Hi! After changing 'configure.in', 'acconfig.h' or 'acinclude.m4' you should run $ aclocal; autoheader; autoconf; automake I suggest that you do this on squark because it has newer versions of autoconf and automake. After changing one of the 'Makefile.am' files you should run $ automake; ./config.status at the top level (i.e. the directory where 'configure.in' lies). 'automake' will generate the 'Makefile.in's and 'config.status' will recreate the Makefiles according to your last configuration (this assumes that you didn't change 'configure.in' or did a 'make distclean' in which case you must re-run 'configure'). These should be the only configuration-related files which you can edit. Bye, Christian -- / Coding on PowerPC and proud of it \/ http://www.uni-mainz.de/~bauec002/
