Yocto compilation error (shm.h)

[dgotfroi]

Hello

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

But I've a compilation error :

Can you help me ?

[dgotfroi · Accepted solution]

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.
