I've just completed a project using SDCC 2.8 on the mcs51 platform to control a model slot car drag strip, using interrupts based timers, LCD display, I/O floating point maths, etc. All 1700 lines of source, 19k of object code happily compiled running. Now I'm trying to creat a simple matrix display driver using an NXP P89V51RD2 prototype board from MindTek and I'm banging my head against a brick wall. After including the P89V51RD2.H header file and ever since, I keep getting SIGSEGV errors from the cpp. At one point when I had no includes, it just gave me errors that various SFR's were not defined but once the failure has occurred I can't seem to get anywhere. I upgraded from 2.8 to 2.9 last night and I still get the same problem but the last project still builds OK.
Any pointers would be great as I'm about to start writing it in assembler ! Graham Clinch
