--- Comment #4 from Rainer Schuetze <r.sagita...@gmx.de> --- Posting C:\Users\Derik\Projects\TagIO\Projects\Library\Debug\Library.buildlog.html here might help. I suspect it might have to do with bad PATH settings. If you switch to mago as the debug engine used for debugging, no conversion to PDB will be necessary. It's actually the default now with the latest version of Visual D. --
