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 26).
