MySQL NDB Cluster API Developer Guide
It is often faster and simpler to use GNU autotools than to
write your own makefiles. In this section, we provide an
autoconf macro
WITH_MYSQL
that can be used to add a
--with-mysql
option to a configure file, and
that automatically sets the correct compiler and linker flags
for given MySQL installation.
All of the examples in this chapter include a common
mysql.m4
file defining
WITH_MYSQL
. A typical complete example
consists of the actual source file and the following helper
files:
acinclude
configure.in
Makefile.m4
automake also requires that you
provide README
, NEWS
,
AUTHORS
, and ChangeLog
files; however, these can be left empty.
To create all necessary build files, run the following:
aclocal
autoconf
automake -a -c
configure --with-mysql=/mysql/prefix/path
Normally, this needs to be done only once, after which make will accommodate any file changes.
Example 1-1: acinclude.m4.
m4_include([../mysql.m4])
Example 1-2: configure.in.
AC_INIT(example, 1.0) AM_INIT_AUTOMAKE(example, 1.0) WITH_MYSQL() AC_OUTPUT(Makefile)
Example 1-3: Makefile.am.
bin_PROGRAMS = example example_SOURCES = example.cc
Example 1-4: WITH_MYSQL source for inclusion in acinclude.m4.
