config FREETZ_PACKAGE_JAMVM bool "JamVM 1.4.4 (binary only)" select FREETZ_PACKAGE_CLASSPATH select FREETZ_LIB_libffi default n help JamVM - extremely small Java VM JamVM is a new Java Virtual Machine which conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~160K, and Intel 140K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, Soft/Weak/Phantom References, class-unloading, the Java Native Interface (JNI) and the Reflection API. Class Libraries: JamVM is designed to use the GNU Classpath Java class library. A number of classes are reference classes which must be modified for a particular VM. These are provided along with JamVM (see INSTALL). JamVM should always work with the latest development snapshot of Classpath (currently 0.93). It should also work with the latest version direct from CVS, and the upcoming 0.94 snapshot (but check the Classpath mailing lists for possible patches). Later snapshots of Classpath may also work, if no modifications have been made to the VM interface. Note, JamVM will not work with the class library from Sun or IBM's Virtual Machines. # Include here a cleaner menu structure source make/classpath/Config.in config FREETZ_LIB_libffi bool "ffi-sable (libffi.so)" requires FREETZ_PACKAGE_JAMVM help libffi is a library that really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages. ffi stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. NOTE: At the moment, this library is only used by JamVM. If any other package should need it, the fixed dependency can be removed and the library be put into the general library section of menuconfig.
