building statically linked java executables

[Bob Vandette]

There’s an option in newer JDKs "--enable-static-build” that was used
to build static libraries and generate single executable images for all the JDK tools
but it was only supported on MacOSX.  

The configure option —with-stdc++=static only affects the linking of the stdc++ library.

In JDK14/JDK15 there’s a new make target “static-libs-image” that can produce a set
of static libraries for some of the JDK libraries.  If you manually compile the java launcher and
link with these libraries, you’ll get close to what you want.  This make target only generates
a few of the JDK libraries but you could add to that list.

Bob.
