SDCC is a small Device C Compiler that was specifically designed to the needs of 8 Bit Micros like Intel 8051, Maxim 80DS390, Zilog Z80 among others. SDCC comes with SDCDB a source level debugger and ucSim a free open source simulator for Intel 8051 and other micro-controllers

Installation

Debian

apt-get install sdcc

Working with SDCC

Compiling a program

Write this in an ASCII editor and call the archive test.c (Or wathever name you want):

char test;
void main(void) {
   test=0;
}

Then:

sdcc -c test.c

The -c option is for disable the linker, the next step is trying without the linker:

sdcc test.c

Final test, modify the test file and include the following (if all goes without warnings SDCC is well instaled):

#include <string.h>
char str1[10];
void main(void) {
 strcpy(str1, "testing");
}

this is needed to test that SDCC supports libraries.
