2 Command-Line Options

You can specify command-line options to the aCC command. They allow you to override

the default actions of the compiler. Each option begins with either a - or a + sign. Any

number of options can be interspersed anywhere in the aCC command and they are

typically separated by blanks. Unless specified otherwise, all options are supported by

C and C++ compilers.

Default options can be set using option configuration files. See “Configuration Files

(.conf Files)” (page 32).
