[En-Nut-Discussion] charon2 db_demo errors

[Aigars Riekstinsh]

Hello.

Im new to ethernut and nut/os and so please excuse me if this is
answered many times but I didnt find answers in list archives.

I installed an configured nut/os for ethernut v 2.1 on windows. I
succesfully built nutos and sample applications in seperate built trees
but now I need to develop for charon2 moule also. I understand that it
shoud be possible to use the same souce tree ounly make new built tree
and application tree with nutconf. I did it with ethernut13f.conf as
starting point and nut/os builds OK (didnt test it on hw) but make in
db_demo folder gives me:

Do I need to change/install second sw tree or there is something more
than needs for changes in UserConf.mk and makefile for db_demo?
Is it possible to use one development tool/notos tree for both charon2
and ethernut 2?
