ac_check_mysqlr

First check if mysqlconfig exists. It fails if mysqlconfig is not in path. Then it checks for the libraries and replaces -lmysqlclient statement with -lmysqlclient_r statement, to enable threaded client library.

The following are exported environment variables:

  MYSQL_LIBS
  MYSQL_CFLAGS

AC_DEFUN([AC_CHECK_MYSQLR],[
AC_PATH_PROG(mysqlconfig,mysql_config)
if test [ -z "$mysqlconfig" ]
then
    AC_MSG_ERROR([mysql_config executable not found])
else
    AC_MSG_CHECKING(mysql libraries)
    MYSQL_LIBS=`${mysqlconfig} --libs | sed -e \
    's/-lmysqlclient /-lmysqlclient_r /' -e 's/-lmysqlclient$/-lmysqlclient_r/'`
    AC_MSG_RESULT($MYSQL_LIBS)
    AC_MSG_CHECKING(mysql includes)
    MYSQL_CFLAGS=`${mysqlconfig} --cflags`
    AC_MSG_RESULT($MYSQL_CFLAGS)
