qemu-system-x86_64: Display 'sdl' is not available.

Aborting, received EOF

Was my qemu tools not matching the genode version ? Any workaround method to display the result ?

It seems your Qemu does not support the SDL backend. Please try to comment out (or delete) the following line in <build-dir>/etc/build.conf.

QEMU_OPT += -display sdl
