Building sysroot for SDK

Building sysroot for SDK

[Patrick]

Dear list,

I use poky 6.0 to build a complete rootfs for my own target, it's working nicely !Now I would like to build a small application SDK for my system. 

I have red carefully the ADT manual and decided to build a toolchain with meta-toolchain. The toolchain generated works properly but some libraries and headers are missing. 
For example my target use SQLite built in the rootfs. The sqlite library and the headers files are missing in the toolchain.

I would like to know how to build the sysroot to add those files in the toolchain or how to add it directly to the toolchain.

Thanks in advance for any help

Patrick

Hi Patrick,

If 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".  Meta/recipes-core/meta/meta-toolchain-gmae.bb might be an example of how to add more packages into the target sysroot.

Best Regards,
Lianhao

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

Patrick

I answer myself to my question:
I used a meta-toolchain.bbappend file placed in my own layer. This file append the libqlite3-dev package to the TOOLCHAIN_TARGET_TASK. 
This works fine !

Hi,

Should you not also be able to use your favourite package manager 
included in the toolchain tarball for this ?
opkg-cl -f /opt/poky/1.1/sysroots/ppce500mc-enea-linux/etc/opkg.conf 
--offline-root /opt/poky/1.1/sysroots/ppce500mc-enea-linux/ update
opkg-cl -f /opt/poky/1.1/sysroots/ppce500mc-enea-linux/etc/opkg.conf 
--offline-root /opt/poky/1.1/sysroots/ppce500mc-enea-linux/ install 
libsqlite3-dev
