Hi all,
I want to read out the prerequisites of a defined target into a variable
but outside the target rule. Within the target rule I can access to it via
$$+, but how can I get this value from outside?
The other thing I'm trying to solve is:
make without any arguments builds my targets (and this works fine)
make clean should clean up my output targets and their compiled
prerequisites - like doing a rollback in a database and name the files that
have to be removed
Basically I could solve that by writing rm *.o and so on.
What I have is a dynamically built target list and a dynamically created
prerequisite list based on variables that are built when executing the
standard "make" call.
There is all information for doing a "clean" present it is only hidden in
the dynamically created rules and I have currently no idea how to access them.
My idea was to just read out the rules and remove the targets and their
prerequisite files (finally with rm).
Finally I'm looking for a possibility that prevents that new prerequisites
get appended to a target.
You can write
target: prerequisiteN
as often as you want but how can I "close" the list of prerequisites so
that there cannot be appended anything else? (or that all successive
appended prerequistes are ignored)
Lots of questions :-)
Thanks a lot in advance!
Best regards,
Erik
