ProjectCenter is GNUstep's integrated development environment (IDE). It assists you in starting new projects and lets you manage your project files using a intuitive and well ordered graphical user interface. ProjectCenter automatically creates the project makefiles and aids you in the process of editing, project compilation, package building, and debugging.
ProjectCenter and Linux
ProjectCenter is running on any system which has support for GNUstep. While there are some issues on non x86 platforms related to Objective-C and GNUstep, there are no reasons why ProjectCenter should not run on any other GNUstep aware system.
