Free application development environment software for linux

Java Development Environment for Emacs (JDEE) is an Emacs-based integrated development environment (IDE) for developing Java applications and applets.
Features include multiple code browsers, a JPDA-based debugger, method and field completion, template-based and procedure-based code generation, Java source code interpreter, context-sensitive help, and more.
Enhancements:
- On XEmacs, Use efc-xemacs-query-options, i.e., a GUI dialog box instead of a text dialog box, only if use-dialog-box is nonnil.
- Fixes bug in ProjectClasses to avoid duplicate entries of imports.
- Updated JDEEs Ant interface to force use of pipes to interact with external Ant process.
- Fixed regression that caused jde-help-class-member to issue a Lisp error.
- Fixed regression in jde-wiz-update-class-list command.
- Fixed regression that caused JDEbug to issue a Lisp error when launching an application.
- Thanks to Martin Schwamberger.
- Revise the following templates to conform to CheckStyle requirements:
- jde-gen-deep-clone-template
- jde-gen-to-string-method-template
- jde-gen-bean-template
- Thanks to Martin Schwamberger.
- Added the following code generation templates:
- jde-gen-exception
- Generates an exception class in the current buffer.
- jde-gen-exception-buffer
- Generates a buffer containing an exception class.
- jde-gen-hashcode-method
- Generates a hashcode method at point.
- jde-gen-equals-method
- Generates an equals method at point.
- jde-gen-tostring-method
- Generates a toString method that uses Apaches
- ToStringBuilder class.
- Thanks to Ole Arndt.
- Enhanced jde-run-option-classpath to allow you to specify that the JDEE should omit the classpath argument when running the class or application in the current buffer, regardless of the setting of jde-global-classpath.
- Fixed regression that caused the JDEE to switch projects during debugging when stepping into code that does not belong to the project being debugged.
- Updated regular expressions used by the JDEEs interface to jdb to accommodate non-English punctuation styles for numeric expressions in debugger messages, e.g.,
- 1.200 for a line number where the English would write 1,200.
- Thanks to Morten B. Isaksen.
- In previous releases, building javadoc caused all future uses of compilation mode to try to
- display the javadoc. This release fixes the problem.
- Thanks to David Evers.
- Updated the submit-problem-report command to include an XEmacs users init.el file.

CDK4AVR stands for Cross Development Kit for Atmels AVR RISC processor serie and should support your development with a comprehensive Assembler and C development environment for even this processor familie under Linux. It will present only free of fee tools, so you can use it without risks. Further you will find some useful OS projects and related sample code all arround AVRs inside of the example packages.
CDK4AVR collects all programms and development tools in one directory (/opt/cdk4avr) and will try to present an easy to admin installation.
My intention for CDK4AVR is / was to provide a full featurd tool chain distribution of all the free accessible resources, because the most stuff is scattered to the wide of the whole Internet and only compileable by wizards or professions.
Installation:
Each package will be provided as RPM only. It is not necessary to install all packages,but you have to install the base package cdk-avr-base every time you want to use another package. Here is an example for a typical GNU development environment:
[user@host]$ rpm -hiv cdk-avr-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hiv cdk-avr-binutils-2.14-20030906.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-c++-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-gcc-colorgcc-3.3.2-20031021.i386.rpm
[user@host]$ rpm -hiv cdk-avr-libc-1.0.2-20040229.noarch.rpm
[user@host]$ rpm -hiv cdk-avr-gdb-6.0-20031019.i386.rpm
[user@host]$ rpm -hiv cdk-avr-simulavr-0.1.2.20040304cvs-20040304.i386.rpm
[user@host]$ rpm -hiv cdk-avr-avarice-2.2-20040229.i386.rpm
[user@host]$ rpm -hiv cdk-avr-uisp-20040207cvs-20040304.i386.rpm
[user@host]$ rpm -hiv cdk-avr-avrdude-4.3.0-20040229.i386.rpm
Base package -- is needed every time you will use any CDK4AVR package.
NOTE: Users of base packages with version 0.2 and prior have to update to latest version. There was a damaged (t)csh startup script. As a result of an buggy %preun script in previous packages you have to update in two cycles:
[user@host]$ rpm -hUv cdk-nios-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hUv --force cdk-nios-base-0.3-20031111.i386.rpm
Enhancements:
- There are minor feature enhancements in AVR-Ada 0.4.1.
- As a result, the packeges for binutils and gcc/gnat were rebuilt.
- There are new packages for the AVR-Ada run time system and related examples.

