Hello,
I have a problem defining a library dependency in the Makefile of a project.
- First of all I defined a Config.in file like so:
config MYPACKAGE_USES_LIBRARY
bool "Use library"
depends PACKAGE_mypackage && PACKAGE_mylib
default n
help
bla...
- included it in the Makefile:
...
define Package/mypackage/config
source "$(SOURCE)/Config.in"
endef
...
- added the package build dependency:
...
PKG_BUILD_DEPENDS:=MYPACKAGE_USES_LIBRARY:mylib
...
- and poke around now with the DEPENDS setting:
define Package/mypackage
...
DEPENDS:=CONFIG_MYPACKAGE_USES_LIBRARY:mylib
...
endef
I can toggle the bool on and off and the build includes or excludes the
library triggering the build beforehand or not.
If i now install the package on the target the dependency is not
recognized by opkg so mylib does not get
installed. If I omit DEPENDS:= that has the same result.
How can I configure the dependency of mypackage from mylib?
As I read in the mailing list the DEPENDS is scanned only if make
menuconfig is executed, what means the
MYPACKAGE_USES_LIBRARY is not set yet. Is that right?
When I toggle the setting and re-run make menuconfig there seems to be
made no re-scanning, therefore also
the dependencies are not updated. Is there a special package/rescan or
so target?
Thanks,
jan
