dnl @synopsis AX_BOOST_FOR_BIND10
|
||
|
|
dnl
|
||
|
|
dnl Test for the Boost C++ header files intended to be used within BIND 10
|
||
|
|
dnl
|
||
|
|
dnl If no path to the installed boost header files is given via the
|
||
|
|
dnl --with-boost-include option, the macro searchs under
|
||
|
|
dnl /usr/local /usr/pkg /opt /opt/local directories.
|
||
|
|
dnl If it cannot detect any workable path for Boost, this macro treats it
|
||
|
|
dnl as a fatal error (so it cannot be called if the availability of Boost
|
||
|
|
dnl is optional).
|
||
|
|
dnl
|
||
|
|
dnl This macro also tries to identify some known portability issues, and
|
||
|
|
dnl sets corresponding variables so the caller can react to (or ignore,
|
||
|
|
dnl depending on other configuration) specific issues appropriately.
|
||
|
|
dnl
|
||
|
|
dnl This macro calls:
|
||
|
|
dnl
|
||
|
|
dnl AC_SUBST(BOOST_INCLUDES)
|
||
|
|
dnl
|
||
|
|
dnl And possibly sets:
|
||
|
|
dnl CPPFLAGS_BOOST_THREADCONF should be added to CPPFLAGS by caller
|
||
|
|
dnl BOOST_OFFSET_PTR_WOULDFAIL set to yes if offset_ptr would cause build
|
||
|
|
dnl error; otherwise set to no
