Eliminating these messages from the temporary m4 file being generated (which will not complete anyway) is sufficient for the rest of autoconf to complete, until it prints errors. In my case, the final error looks like: common/Makefile.am:20: error: Libtool library used but 'LIBTOOL' is = undefined common/Makefile.am:20: The usual way to define 'LIBTOOL' is to add = 'LT_INIT' common/Makefile.am:20: to 'configure.ac' and run 'aclocal' and = 'autoconf' again. common/Makefile.am:20: If 'LT_INIT' is in 'configure.ac', make sure common/Makefile.am:20: its definition is in aclocal's search path. autoreconf: automake failed with exit status: 1 But I've seen various reports for other root causes that ran into the = same problem (see bug report) Signed-off-by: Christophe de Dinechin <dinechin@HIDDEN> --- bin/autom4te.in | 2 ++ 1 file changed, 2 insertions(+) diff --git a/bin/autom4te.in b/bin/autom4te.in index 964ac1a..b3f3831 100644 --- a/bin/autom4te.in +++ b/bin/autom4te.in @@ -821,6 +821,8 @@ EOF my $traces =3D new Autom4te::XFile ($tcache . $req->id, "<"); while ($_ =3D $traces->getline) { + # Traces without file/line + next if (m{^m4trace: -(\d+)- ([^(]+)\((.*)$}); # Trace with arguments, as the example above.
