Announcing Dryverl: an Erlang-to-C binding compiler

[Richard A. O'Keefe]

I downloaded dryverl-0.1 from the ObjectWeb site.
gzcat ...tar.gz | tar xvf -
cd dryverl-0.1
./configure --prefix=/users/local
make
...

./examples/hello_build is empty.
There is no ./examples/hello_build/hello/configure,
but there _is_ an examples/hello/configure
I think the line
    hello_build && cd hello_build && ./hello/configure && \
should be
    hello_build && cd hello_build && ../hello/configure && \
                                     ^^

Looking at examples/Makefile, it is quite hard to see what is going on.
I can't quite see where $(srcdir) is set, but wherever it is set, it
is wrong for this example.  Patching the corresponding line of the Makefile
to use ../hello/configure instead of $(srcdir)/hello/configure gets a long
way further.

By the way, six languages in one tool is a little overwhelming.
It would be much simpler for bears of very little brain if interfacing
between Erlang and C only required them to know Erlang, C, and maybe
*one* more notation.
