This section describes aspects of building Connector/C++ applications that are specific to macOS. For general application-building information, see Section 2.5.1, “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
app.cc, and links dynamically to the
connector library, the
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.
