Hi all,
I am a little bit confused about how to correctly use dependencies in an openWRT feed makefile. There are several variables available:
DEPENDS
: If you say+package
that means if the current package is selected, it will causepackage
to be selected
DEPENDS
- (optional) Which packages must be built/installed before this package.
PKG_BUILD_DEPENDS
: Packages that need to be built before this package. UseDEPENDS
to establish the runtime dependencies.
EXTRA_DEPENDS
- (optional) Runtime dependencies. don't get built, only added to package
control
file
About build-time dependencies: If I use DEPENDS
I guess i do not need to use PKG_BUILD_DEPENDS
.
About run-time dependencies: Can I use the EXTRA_DEPENDS
variable for this? When I specify a package here, this package does not need to be build before my package, but it needs to be installed on the target.
EXTRA_DEPENDS
will probably not guarantee that this package is automatically selected in the menuconfig (like the DEPENDS
variable does)? I guess an error will be thrown when the makefile contains an EXTRA_DEPENDS
and this one is not selected by the user?
Thanks in advance for clearing this up.
