 For example my target use SQLite built in the rootfs. The sqlite

 I would like to know how to build the sysroot to add those files in the

 you want to add more packages into the sysroot built by meta-toolchain,
 you may add your extra packages(i.e. libsqlite3-dev) into the variable 
"TOOLCHAIN_TARGET_TASK".

Hi Lianhao,

Thanks for your help ! I have created my own meta-toolchain based on meta-toolchain-gmae.bb and it's work nicely.
However, there remains a small problem. My own meta-toolchain-perso.bb file is stored in my own layer meta-perso.
To include the meta-toolchain.bb with require I need to use the full 
path to the meta layer: require 
../../../meta/recipes-core/meta/meta-toolchain.bb
This is not really clean, do you know how to point the meta-toolchain.bb file without using the full path ?

Thanks again for your help
