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 meth
ods.
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 suffix 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 dec
laration. 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 process
ing 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.
