Hello,
I would like to abort the evaluation of a make script
if data processing was requested for a target which does
not support a parallel software build process so far.
I do not want to use the .NOTPARALLEL pseudo-target for
some of my applications when I can call a make function
like error on

There are programming interfaces available which

more powerful computer systems.
I imagine that the software jobserver could
be extended for the convenient reuse of such APIs.

So I try to reuse a corresponding system setting by a command

A bit of build preparation needs to be performed

So I need to be flexible with the specification of input and
output parameters for these programs. But I see some software
development challenges for this use case.
I'm sorry but I don't really understand what you're trying to do.
How do you think about to share any more software
Jobserver is a method of communicating how many jobs make thinks are
running between different instances (parent/child) of the make
program itself, so it knows that no more than N jobs are invoked
between all instances.
How do you think about to delegate such an implementation detail
to a

I assume that you want something different from this
but you need to explain better, sorry :-)
I hope that an other wording will be clearer.
Can make rules be extended on demand while a build script
is evaluated?
How much can a command like getconf _NPROCESSORS_ONLN
influence rule evaluation

It seems like you want to automatically expand or contract the
number of jobs that make will run in parallel,
Yes, exactly.
I can not use the parameter -j directly for the start of the main
make process in my case so far.

So you have in your toolbox $(shell) and $(eval).
I am not familiar enough with the second make function.
http://www.gnu.org/software/make/manual/html_node/Eval-Function.html
$(eval) lets you generate rules dynamically.
Does it really support the generation of completely new build rules

There are two completely separate things: one thing is make deciding
how many jobs can be run in parallel and when more jobs can be started.
Thanks for your explanation.
That's controlled by the jobserver and currently there's no
way to replace the built-in jobserver implementation with

I guess I don't really see what the purpose of this is. If you have 2
CPUs you get targets MYTARGET_0 and MYTARGET_1. If you have 4 CPUs you
get targets MYTARGET_0, MYTARGET_1, MYTARGET_2, MYTARGET_3.
So... then what?
I need to find some source files before I can start further processes
The corresponding processes should be efficiently started for
parallel background execution after a serial data preparation
was finished.
This makes very little sense.
This issue depends on work flow ordering.
In a properly written Makefile, your serial preparation step
will remain
