The top-level Makefile is generated by mangling rules, "a: b". We already avoid mangling "a := b". But we should also exclude "a = :".
Apparently this was causing unbalanced parenthesis errors on some systems. Reported-by: Mike Frysinger <[email protected]> Signed-off-by: Alan Jenkins <[email protected]> --- This version uses two separate rules, rather than resorting to "\?" which is ugly and not part of the POSIX regex spec. The patch applies to the module-init-tools tree. I assume Peter can use it as well though. diff --git a/m4/ax_enable_builddir.m4 b/m4/ax_enable_builddir.m4 index 49b3eb9..4273a53 100644 --- a/m4/ax_enable_builddir.m4 +++ b/m4/ax_enable_builddir.m4 @@ -187,8 +187,9 @@ s/^srcdir *=.*/srcdir = ./ s/^top_srcdir *=.*/top_srcdir = ./ /[[:=]]/!d /^\\./d -dnl Now handle rules (i.e. lines containing /:/ but not /:=/). -/:=/b +dnl Now handle rules (i.e. lines containing ":" but not " = "). +/ = /b +/ .= /b /:/!b s/:.*/:/ s/ / /g -- To unsubscribe from this list: send the line "unsubscribe linux-modules" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
