I symlinked that arm_neon.h to /usr/include/arm_neon.h and now it finds it but says: "bad type in Neon instruction -- `vhadd.p8 q3,q3q2' so it seems like I do not have the correct arm_neon.h version - it is gcc-4.6 that I try but gcc-4.2 simply does not have arm_neon.h at all... So now what...? (I'm still trying to compile fcamera 0.1.7)
