##### http://autoconf-archive.cryp.to/ax_lib_mysql.html # # 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_LIBS) # AC_SUBST(MYSQL_VERSION) # # And sets: # # HAVE_MYSQL # # LAST MODIFICATION # # 2006-07-16 # # COPYLEFT # # Copyright (c) 2006 Mateusz Loskot # # Copying and distribution of this file, with or without # modification, are permitted in any medium without royalty provided # the copyright notice and this notice are preserved.
