This option is an alternative to using @code{--main}; you cannot use both.

|

@item -static-libgcj
|
||||
This option causes linking to be done against a static version of the
|
||||
libgcj runtime library. This option is only available if
|
||||
corresponding linker support exists.
|
||||
|
||||
@strong{Caution:} Static linking of libgcj may cause essential parts
|
||||
of libgcj to be omitted. Some parts of libgcj use reflection to load
|
||||
classes at runtime. Since the linker does not see these references at
|
||||
link time, it can omit the referred to classes. The result is usually
|
||||
(but not always) a @code{ClassNotFoundException} being thrown at
|
||||
runtime. Caution must be used when using this option. For more
|
||||
details see:
