Initializers must be compile time constants (not expressions!) for clang to be happy. Clang rightfully pointed out that the callback_list member of sensing_connection was being initialized using an expression that was not compile-time constant. The macros passed along a pointer created by taking the address of a global constant and then at initialization time attempting to dereference it using the * operator. So in the end the compiler has identifier its trying to first take the address of and then later dereference in an initializer. Clang didn't appreciate this, though gcc seemed to be just fine. Actually clang 17 might work just fine with this as well, but clang 16 (the clang I tried) didn't like it at all. Instead store the pointer to the callback list rather than copying the struct. This could be done the other way and not passing a pointer through the macros perhaps. Signed-off-by: Tom Burdick <thomas.burdick@intel.com> |
