Perhaps its not really helping you, but I think that to really understand cdbs
it helps to consider what is under the hood.
If you look at the files that we include with the usual statements, those in
the /usr/share/cdbs/1/ directories, you will see that these are the usual
makefiles, and contain no less/no more than:
1) a list of specific variables, that might be used from debian/rules to
control the behaviour of cdbs
2) a list of rules, which are automatically called at appropriate steps
What these rules will do depends on the specifics, but in general they will:
- check some pre-requisites or variables
- call a number of debhelper scripts
For instance, if you check the /usr/share/cdbs/1/rules/debhelper.mk file, you
A list of variables, first general, second specific to this makefile.
You will find some very good comments about what each of these variables will
contain and usually the effect they will have. Suppose that you have a
problem with the way cdbs calls dh_shlibdeps for a certain foo package in
your source package. By looking at the list you will find a nice variable,
DEB_DH_SHLIBDEPS_ARGS_foo, that you can use to pass specific argument to this
call which will hopefully solve your problem.
After this, you will basically find a general purpose debian/rules, a bit like
what dh_make will make, but with a logic already implemented.
