2.1 Compiler command-line syntax

Use the armcc command from the command-line to invoke the compiler. Specify the source files you want to compile, together with any options you need to control compiler behavior.

The command for invoking the compiler is:

armcc [options] [source]



are compiler command-line options that affect the behavior of the compiler.


provides the filenames of one or more text files containing C or C++ source code. By default, the compiler looks for source files and creates output files in the current directory.

If a source file is an assembly file, that is, one with an extension of .s, the compiler activates the ARM assembler to process the source file.

When you invoke the compiler, you normally specify one or more source files. However, a minority of compiler command-line options do not require you to specify a source file. For example, armcc --version_number.

The compiler accepts one or more input files, for example:

armcc -c [options] input_file_1 ... input_file_n

Specifying a dash - for an input file causes the compiler to read from stdin. To specify that all subsequent arguments are treated as filenames, not as command switches, use the POSIX option --.

The -c option instructs the compiler to perform the compilation step, but not the link step.
