I have a timer program which uses clock_gettime. This requires -lpthread option to compile successfully or else it gets undefined reference to 'clock_gettime' error.
As so far I explored that we can generate preprocessor warning messages with #warning and check if the include is present by #if __has_include("<pthread.h>"). But checking those does not really check if clock_gettime function is defined.
Just curious if I can make a custom message to warn people at compile time or preprocessing time who compiled without it to include -lpthread option.
I am using MinGW on Windows.
