Hi Jow,
With the bool depends option I meant the option itself only to be
displayed if mylib was selected to be built. That indeed created a
recursive dependency.
After some trial-and-error I finally was able to realize the desired
configuration by moving depends PACKAGE_mylib to the
Package/myPackage/config section (Note that I intended "option" to be
visible only if library is selected and not to let option select
library). It also was possible to remove the PKG_BUILD_DEPENDS as
suggested before.
Thanks jow, for the support.
FYI: The config now looks like that:
define Package/myPackage
...
DEPENDS:MYPACKAGE_USES_LIBRARY:myLib
...
endef
define Package/myPackage/config
source "$(SOURCE)/Config.in"
depends on PACKAGE_myPackage && PACKAGE_myLib #[1]
endef
[1] moving this line up into Config.in or even before the source ""...
line seems to link the dependency to myPackage rather than to the option
itself - that might be the circular dependency...
and:
config MYPACKAGE_USES_LIBRARY
bool "use library"
default n
help
bla...
Result:
- "use library" option only visible if myPackage AND myLib are used
- if not selected build without library features and without linking
library
- if selected build library beforehand, compile features and link
library as well as add opkg dependency
