Headers not found after updating t… | Apple Developer Forums

Hi there,

I recently grabbed the latest version of the 10.15 beta on a new computer and I have been trying to setup some command-line software that was working on my older machines running 10.13 and 10.14. Trying to build libfreenect (an open source library to interface with an Xbox 360 Kinect) with `make` gives me this error:

$ make
[  1%] Building C object src/CMakeFiles/freenectstatic.dir/core.c.o
/Users/billjobs/code/libfreenect/src/core.c:27:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
         ^~~~~~~~~
1 error generated.
make[2]: *** [src/CMakeFiles/freenectstatic.dir/core.c.o] Error 1
make[1]: *** [src/CMakeFiles/freenectstatic.dir/all] Error 2
make: *** [all] Error 2

I have installed Xcode's command-line tools but after doing some research it seems like 10.15 has changed the way things normally work the paths to header files, etc. Does anyone have any insight on a fix/workaround? It doesn't make sense to me why these header files would be missing.
