/arm-rtems4.11/c/
   beagleboneblack/ /opt/rtems-4.11

Now when I go make, I get the error
make: *** No rule to make target `/init.o', needed by `/gpio.exe'.  Stop.

So it seems that ARCH is not being defined somewhere that it needs to be.
So making the symlink is not the solution.
Also, looking at RTEMS doc,
https://docs.rtems.org/doc-current/share/rtems/pdf/started.pdf, it said it
was supposed to install to /opt/rtems-4.11 by default, which it did not.
