Compiling the code

[RChadwick7]

How do you compile the code? I assumed SDCC, but running the makefile caused errors. Do I need an older version of SDCC?

Have you figured out how to compile the code? I'm using a windows sdcc-3.8.0-x64 and I'm getting errors:

C:>sdcc C:\specan\specan.c

In file included from C:\specan\specan.c:22:
C:\specan/display.h:58:1: warning: "NOP" redefined

No, I never figured it out. Hopefully someone has, as the in-me is an ideal platform for quickly developing ideas.

I got it to compile without errors but have not tried to flash it. You need to use an older SDCC version, I believe it compiles with versions 2.9, 3.0, 3.1, 3.4, 3.5, 3.6 but the compiled file doesn't match the compiled file that the author made. That makes it a bit scary for me. Maybe its because I'm using windows version of SDCC and author used Linux version, or maybe a sub version that i cant find like 3.0.2 or ???

After compiling it with 2.9.0 #5416 (Mar 22 2009) (MINGW32) it did flash it without problems.

so when i received this error i check out all the files containing the putchar and i removed all reference from C:/Program Files/SDCC/bin/../include/stdio.h and it compiled no problem you could also just remove the reference from display.h
