Jaguar v2.1 is released as several components. This includes the Jaguar code tree itself, the two back ends (OpenJIT-Jaguar and GCJ-Jaguar), and various utilities.

• Jaguar v2.1 Distribution: Get the file

  jaguar-20000517.tar.gz (gzipped tar file, 186 Kb).

  This contains the entire Jaguar v2.1 code tree. Compilation and installation instructions are found in the Jaguar Installation Guide.

• You must also choose one of the back-end compilers. OpenJIT-Jaguar is a Jaguar-enabled JIT that works with various operating systems and JVM's. GCJ-Jaguar is a static Java compiler which produces very fast code but does not support the full range of Java libraries (yet!).

  OpenJIT-Jaguar Back-end Compiler: Get the file

  OpenJIT-Jaguar-1.1.10.tar.gz (gzipped tar file, 148 Kb).

  You may also obtain a newer version of OpenJIT from the OpenJIT web site and use these instead. If you do this you will need to patch these trees with patches contained in the Jaguar release; see the installation guide for details.

  GCJ-Jaguar Back-end Compiler: Get the files

  gcc-2.95.2-jaguar.tar.gz (gzipped tar file, 13.1 Mb)
  libgcj-2.95.2.tar.gz (gzipped tar file, 2.3 Mb)

  These are the source trees for the GCJ Java compiler and LIBGCJ runtime library, modified to support compilation of Jaguar bytecode.

  If you are running a recent x86 Red Hat Linux system, you can try to use my precompiled snapshot of GCJ-Jaguar instead:

  gcj-2.95.2-jaguar-x86.tar.gz (gzipped tar file, 10.5 Mb).

  You must unpack this into the directory /usr/local/ninja (it will create the directory egcs-jaguar below that point). This is because the installed pathname is compiled in. This is mostly meant as a time-saver; ideally you should compile this for yourself.

  You may also obtain a newer version of the GCJ and LIBGCJ trees from the GCJ web site and use these instead. If you do this you will need to patch these trees with patches contained in the Jaguar release; see the installation guide for details.

• (Optional) GDB 4.18 with Java and Linux Threads Support: Get the file

  gdb-4.18-4.i386.rpm (Red Hat RPM, 782 Kb).

  This is entirely optional, and provides a version of GDB which allows you to debug Java programs compiled with GCJ. Instructions are found in the Jaguar User Guide. Note that Red Hat version 6.1 and later already has an approprate version of GDB installed.
