Dear Shiewei,
I was trying to use and to check something in the source code of sudoDEM3D
However, I found that the program was distributed only in the form of
binary code. Did I miss something?
If not, could you please send me (or provide a link to download same
versions of) the source codes that were used to generate the binary objects
available as tarballs for sudoDEM3D at [1]
and for the third party libraries at [2]

I believe sudoDEM is a great achievement and I'm glad that yade was helpful
for that work.
I also think it is very important to comply to the terms and conditions of
yade's license (GPL2), and I feel annoyed that sudoDEM apparently doesn't.
In fact, it certainly also breaks the terms and conditions of some third
party libraries.

I'm reproducing below relevant subsets of yade's license (GPL2), they speak
for themselves I think. Please note that mentioning GPL3 on your website is
irrelevant since the GPL3 applies to a source code only, not to a binary
Licensing questions are not always easy, if you are unsure what is
permitted please contact, we will do our best
to advise.
If you are "in the process of" making sources available, then maybe just
don't distribute binaries meanwhile. In any case, make sure you can always
provide the exact same sources you use for generating each *.so you
The easiest (though not mandatory) way to do so, by far, is to
systematically give links to both binaries and sources for each version. In
any case, you must provide license in full, and a written notice on how to
get source codes if you don't provide a link to it.

Best Regards

Bruno Chareyre
