To build the driver on Mac OS X (Darwin), make use of the following configure example:

shell> ./configure --prefix=/usr/local
           --with-unixODBC=/usr/local
           --with-mysql-path=/usr/local/mysql
           --disable-shared
           --enable-gui=no
           --host=powerpc-apple

The command assumes that the unixODBC and MySQL are installed in the default locations. If not, configure accordingly.

On Mac OS X, --enable-shared builds .dylib files by default. You can build .so files like this:

shell> make
shell> cd driver
shell> CC=/usr/bin/gcc \
     $CC -bundle -flat_namespace -undefined error
         -o .libs/libmyodbc3-3.51.01.so *.o
         -L/usr/local/mysql/lib/
         -L/usr/local/iodbc/lib
         -liodbcinst -lmysqlclient -lz -lc

To build the thread-safe driver library:

shell> CC=/usr/bin/gcc \
     $CC -bundle -flat_namespace -undefined error
     -o .libs/libmyodbc3-3.51.01.so *.o
     -L/usr/local/mysql/lib/
     -L/usr/local/iodbc/lib
     -liodbcinst -lmysqlclienti_r -lz -lc -lpthread

Make sure to change the -liodbcinst to -lodbcinst in case of using unixODBC instead of iODBC and configure the libraries path accordingly.

In Apple's version of GCC, both cc and gcc are actually symbolic links to gcc3.

Copy this library to the $prefix/lib directory and symlink to libmyodbc3.so.

You can cross-check the output shared-library properties using this command:

shell> otool -LD .libs/libmyodbc3-3.51.01.so
