[Scons-users] How to create multiple tasks/jobs from a single builder invocation

[Matano, Rocco]

I have written a number of custom scons builders and I think I understand the basic concepts of those.

But now I am facing a task that I don't know how to solve. I would like to write a custom builder that takes
a list of source files and creates a single scons task / job for each source file, so that scons will work off
those tasks in parallel if '--jobs=N' was given on the command line.

When compiling C files like this

objs = env.Object(source=['file1.c', 'file2.c', 'file3.c', 'file4.c'])

that parallelism is achieved out of the box.

I would like to write a builder that also achieves that. I would like to be able to invoke that builder similarly:

targets = env.CustumBuilder(source=['file1.ext', 'file2.ext', 'file3.ext', 'file4.ext'])

So my question is:
What do I have to do when writing a custom builder in order to achieve that parallelism?

Regards,
Rocco
