Thanks a lot for the hint. Got it all fixed. Now I can get image.elf to
compile and readelf -s returns:
22790: 00000000 112 FUNC GLOBAL DEFAULT 3735 _ZN6Genode3Log3logEv
Ran into "undefined reference" again with io_port* files but was able to
fix by changing vpath for platform_services.cc
from: $(GEN_CORE_DIR)/spec/x86 to $(GEN_CORE_DIR).
Running the image on board gave no result, apart from msg: ## Starting
application at 0x10001000 ...
Is it possible that I might be missing some i.MX6 platform specific files
in my build? Like those that can be found in
/base-hw/src/core/spec and /base-hw/src/core/include/spec
