On most platforms, MySQL doesn't build or support .so (shared) client libraries by default, because building with shared libraries has caused us problems in the past.

In cases like this, you have to download the MySQL distribution and configure it with these options:

--without-server --enable-shared

To build shared driver libraries, you must specify the --enable-shared option for configure. By default, configure does not enable this option.

If you have configured with the --disable-shared option, you can build the .so file from the static libraries using the following commands:

shell> cd MyODBC-3.51.01
shell> make
shell> cd driver
shell> CC=/usr/bin/gcc \
       $CC -bundle -flat_namespace -undefined error \
           -o .libs/libmyodbc3-3.51.01.so \
           catalog.o connect.o cursor.o dll.o error.o execute.o \
           handle.o info.o misc.o myodbc3.o options.o prepare.o \
           results.o transact.o utility.o \
           -L/usr/local/mysql/lib/mysql/ \
           -L/usr/local/iodbc/lib/ \
           -lz -lc -lmysqlclient -liodbcinst

Make sure to change -liodbcinst to -lodbcinst if you are using unixODBC instead of iODBC, and configure the library paths accordingly.

This builds and places the libmyodbc3-3.51.01.so file in the .libs directory. Copy this file to MyODBC library directory (/usr/local/lib (or the lib directory under the installation directory that you supplied with the --prefix).

shell> cd .libs
shell> cp libmyodbc3-3.51.01.so /usr/local/lib
shell> cd /usr/local/lib
shell> ln -s libmyodbc3-3.51.01.so libmyodbc3.so

To build the thread-safe driver library:

shell> CC=/usr/bin/gcc \
       $CC -bundle -flat_namespace -undefined error
	      -o .libs/libmyodbc3_r-3.51.01.so
	      catalog.o connect.o cursor.o dll.o error.o execute.o
	      handle.o info.o misc.o myodbc3.o options.o prepare.o
	      results.o transact.o utility.o
	      -L/usr/local/mysql/lib/mysql/
	      -L/usr/local/iodbc/lib/
	      -lz -lc -lmysqlclient_r -liodbcinst