Lucidium Application Platform project consists of a platform for the rapid and agile delivery of custom data/process application
ucidium is an application development environment in which fully featured, custom, Web-based data/process solutions can be delivered using little or no code. After describing your data model to the platform, it will automatically create powerful search, list, review, and update screens.
Skins can be customized using XSL, and complex actions can be added using JavaScript or Java. Any relational data model and process can be described and delivered.
Available ERP type modules include HR, Accounts, Logistics, Project Management, Case Log, and Document Management.
Main features:
- A platform upon which data driven applications can be configured and deployed.
- Cuts development cost, risk, complexity and effort.
- Is a proven open-source Java solution.

PHP_Application project is a platform for development of event-driven applications in which two mechanisms of distribution of events for two levels of abstraction accordingly are realized. The first level are objects and their events, the second - the application and its events.
The mechanism of distribution of events of the applications supports distribution of the directed and broadcasting events, and also provides synchronous or asynchronous processing events.
The structure of the application represents hierarchy of objects with various levels of abstraction. Functionality of the application is completely defined by a set of the objects included in the application, and interaction between them, i.e. a stream of events. The used structure of the application allows to operate a stream of events extending downwards on hierarchy of objects.
PHP_Application includes, also, two interchangeable libraries: HTML Component Library (HCL) and XML Component Library (XCL) which use, accordingly, HTML Template Engine and XSLT Processor for generation of page. Thus, the application can be adjusted easily for use of this or that way of generation of page.
To additional features PHP_Application concern: multilanguage support; the ability to control access of object properties; multilevel access to the data of tabulared and tree-like type and many other things.
Enhancements:
- In the new version support of Aspect-Oriented programming is added;
- the rendering system is refactored;
- many new classes are added;
- new examples and the documentation are added;
- many bugs are corrected.

Nemesis Utilities System or NUS for short, is a cross-platform C++ application development framework that focuses on the development of network applications, non-GUI applications, CGI scripts, database applications, and any kind of application that needs interoperability.
NUS is very modular, making it easy to maintain, debug, and deploy. The project was greatly inspired by other libraries such as Trolltechs Qt.
Enhancements:
- A security module with hash manipulation classes was added.
- A class to manipulate command-line options was added.
- The output handling classes were improved.
- Exception handling was improved.
- The XML module was documented.
- The examples were improved.

libnetshclient is a POSIX/ANSI C library for use in the development of applications that require direct communication (using the netsh protocol) with a Foxmoxie Networks STRATA-family router (or any server-type-application that supports the protocol).
libnetshclient library employs both IPv4 and IPv6, as well as GnuTLS encryption.
Enhancements:
- TLS support, managed connections, bugfixes and improvements

ProjectCenter is GNUsteps integrated developement environment (IDE). It is based in part on NeXTs original Project Builder. It assists you in starting new projects and lets you manage your project files using a intuitive and well ordered graphical user interface.

Serg Stoyan is the current maintainer of ProjectCenter. Please contact him if you would like to submit a bug report or volunteer to improve ProjectCenter. The original author of ProjectCenter, Philippe C.D. Robert, no longer actively contributes to the application.

Over a decade ago, NeXT Computer Inc. revolutionized application development by making two great developer tools available for their operation system OPENSTEP: Project Builder and Interface Builder. These applications made application development much easier and faster and took NeXT ahead of the other computer manufacturers and operating system vendors.

Supporting the project types Application, Bundle, Library, Tool, and Aggregate, ProjectCenter automatically creates the project makefiles and aids you in the process of editing, project compilation, package building and debugging. In the future, built-in CVS support will be available, too.

ProjectCenter is a very useable application, but is still evolving. Support is there for project creation and inspection as well as basic Makefile generation. Using the Application project type, you can already create graphical applications using ProjectCenter and Gorm in conjunction.

GNUstep is a free, standard, object-oriented, cross-platform development environment meant to provide generalized visual interface design, a cohesive user interface, and look good as well. GNUstep is based on and completely compatible with the OpenStep specification developed by NeXT (now Apple Computer Inc.).
GNUstep is a whole load of things, but primarily a framework (libraries, tools, applications) for developing software. It is not a not a window manager. And the libraries are not used by WindowMaker at present, although WindowMaker shares a similar look.

At no stage will you ever run GNUstep - you will run applications and tools and will make use of its services. At some point you may well find packages distributed as GNUstep systems in the way that you get GNU/Linux systems packaged today. Look at Simply GNUstep, the GNUstep Live CD, and Project Backbone for examples.

The ProjectCenter will hopefully consist of the following capabilities somewhen in the midterm future:

* Project management
This includes versioning control, automatic makefile generation, file management etc.

* Source code editing facilities
A builtin editor will be available in a future release. This has not main priority, though.

* Debugging fascilities
A builtin debugger will be added to ProjectCenter as soon as possible!

* Documentation automation help
Automatic documentation generation using autogsdoc or another tool will be introduced later.

* UML-based case tool
