26.1.7.8. Building Shared Libraries
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
