Did a previous information fit to this expectation already?

I am curious if involved communication difficulties can be resolved
better by other means.

I assume that you got used to the handling of specific file suffixes
also for their application together with make scripts.

One part of the discussed software documentation deals with
the combination of compilation and further source code analysis,
doesn't it?


> Julia, Markus- can you tell me how to run coccicheck on one source file?

You can choose between two methods.

* Use the documented build target with appropriate parameters.
  (How many Linux software modules do consist of only a single source file?)

* Do you get further ideas from another concrete command example?
