Your workaround only works if you build in-tree, i.e., if you do non-VPATH builds. If we stick to leaving generated files out of the git repo, we should make the testsuite pass with the range of tools that our build system allows. That is, we currently have AC_PREREQ([2.59]) ... AM_INIT_AUTOMAKE([1.7.9 ...]) and we require m4 >= 1.4.5 (unless $M4 is set). So either we make the above strict enough so that the current test suite passes, or write a bootstrap script that does a self-bootstrap, or refuse to run the test suite without a regeneration, or we relax the test suite. We definitely (well, at least me) don't want even more noise due to false failure reports. For this, it would help if you posted those spurious test failures. This is what I found with a casual check: 2.59 is not sufficient, but Automake 1.7.9 seems to be. I'll applied the patch below, if nobody disagrees. FWIW, with m4 1.4.5, test 125 (Define a newline) fails due to the changed error line number reporting of m4: | -configure.ac:5: warning: AC_DEFINE: `one | -configure.ac:5: two' is not a valid preprocessor define value | +configure.ac:6: warning: AC_DEFINE: `one | +configure.ac:6: two' is not a valid preprocessor define value Thanks, Ralf 2007-11-02 Ralf Wildenhues <Ralf.Wildenhues@xxxxxx> * configure.ac (AC_PREREQ): Require version 2.60, for AC_PROG_SED, AC_PROG_GREP. diff --git a/configure.ac b/configure.ac index 4f9a71e..3a79310 100644 --- a/configure.ac +++ b/configure.ac @@ -17,8 +17,8 @@ # You should have received a copy of the GNU General Public License # along with this program.
