Got a legacy 16F616 project written in Hi-Tech PICC, that needs some=20 development. The old MPLAB IDE it was created on is trapped in a broken Win partition. I'm using a working MPLAB 8.89 on a separate PC. A full-spec purchased PICC compiler (v9.70) was found on the broken PC. I tried downloading picc-lite to the working MPLAB initially, but it=20 didn't support 16F616 in its "do not edit" .ini file, so I'm aiming to=20 get the full compiler working. I've copied across the old PICC 9.70 compiler folder and done my best to=20 set it up in "Set Language Tool Locations". The code almost compiles, giving me the following: Clean: Deleting intermediary and output files. Clean: Deleted file "C:\\.cce". Clean: Done. Executing: "C:\HI-TECH Software\PICC\9.70\bin\picc.exe" -C -E".cc= e" ".c" -O".obj" -Zg9 -O -ASMLIST -Q -MPLAB -16F616 (924) missing argument to "-O" option Halting build on first failure as requested. BUILD FAILED: Fri May 24 11:12:44 2013 If this is a familiar problem then I'd be grateful to hear from you.
