How can compile-time static asserts be implemented in C (not C++), with particular emphasis on GCC?
C11 standard adds the
_Static_assertkeyword.This is implemented since gcc-4.6:
The first slot needs to be an integral constant expression. The second slot is a constant string literal which can be long (
_Static_assert(0, L"assertion of doom!")).I should note that this is also implemented in recent versions of clang.
