Creating an Application

3.3 Building from the command line

This section describes how to build an application from the command line. From the

command line, you can access:

• the compilers (see Using the compilers from the command line)

• the CodeWarrior IDE (see Using the CodeWarrior IDE from the command line on

page 3-20)

• the debugger (see Invoking AXD from the command line on page 3-20)

• the assembler (see Using the assembler from the command line on page 3-16)

• the linker (see Setting linker options from the command line on page 3-17).

3.3.1 Using the compilers from the command line

There are four compiler variants as shown in Table 3-1:

Building an example

Sample C source code for a simple application is in

install_directory\Examples\embedded\embed\main.c

To build the example from the command line:

1. Compile the C file

main.c

with either:

armcc -g -O1 -c main.c

(for ARM)

tcc -g -O1 -c main.c

(for Thumb)

where:

-g

Tells the compiler to add debug tables.

-O1

Tells the compiler to select the best possible optimization while

maintaining an adequate debug view.

-c

Tells the compiler to compile only (not to link).
