<stdin>:1:14: fatal error: 'math.h' file not found
#include <math.h>
^~~~~~~~
1 error generated.
math.h
is located in /Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk/usr/include
, which is only discovered by the system Clang.
Looks like this is related to sysroot discovery; adding -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk
or defining SDKROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk
"fixes" the issue.
