Oskar Liljeblad has made the first release of
gnome-gcj. This is a
project to create a complete set of Gtk+
and Gnome bindings for Java using
gcj.

Today we merged some major work done at Red Hat. This included:
- Substantial work for the IA-64 port.
- java.beans from Classpath.
- A somewhat modified initial implementation of serialization.
(This is known not to interoperate with other implementations yet.)
- Miscellaneous bug fixes.

Tom Tromey checked in the JNI stubs patch for gcj. This patch makes
it possible to use compiled Java code where the native methods are
implemented using JNI.

Warren Levy checked in a JDK 1.1 compatible version of
Classpath's java.sql.
Once we have merged the necessary JDK 1.2 support, we'll update
this to directly track Classpath.

message for some caveats.

Less recent GCJ news
|
GCJ is a portable, optimizing, ahead-of-time compiler for the Java
Programming Language. It can compile...
- Java source code to native machine code,
- Java source code to Java bytecode (class files),
- and Java bytecode to native machine code.
Before executing your compiled application, you must link it with
the GCJ runtime, libgcj, which consists of...
- the core class libraries,
- a garbage collector library,
- an abstraction over the system threads,
- and, optionally, a bytecode interpreter.
The addition of the bytecode interpreter means that GCJ compiled
applications can dynamically load and interpret class files, resulting
in mixed compiled/interpreted systems.
Compiled Java applications are debugged using recent versions of the
GNU debugger, GDB.
A short tutorial on using GDB to debug
GCJ-compiled applications is available.
In addition to regular native programming, GCJ can be configured as a
cross-compiler, suitable for embedded systems programming.
Gcj, libgcj, gdb and related tools are Free Software.
