NAME gcjh - generate header files from Java class files

SYNOPSIS gcjh [-stubs] [-jni] [-force] [-old] [-trace] [-J option] [-add text] [-append text] [-friend text] [-preprend text] [--classpath=path] [--CLASSPATH=path] [--bootclasspath=path] [-Idir...] [-d dir...] [-o file] [-td dir] [-M] [-MM] [-MD] [-MMD] [--version] [--help] [-v] [--verbose] classname...

DESCRIPTION The "gcjh" program is used to generate header files from class files. It can generate both CNI and JNI header files, as well as stub imple- mentation files which can be used as a basis for implementing the required native methods.

OPTIONS -stubs This causes "gcjh" to generate stub files instead of header files. By default the stub file will be named after the class, with a suf- fix of .cc. In JNI mode, the default output file will have the suffix .c.

-jni This tells "gcjh" to generate a JNI header or stub. By default, CNI headers are generated.

-force This option forces "gcjh" to write the output file.

-old This option is accepted but ignored for compatibility.

-trace This option is accepted but ignored for compatibility.

-J option This option is accepted but ignored for compatibility.

-add text Inserts text into the class body. This is ignored in JNI mode.

-append text Inserts text into the header file after the class declaration. This is ignored in JNI mode.

-friend text Inserts text into the class as a "friend" declaration. This is ignored in JNI mode.

-prepend text Inserts text into the header file before the class declaration. This is ignored in JNI mode.

--classpath=path --CLASSPATH=path --bootclasspath=path -Idirectory -d directory -o file These options are all identical to the corresponding gcj options.

-o file Sets the output file name. This cannot be used if there is more than one class on the command line.

-td directory Sets the name of the directory to use for temporary files.

-M Print all dependencies to stdout; suppress ordinary output.

-MM Print non-system dependencies to stdout; suppress ordinary output.

-MD Print all dependencies to stdout.

-MMD Print non-system dependencies to stdout.

--help Print help about "gcjh" and exit. No further processing is done.

--version Print version information for "gcjh" and exit. No further process- ing is done.

-v, --verbose Print extra information while running.

All remaining options are considered to be names of classes.
