Hello there,
    
after some time of abstinence, I tried to build sculpt-19.07 by cloning the repo.
Following the orders in doc/getting_started.txt I installed the prebuilt toolchain and created a build dir per
cd
          <genode-dir>
          ./tool/create_builddir x86_64
After that I wanted to run the demo per:
cd
          build/x86_64
          make KERNEL=linux run/demo
        
        
but failed with:
schelm@ubuntu:~/Development/genode/build/x86_64$
          make KERNEL=linux run/demo
          including

Any idea?
        
Thanks in advance!
