Dear OE hackers,


sorry for bothering you with this. I am trying to reproduce the errors
Henning has seen with g++ 4.4.2 [1] and therefore added the following
lines to my `local.conf` for Ångström with BeagleBoard [2].

I do not get these errors if I use the standard versions defined for
Ångström which is 4.1.1. Adding `-fPIC` to the flags as suggested in [3]
solves the problem for me.

Does anyone know if GCC’s behavior was changed somehow?


Thanks,

Paul
