I just downloaded the sources and startet to TRY to compile it. After identifiying a projectfile that looks promising I immediately run into my first (but probaly not my last ) problem.
I'm missing a project named SSR_server.dsp. Is this proprietary or was it forgotten to be included in the source distribution? I used the download of the sources and not the CVS access, but I guess I have to set this up, though I prefer to have a nightly update of the sources instead of CVS acces, because I can't access CVS everywhere.
