__visible is defined like this: /* * Optional: not supported by clang * * gcc: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-externally_005fvisible-function-attribute */ #if __has_attribute(__externally_visible__) # define __visible __attribute__((__externally_visible__)) #else # define __visible #endif It says clang does not support this.
