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-eabi, as indicated by the arm-none-eabi command prefix.
Using an editor (such as notepad on Microsoft
Windows or vi on UNIX-like systems), create a
file named hello.c
containing the following
simple program:
#include <stdio.h> int main (void) { printf("Hello World!\n"); return 0; }
Compile and link this program using the command:
> arm-none-eabi-gcc -o hello hello.c -T script
Sourcery G++ requires that you specify a linker script with the
-T
option to build applications for bare-board targets.
Linker errors like undefined reference to `read'
are a symptom of failing to use an appropriate linker script.
Default linker scripts are provided in arm-none-eabi/lib
.
Refer to Chapter 6, CS3™: The CodeSourcery Common Startup Code Sequence for information
about the boards and linker scripts supported by Sourcery G++ Lite.
There should be no output from the compiler. (If you are building a C++ application, instead of a C application, replace arm-none-eabi-gcc with arm-none-eabi-g++.)
