Hello,
i’m trying to use bitbake and yocto with the connectardim28js.
So far, i have succefully created my image with my own recipes using bitbake. But there are some more questions:
a) Is it possibile to add all recipes of a layer? At the moment i add every recipe on its own with the local.conf line “IMAGE\_INSTALL\_append = …”
b) What is the correct way to set the default root password and hostname? I tried the following line, without success:
DISTRO\_HOSTNAME = “coffeeroaster”
inherit extrausers
EXTRA\_USERS\_PARAMS = “usermod -P password root;”
c) How do i remove default software distributed by the digi layer? In the local.conf there is for example no line for the default webserver. Do i have to edit the layer?
d) I try to use eclipse to create my own project. Creating a C++ project my linker seem to not knowing my own classes. I get always undefined reference error for my own classes and its methods. Its a very basic Hello World programm with a testclass printing “Hello World”. In eclipse I choosed “Hello World C++ Autotools Project”
Thank you very much for you help!

a) I think what you want is to create your own layer
Create your own custom layer. Poky provides a script to create custom layers:
# cd /usr/local/dey-2.0/sources
# ./poky/scripts/yocto-layer create your\_layer
b) I succesfully used 2 lines below to add a new user:
inherit extrausers
EXTRA\_USERS\_PARAMS = “useradd -P 2015\*08 leonidm;”
more details and examples here:
> **[FAQ:How do I set or change the root password - Yocto Project](https://wiki.yoctoproject.org/wiki/FAQ:How_do_I_set_or_change_the_root_password)**
inherit extrausers
EXTRA\_USERS\_PARAMS = “usermod -P 1876\*18 root;”
c) modify meta-digi layer
d) please take a look at this presentation:

Alright I’m working on it, but just another question:
Using Eclipse I am wondering how to add the sqlite3 library? I can use #include “sqlite3.h” and the file is found. But i always get an error “undefined reference”.
Using the autotools c++ project it seems to not have the classic library section under properties -\> c++ build.
