Fist of all, you will need to write an implementation of the renderer
interface. As you are targetting hybrid postscript/latex output, I would
start with the current postscript renderer (app/render_eps.c).
You may be able to get it to do what you want by just modifying the single
function that handles drawing text.
After you have created the renderer, you want to create a DiaExportFilter
structure for your new filter. Take a look at the last 20 lines of
app/render_svg.c for ideas on this.
Then you want to add the plugin initialisation code, which should register
the export filter.
As for the makefile, make sure you are looking at Makefile.am (which is
quite simple) -- the Makefile is autogenerated by automake.
