Renaissance—A Cross-Platform Development Tool for Linux and Mac OS X

Prepare to move to a Linux desktop by writing your apps with this flexible framework now.

We use the same file for both GNUstep and Mac OS X. Under GNUstep, modify the GNUmakefile to add instructions so that our translation resource gets installed. The following two lines need to be added to the GNUmakefile: TiffViewer_LOCALIZED_RESOURCE_FILES = ... and TiffViewer_LANGUAGES = ....

Finally, under GNUstep, recompile the application in order to copy the resource file properly and launch it using its French translation, like this:

# make
# openapp -NSLanguages '(French)'

On Mac OS X, you also have to create the French.lproj directory and the Localizable.strings file (or reuse the ones created for GNUstep) with the content shown in Listing 5. Once they have been created, follow these steps to activate the French localization in Project Builder:

  1. Select the Resources node and from the Project menu, choose Add Files... and add the French.lproj/Localizable.strings file.

  2. From the Build menu, click on Build.

To run the application in French under Mac OS X, from the System Preferences, click on the International icon. Then, drag Français before English and quit the application. From Project Builder's Debug menu, click on Run Executable. The application should start in French.


The Renaissance framework provides valuable innovations to help develop truly portable applications. Eventually, Renaissance will have a complete graphical editor, allowing you to create gsmarkup files graphically, as you can do now with Gorm, the Graphical Object Relationship Modeler for GNUstep, or with Interface Builder under Mac OS X.

In a future GNUstep article, we will enhance our simple TIFF viewer application to work with the GNUstep Database Library (GDL), an excellent free implementation of the NeXT's Enterprise Objects Framework (EOF).

Has somebody worked with these application development tools?
It seems they have solutions for Linux but I wanted to know if somebody has experience with any of the tools

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
