Using the Slice Compilers

Ice provides a separate Slice compiler for each language mapping, as shown below:

The Slice compilers.

The compilers share a similar command-line syntax:

<compiler-name> [options] file...

Regardless of which compiler you use, a number of command-line options are common to the compilers for any language mapping. (See the appropriate language mapping chapter for options that are specific to a particular language mapping.) The common command-line options are:

• -h, --help
  Displays a help message.

• -v, --version
  Displays the compiler version.

• -DNAME
  Defines the preprocessor symbol NAME.

• -DNAME=DEF
  Defines the preprocessor symbol NAME with the value DEF.

• -UNAME
  Undefines the preprocessor symbol {NAME.

• -IDIR
  Add the directory DIR to the search path for #include directives.

• -E
  Print the preprocessor output on stdout.

• --output-dir DIR
  Place the generated files into directory DIR.

• -d, --debug
  Print debug information showing the operation of the Slice parser.

• --ice
  Permit use of the normally reserved prefix Ice for identifiers. Use this option only when compiling the source code for the Ice run time.

• --underscore
  Permit use of underscores in Slice identifiers.

The Slice compilers permit you to compile more than a single source file, so you can compile several Slice definitions at once, for example:

slice2cpp -I. file1.ice file2.ice file3.ice
