For a particular library we are building - the configure.ac looks as follows: AC_CHECK_HEADERS(libmyapp.h) . The location of libmyapp.h depends on the architecture / *nix distribution etc. The Makefile.am looks as follows: bin_PROGRAMS = hello hello_CFLAGS = -I /usr/fqpath If ./configure ( as output by autoconf succeeds while checking headers) , is there a macro variable that points to the fully qualified path that succeeded that macros , that can be later used by the automake tool as well (in Makefile.am ) ? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
