Normally, this would work

SYNOPSIS

[-add text] [-append text] [-friend text]
[-preprend text]
[--classpath=path] [--CLASSPATH=path]

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
implementation 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.
-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
-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 processing is done.
-v, --verbose
Print extra information while running.
All remaining options are considered to be names of classes.
