I want to use Intel’s current compiler on Linux. I have an inline macro which is supposed to detect the compiler.
It used to work with past versions of GCC and ICC. But now I get extern inline with ICC. Does ICC now define __GNUC__? How would you detect ICC or Intel’s C++ compiler, ICPC?
#ifndef INLINE
# if defined(__GNUC__) || defined(__GNUG__)
# define INLINE extern inline
# else
# define INLINE inline
# endif
#endif
__INTEL_COMPILERis what you are looking for. (Source: ICC man page)
