I've been supporting this by keeping the older code around in my own layers - I need 4.7.x for some targets, even 4.6.x for others. With the changes in the latest master (post 1.6/daisy), I am no longer able to build those older compilers :-( First I had to fix up some core changes to just get the recipes to even parse (bb.utils.contains), but now I get a slew of errors like these: NOTE: preferred version 4.7% of libgcc-initial not available (for item libgcc-initial) NOTE: versions of libgcc-initial available: 4.8.2 4.9.0 I looked at the old recipes and they don't provide these packages which make them unsuitable. I know I should move these targets to the newer GCC, but at this moment there simply are not the resources to do so, but we still want to benefit from other improvements in OE-core (and Poky/Yocto). How can I move forward? Is there some way to retrofit the older compilers into the new [required] structures? Perhaps I could use the older compilers as external tool chain, but the last time I tried to use this (in place of the internal, build in place) tools, I could never make things happy :-( Any suggestions more than welcome, thanks -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
