Free native software for linux

JavaNativeCompiler (JNC) is a Java to native compiler. The project allows AOT (ahead of time) compilation of your Java applications. With JNC, you can create real standalone native binaries (.exe on Windows) which will no longer depend on a JRE.
This is especially useful when applications have to be deployed to end-users. All vexatious problems of deploying Java applications can be solved by compiling them to native. They will be:
- Easy to deploy
No JRE dependency. Most end-users dont know what they have installed.
No more problems on how to create an executable file out of a JAR or class file.
- Hard to decompile
Java can easily be decompiled. Native compilation will protect your source code.
- Run fast from the start
No more overhead for loading a JRE.
Enhancements:
- This release fixes a couple of problems with AWT/Swing and XML.
- It also once again contains a version for Linux.
- The compiler binary downloads are smaller.

Banteng is a cross platform visual javascript for building native desktop applications on Windows, Linux, and Mac OS X.

The 0.1.1 release includes the core runtime engine and some basic examples.

Math::ODE Perl module allows you to solve N-th Order Ordinary Differential Equations with as little pain as possible.

Currently, only IVPs (initial value problems) are supported, but native support for BVPs (boundary value problems) may be added in the future. To solve N-th order equations, you must first turn it into a system of N first order equations, as in MATLAB.

Conserver is an application that allows multiple users to watch a serial console at the same time. Conserver project can log the data, allows users to take write-access of a console (one at a time), and has a variety of bells and whistles to accentuate that basic functionality.
The idea is that conserver will log all your serial traffic so you can go back and review why something crashed, look at changes (if done on the console), or tie the console logs into a monitoring system (just watch the logfiles it creates).
With multi-user capabilities you can work on equipment with others, mentor, train, etc. It also does all that client-server stuff so that, assuming you have a network connection, you can interact with any of the equipment from home or wherever.
Heres a list of systems that Ive been told can successfully compile conserver. If anyone has more to add to this list (or something on the list doesnt work any more), please let me know.

Jaune project is a Java-like compiler for small systems.
Jaune is a compiler and set of libraries that can be used to write programs in the Java language for small devices.
It includes a basic set of class libraries, garbage collector, and set of examples that can be run on the Nintendo GameBoy.
Main features:
- All of the object-oriented features of the Java language.
- A conservative, compiler directed garbage collector.
- Sufficient base class support for implementing most of the niceties of the Java libraries.
- Native implementations of the Object, String and StringBuffer classes for speed.
- A very straight forward native code interface.

Sol Manager is a tool to manage your source files and configuration settings. SolMgr organizes project information in compiler- and platform-independent descriptions and allows conversion to native build scripts, such as makefiles or MS Visual Studio solutions.

GUI is provided to visually control project configurations, and to perform everyday project management tasks such as files addition/removal, dependency management etc.

Notice: SolMgr is under heavy development currently, so it lacks many features and functionality.

Baghira is a native style for QT/KDE.

The name refers to the Panther of Kiplings famous Jungle Book (German spelling)

You will probably rather know the Disney version...

Basically its a perky imitation of Apples OSX look.

Installation:

tar -xjf baghira.tar.bz2
cd baghira/baghira
./configure --prefix=`kde-config --prefix` --disable-debug [--enable-final]
(!!!BEGINNERS: the direction of the accents is _important_ (top-left to bottom-right), the rectangular brackets mean [this is optional] - dont type them!!!)
make
and finally as root:
make install

Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.
