C and C++ Compilers

Specifying keyboard input

Use minus – as the source filename to instruct the compiler to take input from the

keyboard. Input is terminated by entering

Ctrl-D

on UNIX environments or

Ctrl-Z

MS Windows environments.

An assembly listing for the keyboard input is sent to the output stream after input has

been terminated if both of the following are true:

• no output file is specified

• no preprocessor-only option is specified, for example

-E

If you specify an output file with the

-o

option, an object file is written. If you specify

the

-E

option, the preprocessor output is sent to the output stream.

Getting help and version information

Use the

-help

option to view a summary of the main compiler command-line options.

Use the

-vsn

option to display the version string for the compiler.

Redirecting errors

Use the

-errors

filename

option to redirect compiler error output to a file. Errors on the

command line are not redirected.
