We need to be sure that it covers current make targets like make swigify which generate the c wrappers from swig interface files (we run this before checkins). Also make test needs to work. Also there is no top level ./configure so this won't let you build the entire repo. I'd like something (even if it was just the makefile that ran ./configure in each dir. I also get a failure: [root@misterfreeze libsepol]# autoreconf -iv autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force configure.ac:17: installing `./compile' configure.ac:6: installing `./install-sh' configure.ac:6: installing `./missing' include/Makefile.am:2: whitespace following trailing backslash include/Makefile.am:5: whitespace following trailing backslash include/Makefile.am:8: whitespace following trailing backslash include/Makefile.am:9: whitespace following trailing backslash include/Makefile.am:11: whitespace following trailing backslash include/Makefile.am:14: whitespace following trailing backslash include/Makefile.am:20: whitespace following trailing backslash src/Makefile.am:10: Libtool library used but `LIBTOOL' is undefined src/Makefile.am:10: The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL' src/Makefile.am:10: to `configure.ac' and run `aclocal' and `autoconf' again. src/Makefile.am:10: If `AC_PROG_LIBTOOL' is in `configure.ac', make sure src/Makefile.am:10: its definition is in aclocal's search path. src/Makefile.am: installing `./depcomp' Makefile.am: installing `./INSTALL' Makefile.am: required file `./NEWS' not found Makefile.am: required file `./README' not found Makefile.am: required file `./AUTHORS' not found autoreconf: automake failed with exit status: 1 -- This message was distributed to subscribers of the selinux mailing list.
