We need to decompose the functionname into a series of namespaces -dnl where it gets declared so that it can be used for a link test. -dnl -dnl In the first version I did allow namespace::functionname to be a -dnl reference to a void-argument global functionname (just wrapped in a -dnl namespace) like its C counterparts would be - but in reality such -dnl thing does not exist. The only global / static functions are always -dnl made const-functions which is an attribute mangled along into the -dnl library function export name. -dnl -dnl The normal usage will ask for a test of a class-member function which -dnl should be presented with a full function spec with arguments given in -dnl parentheses following the function name - if the function to test for -dnl does expect arguments then you should add default initial values in the -dnl prototype (even if they do not exist originally, these are used only -dnl locally to build a correct function call in the configure test script). -dnl -dnl In the current version if you do omit the parenthesis from the macro -dnl argument then the macro will assume that you want to check for the -dnl class name - which is really to check for default constructor being -dnl exported from the given library name. -dnl -dnl EXAMPLE: -dnl AX_CXX_CHECK_LIB(cgicc, [cgicc::HTTPCookie]) -dnl AX_CXX_CHECK_LIB(cgicc, [cgicc::Cgicc::getVersion () const], -dnl AX_CXX_CHECK_LIB(boost_regex, [boost::RegEx::Position (int i = 0) const]) -dnl -dnl Result: -dnl Just as the usual AX_CXX_CHECK_LIB - defines HAVE_LIBCGICC -dnl and adds the libraries to the default library path (and -dnl uses internally the normal ac_check_lib cache symbol -dnl like ac_cv_lib_cgicc_cgicc__Cgicc) -dnl -dnl Footnote: The C++ language is not good at creating stable library -dnl interfaces at the binary level - a lot of functionality is usually being -dnl given as inline functions plus there is hardly a chance to create opaque -dnl types. Therefore most C++ library tests will only do compile tests using -dnl the header files. Doing a check_lib is however good to check the link -dnl dependency before hitting it as an error in the build later. -dnl -dnl @category C++ -dnl @author Guido U.
