I don't think that this is the problem but you may try the latest
version 15.08 [1]. If you do so, please create a new build directory
with the updated 'create_builddir' to avoid inconsistencies.

This is strange. I've tested these commands manually and they work just
fine. Have you added the following to your '<BUILD_DIR>/etc/build.conf':

REPOSITORIES += $(GENODE_DIR)/repos/hello_tutorial

If yes, could you please send the output of the following:

/usr/local/genode-gcc/bin/genode-arm-readelf --version

I'm a litte confused. The ARM PBXA9 board is merely used as a reference
design with Qemu and an Uboot image is not needed for booting in this
case. Thus, '--include image/uboot' doesn't make much sense and the
RUN_OPT of a freshly created build directory for hw_pbxa9 normally
doesn't contain this argument. However, even if I add it to my RUN_OPT,
'make run/hello' finishes and the corresponding Uboot image [2] gets
created.

Cheers,
Martin
