Thanks for replying. I've been trying to use Libtool as Bob hoped would be possible. I haven't studied the build system in WebAuth that you linked to in detail (or that in GraphicsMagick), but may do so if our current approach doesn't work out. > The key parts of this approach are: > > - Use Module::Build, not ExtUtils::MakeMaker.

In the current Texinfo "make distcheck" does a VPATH build, and works for me, at least (until we get a test failure due to different behaviour from the XS module). > - Let Perl handle its own compiler options and flags and only pass in > things discovered by Autoconf that you know you need.

It didn't seem that difficult really to replicate what ExtUtils::MakeMaker's Makefile did. One rule to generate a .c file from a .xs file, plus some CFLAGS and LDFLAGS obtained from the Perl "Config" module. http://svn.savannah.gnu.org/viewvc/trunk/tp/Texinfo/Convert/XSParagraph/Makefile.am?revision=6386&root=texinfo&view=markup Hopefully it doesn't rely on anything undocumented or unstable.
