4 # SYNOPSIS
5 #
6 # AX_LIB_MYSQL([MINIMUM-VERSION])
7 #
8 # DESCRIPTION
9 #
10 # This macro provides tests of availability of MySQL 'libmysqlclient'
11 # library of particular version or newer.
12 #
13 # AX_LIB_MYSQL macro takes only one argument which is optional.
14 # If there is no required version passed, then macro does not run
15 # version test.
16 #
17 # The --with-mysql option takes one of three possible values:
18 #
19 # no - do not check for MySQL client library
20 #
21 # yes - do check for MySQL library in standard locations
22 # (mysql_config should be in the PATH)
23 #
24 # path - complete path to mysql_config utility, use this option if
25 # mysql_config can't be found in the PATH
26 #
27 # This macro calls:
28 #
29 # AC_SUBST([MYSQL_CFLAGS])
30 # AC_SUBST([MYSQL_CPPFLAGS])
31 # AC_SUBST([MYSQL_LDFLAGS])
32 # AC_SUBST([MYSQL_VERSION])
33 #
34 # And sets:
35 #
36 # HAVE_MYSQL
37 #
38 # LAST MODIFICATION
39 #
40 # 2006-07-16
41 # 2007-01-09 MKS: mysql_config --cflags may set gcc -fomit-frame-pointers,
42 # which prevents gdb from displaying stack traces.
43 # Changed mysql_config --cflags to mysql_config --include
44 # 2009-09-23 AJB: Checking for availability of both, include files and
45 # library files.
46 # 2010-06-14 MKS: Added MYSQL_CPPFLAGS
47 # 2011-08-01 MKS: Made test constructs more portable
