Hello

I'm trying to bitbake a Core-image-minimal with yocto daisy(for an imx28evk board).

But I've a compilation error :

ERROR: Function failed: do_compile (log file is located at /home/gwio/fsl-community-bsp/build/tmp/work/x86_64-linux/perl-native/5.14.3-r0/temp/log.do_compile.17607)

I think I found the solution by myself.

I edited sys/shm.h and I added : "#define HAS_SHMAT_PROTOTYPE".

In this case, doio.c will not try to redefined SHMAT prototype and perl compiles with no error.
