antmerlino opened a new issue #3456:
URL: https://github.com/apache/incubator-nuttx/issues/3456


   I had a very simple configuration for a board that worked at some point and I ran into build errors because it was looking for math.h and I didn't have CONFIG_LIBM on.
   
   Looks like the below change moved types and subsequent includes.
   
   https://github.com/apache/incubator-nuttx/commit/d17b963bcab98e2d2f641623547837a8d3fe94cd
   
   Do we want to fix this, or do we want to require that users provide a math.h, either via CONFIG_LIBM, toolchain, or otherwise? 
   
   If we did want to fix, I think we need to:
   
   1. guard every place in libc that uses float/double with CONFIG_LIBC_FLOATINGPOINT
   2. guard the include with either CONFIG_LIBC_FLOATINGPOINT or CONFIG_LIBM
