I use this header file in my code, and meet this error

return vreinterpret_m64_s32(

Hi @wangmlshadow ,
For my experience, this may be caused that the compiler cannot find the arm_neon.h or your platform does not support this intrinsic (vrndiq_f32 is only available on AArch64).

Can you share your compile environment here so that we can have a thorough investigation?

Your GCC version is too old. GCC 4.8.0 was release in 2013, and it might not support AArch64 well. Please download the Linaro Toolchain instead.
