arm_neon.h not found for imx8 yocto toolchain

[YihMin]

Hi all,

I am trying to compile Arm Ne10 lib, but come up with an "arm_neon.h not found" error.

Does the toolchain version I got not support NEON compilation?

Does any one have idea how to fix this problem?

My current toolchain is yocto for iMX8.

Thanks

Hi @YihMin 

It means the toolchain you are using don't contain arm_neon.h, also the official bsp don't contain this file.

You can try to add a yocto bb layer to build this lib.

Hi nxf65025,

Thanks for your response. I will check and try it.

So this recipe will add the NEON support to the official bsp?
