Hi Ted,<br>
<br>
the cbc package itself builds fine and I think the examples too.
That Cgl-related problem is to link own code.<br>
<br>
Moreover, in MSVC 2013 it works. Under Linux I had to downgrade Cbc
to 2258 to resume it working.<br>

BUILD.sh as a template to switch on compilation of the module using
