Andrei,
Since the perplex/re2c/lemon setup is a bit obtuse from a build system
perspective (which is my fault primarily) I've taken your patch and
adapted it to give you what should be a minimal working setup. The
attached patch, applied to the top level of a clean BRL-CAD trunk
checkout, should result in a src/conv/csg setup that will build.
Applying it to a tree with your existing csg work won't work - it must
be applied to a clean checkout. Study it carefully to see if it makes
sense, and note the changes I made to the CMakeLists.txt file and the
perplex/lemon inputs. If you want to see the details of what commands
it is running to build the various intermediate files, use make
VERBOSE=1 to build.
>From this starting point, if you want to pursue this approach a bit
further, the next step is to make this do something simple. I haven't
altered any of the logic - this is just to try to get you over the
build system hurdles and started with the important bit - the csg
logic. Don't try to preserve all the complexities of what is in the
perplex and lemon files now. Sean's suggestion of a simple adder
would be a good starting point.
