This chapter demonstrates the use of Sourcery G++ Lite from the command line. This chapter assumes you have installed Sourcery G++ Lite as described in Chapter 4, Installation and Configuration.
Table of Contents
This chapter explains how to build an application with Sourcery G++ Lite using the command line. As elsewhere in this manual, this section assumes that your target system is arm-none-linux-gnueabi, as indicated by the arm-none-linux-gnueabi command prefix.
Using an editor (such as notepad on Microsoft
Windows or vi on UNIX-like systems), create a
file named main.c
containing the following
simple factorial program:
#include <stdio.h> int factorial(int n) { if (n == 0) return 1; return n * factorial (n - 1); } int main () { int i; int n; for (i = 0; i < 10; ++i) { n = factorial (i); printf ("factorial(%d) = %d\n", i, n); } return 0; }
Compile and link this program using the command:
> arm-none-linux-gnueabi-gcc -o factorial main.c
There should be no output from the compiler. (If you are building a C++ application, instead of a C application, replace arm-none-linux-gnueabi-gcc with arm-none-linux-gnueabi-g++.)
