I got the files - just in case I want to make use of them one day. Not really. I checked that the iu folder was in the src folder (it is); and I checked your options against what's in my batch file (they agreed). I therefore feel as confident as a noob can be. The compile is under way, up to Compiling src/drivers/volfied.c If an error occurred, does it get written to a log? Does it cause the compile to stop - or does it carry on?
