Having a continuous integration system is an essential component of software development:
Continuous Integration Process
This system requires automating the building process.
The LabVIEW development environment unfortunately does not have built-in tools to achieve this easily.
But the community has supplied a few sollutions to achieve this: CLI Tool
On of the biggest hurdles that yet remain, is the fact that the application builder is inherently tied to the development environment.
This requires a valid license for the environment and all toolkits / technologies used in the source code of the product you intend to build.
My proposal would be to have a special "CI" license in which all required modules and toolkits are activated, and that would allow the development environment to launch in some sort of protected mode that prevents users from actively developping code (while still allowing scripting functions), for the sole purpose of building applications.
