Csound 6. I call build with Release enabled, but the errors persist?  

cmake ---build . --config=Release

Turns out the Custom.cmake set the build back to debug. Thanks, I'm getting further now.

It seems there is no NEON support for RPi Zero, so I added the following to the Custom.cmake file:

set(CMAKE_FLAGS "${CMAKE_FLAGS} -DPFFFT_SIMD_DISABLE")

but building still fails:

You’re probably doing something wrong. I added to my Custom.cmake

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -DPFFFT_SIMD_DISABLE")

and I get this kind of command line
