Configuring Command-Line Tools. NXP CodeWarrior Development Studio

Chapter 2

Using Build Tools on the Command Line

CodeWarrior build tools may be invoked from the command-line. These command-line tools operate almost identically to their counterparts in an integrated development environment (IDE). CodeWarrior command-line compilers and assemblers translate source code files into object code files. CodeWarrior command-line linkers then combine one or more object code files to produce an executable image file, ready to load and execute on the target platform. Each command-line tool has options that you configure when you invoke the tool.

Configuring Command-Line Tools

Use environment variables on the host system to specify to the CodeWarrior command line tools where to find CodeWarrior files for compiling and linking. The table below describes these environment variables.

Table 2-1. Environment variables for CodeWarrior command-line tools

CWFolder

MWCIncludes

MWLibraries

The environment variable...

specifies this information

CodeWarrior installation path on the host system.

Directories on the host system for system header files for the

CodeWarrior compiler.

Directories on the host system for system libraries for the

CodeWarrior linker.

A system header file is a header file that is enclosed with the "<" and ">" characters in include directives. For example

#include <stdlib.h> /* stdlib.h system header. */

Typically, you define the

MWCIncludes

and

MWLibraries

environment variables to refer to the header files and libraries in the subdirectories of your CodeWarrior software.

To specify more than one directory for the

MWCIncludes

and

MWLibraries

variables, use the conventional separator for your host operating system command-line shell.

NOTE

CWFolder

environment variable specifies the CodeWarrior installation path on a host system. Verify the CodeWarrior installation path on the host system before setting the

CWFolder environment variable.
