SconsDynamicallyAddTargetToExecutor

Ссылки сюда (1) →

Consider the following situation.

• MainFile includes some GeneratedNN files (count of these files is unknown)
• All these GeneratedNN files generated by one Generator file (for example, python script).
• All these GeneratedNN files needed to be rescanned after generation (they can include other files).

I scan MainFile, and then I see inclusion of Generated1 file, I add something like this:

    cmd=env.Command(Generated1, Generator, RunMePlease)

But actually I need

    cmd=env.Command([Generated1,Generated2,…,GeneratedN], Generator, RunMePlease) 

but I must add targets incrementally during MainFile scan…

So the question is: How to dynamically add targets to Command? I try something like

Generator.executor.targets.append(env.fs.Entry(GeneratedN))

but it seems not working…
