};
int main() {}
test.cpp: In constructor 'constexpr cond_variable::cond_variable()':
test.cpp:7:84: error: could not convert '{{0, 0}, 0, "", 0}' from

class mutex

::pthread_mutex_t mtx;
public:
constexpr mutex() : mtx(PTHREAD_MUTEX_INITIALIZER) {}
};
Compiles fine... What is the difference?

That your libc does not provide a C++ compatible initializer for
pthread_cond_t?
Without preprocessed source we can't tell. Please attach that.

The request to support ({ ... }) for array mem-initializers was rejected by
core:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_closed.html#1339
Now that the compiler supports non-static data member initializers, the library
should use that instead of a mem-initializer.
::pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
should work in all cases.
