Thanks for the general philosophy on how to accomplish this task, it's much needed. I have several questions though, I understand how to set the libs flag, LIBS="$LIBS -lreadline -lhistory" however, I can't simply set the -I and -L flags because the path is relative to the current build directory, right? Is there a way to get the absolute path to the $srcdir/readline-5.0 in the configure.in, so that I can simply say -I$ABSOLUTE_srcdir/readline-5.0 -L$ABSOLUTE_srcdir/readline-5.0? or do I have to have each Makefile.am specify the relatvie path back to $srcdir/readline-5.0, and only if the internal readline is chosen? BTW, what's the appropriate way to set the CFLAGS, CPPFLAGS and LDFLAGS? This is what I have been doing, LDFLAGS="-L$opt_with_readline_prefix/lib $LDFLAGS" CFLAGS="-I$opt_with_readline_prefix/include -I$opt_with_readline_prefix/include/readline $CFLAGS" CPPFLAGS="-I$opt_with_readline_prefix/include -I$opt_with_readline_prefix/include/readline $CPPFLAGS" Thanks for the much needed help, Bob Rossi _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
