22.1.2 Compiling Programs with `libmysqld'
------------------------------------------
To get a `libmysqld' library you should configure MySQL with the
-with-embedded-server option. See configure-options.
When you link your program with `libmysqld', you must also include the
system-specific `pthread' libraries and some libraries that the MySQL
server uses. You can get the full list of libraries by executing
`mysql_config --libmysqld-libs'.
The correct flags for compiling and linking a threaded program must be
used, even if you do not directly call any thread functions in your
code.
To compile a C program to include the necessary files to embed the
MySQL server library into a compiled version of a program, use the GNU
C compiler (`gcc'). The compiler will need to know where to find
various files and need instructions on how to compile the program. The
following example shows how a program could be compiled from the command
line:
gcc mysql_test.c -o mysql_test -lz \
`/usr/local/mysql/bin/mysql_config --include --libmysqld-libs`
Immediately following the `gcc' command is the name of the uncompiled C
program file. After it, the -o option is given to indicate that the file
name that follows is the name that the compiler is to give to the
output file, the compiled program. The next line of code tells the
compiler to obtain the location of the include files and libraries and
other settings for the system on which it's compiled. Because of a
problem with `mysql_config', the option -lz (for compression) is added
here. The `mysql_config' piece is contained in backticks, not single
quotes.
