dnl @synopsis AX_BOOST_REGEX
|
|
dnl
|
|
dnl This macro checks to see if the Boost.Regex library is installed.
|
|
dnl It also attempts to guess the currect library name using several
|
|
dnl attempts. It tries to build the library name using a user supplied
|
|
dnl name or suffix and then just the raw library.
|
|
dnl
|
|
dnl If the library is found, HAVE_BOOST_REGEX is defined and
|
|
dnl BOOST_REGEX_LIB is set to the name of the library.
|
|
dnl
|
|
dnl This macro calls AC_SUBST(BOOST_REGEX_LIB).
