Hi Florian,
this does not answer my question, I asked about PKG_BUILD_DEPENDS, not DEPENDS!
Defining the dependencies between packages is not the problem.
My problem is an application, that can manage two different chips via their
drivers.
To build the application I need the sources of the driver unpacked/installed
before compiling,
to include the interface definition of the driver.
For a single driver it is no problem to define
PKG_BUILD_DEPENDS:=driver_x
But if I can select a second driver and define
PKG_BUILD_DEPENDS:=driver_x driver_y
both drivers gets unpacked and built (which is not what I want, but would be a
workaround!).
You can try the same with ppp and libpcap (which is only listed as
build-dependency!)
If I do the definition like described in my first mail, no build-dependency is
defined,
as the config-options are not known during package-scan (which is correct in
general).
Maybe you have an idea, how to restrict the build-dependencies to the selected
packages.
Currently updating to kamikaze/trunk is not an option, even if it might be
fixed there.
Hoping for another hint,
Thomas
