jcomp1

Usage

Overview

jcomp reads all the java-files specified on its command line, parses them as source code in a language which is a subset of the Java(tm) language, and generates a native binary in output-file.

Please note that jcomp internally makes use of bock(1), and is therefore not meant as a production compiler.

Options

Options must be given in tha same order they are described here, and before any java-files.

-O

Indicates that the C compiler's optimisation should be turned on.

-E

Indicates that the program should not be compiled into a binary; instead, the intermediate C code will be written to standard output.

-s

Specifies the name of the class whose main() function should be called when the program is run.

-o

Specifies which file to write generated native program to. If not specified, jcomp writes to the file j.out.

Files

/usr/share/bock/lib/*

A subset of the standard Java library, included automatically by jcomp.

Diagnostics

If jcomp detects an error or a construct it cannot compile, it writes a message to its standard error output and terminates with a non-zero exit code. There are many errors which jcomp does not detect.
