When Config Files Go Bad

Posted by kev Thu, 08 Mar 2007 22:40:00 GMT

It is often necessary to check the content of a `configure.ac' file,
but parsing it yourself is extremely fragile and error-prone.  It is
suggested that you rely upon `--trace' to scan `configure.ac'.  For
instance, to find the list of variables that are substituted, use:


     $ autoconf -t AC_SUBST
     configure.ac:2:AC_SUBST:ECHO_C
     configure.ac:2:AC_SUBST:ECHO_N
     configure.ac:2:AC_SUBST:ECHO_T
     More traces deleted





-- info autoconf
