On the other hand "just to give it a try" it's a major effort to add kernel and bootloader to poky and moreover the gcc which comes with poky is not always what I need in terms of stability but also features (need e.g. Cortex-A8 support). So I would also need to cook gcc to compile a vendor provided kernel and bootloader. What I'm after is to add some packages from poky to some 3rd party rootfs. One major problem I have is the dependency on libc6 (>= 2.12) Usually I have some older versions of libc6: e.g. libc-2.8.so. For the projects I'm currently working on kernel and bootloader are already compiling/running and tested and I would like to add packages like qt-embedded to the various rootfs. To achieve this I would need a mechanism to use a 3rd party toolchain with poky (and maybe to skip the build steps for kernel and boot loader). Is this something yocto/poky was made for, or am I totally off? Am I the only one who has such kind of problems? How are others tackling these kind of problems?
