This is the first release of Flex Builder to support Desktop Linux. This version is based on several features from Flex Builder 3 (codenamed “Moxie”). It includes project creation, code coloring, code hints, compilation, the Ajax Bridge, Find All References, and debugging. Not all Flex Builder 3 features are supported, so be sure to check out the release notes for a list of unsupported features.

FAQ

Is Flex Builder for Linux part of the Flex 3 beta?

No. Adobe is developing the Linux product in parallel with Flex 3. Many of the Flex 3 features are also included in the Linux version, however the Linux product is a separate project and is on its own schedule.

Are all of the Flex Builder 3 features included in the Linux release?

No. Although many of the features in Flex 3 are included in the Linux release, there are several features that are not yet included. Our main goal is to get the base features in place and then to solicit user feedback and their priorities for additional features, such as the profiler or design view. For a list of the features currently included in the alpha release, please read the release notes.

When will Flex Builder for Linux be fully released?

Adobe has not yet announced a release date for the Flex Builder Linux product. In part, this will be determined by user feedback on the required features, so if you have requests be sure to file them in the bug database.

Where can I download the Flex Builder Linux alpha?

You can download the public alpha from Adobe Labs.

Will you be charging for Flex Builder Linux at some point?

How do I get Data Visualization Charting Components for Linux?

While the Data Visualization and Charting components are not part of the Flex Builder Linux Alpha, it is possible to purchase a Flex Builder 3 Professional license (either Mac or Win) – and move the licensed datavisualization.swc file over to your Linux installation. This process has been explained by various users in our forums and is acceptable under the terms of your Flex Builder 3 license.
