This section describes aspects of building Connector/C++ applications that are specific to macOS. For general application-building information, see Section 5.1, “Building Connector/C++ Applications: General Considerations”.

The binary distribution of Connector/C++ for macOS is compiled using the macOS native clang compiler. For that reason, an application that uses Connector/C++ should be built with the same clang compiler.

The clang compiler can use two different implementations of the C++ runtime library: either the native libc++ or the GNU libstdc++ library. It is important that an application uses the same runtime implementation as Connector/C++ that is, the native libc++. To ensure that, the -stdlib=libc++ option should be passed to the compiler and the linker invocations.

To build a Connector/C++ application that uses X DevAPI, has sources in app.cc, and links dynamically to the connector library, the Makefile for building on macOS might look like this:

MYSQL_CONCPP_DIR = Connector/C++ installation ___location
CPPFLAGS = -I $(MYSQL_CONCPP_DIR)/include -L $(MYSQL_CONCPP_DIR)/lib64
LDLIBS = -lmysqlcppconn8
CXX = clang++ -stdlib=libc++
CXXFLAGS = -std=c++17
app : app.cc

Binary packages for macOS include OpenSSL libraries that are required by code linked with the connector. These libraries are installed in the same ___location as the connector libraries and should be found there by the dynamic linker.
