Hi all, Just got my REAL ICE, and trying out a debug build of a hello world PIC32 program with it. The debug configuration won't build. This is the error I get: ---------------------------------------------------------------------- Debug build of project `E:\Projects\PIC32\HelloWorld\HelloWorld32.mcp' started. Language tool versions: pic32-ar.exe v2.01, pic32-gcc.exe v2.01, pic32-ld.exe v2.01, pic32-ar.exe v2.01 Preprocessor symbol `__DEBUG' is defined. Target debug platform is `__MPLAB_DEBUGGER_REAL_ICE=3D1'. Debug platform options are: `__ICD2RAM=3D1'.
