# SYNOPSIS
|
|
#
|
|
# AX_LIB_MYSQL([MINIMUM-VERSION])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro provides tests of availability of MySQL client library
|
|
# of particular version or newer.
|
|
#
|
|
# AX_LIB_MYSQL macro takes only one argument which is optional. If
|
|
# there is no required version passed, then macro does not run
|
|
# version test.
|
|
#
|
|
# The --with-mysql option takes one of three possible values:
|
|
#
|
|
# no - do not check for MySQL client library
|
|
#
|
|
# yes - do check for MySQL library in standard locations
|
|
# (mysql_config should be in the PATH)
|
|
#
|
|
# path - complete path to mysql_config utility, use this option if
|
|
# mysql_config can't be found in the PATH
|
|
#
|
|
# This macro calls:
|
|
#
|
|
# AC_SUBST(MYSQL_CFLAGS)
|
|
# AC_SUBST(MYSQL_LDFLAGS)
|
|
# AC_SUBST(MYSQL_VERSION)
|
|
#
|
|
# And sets:
|
|
#
|
|
# HAVE_MYSQL
|
|
