Using boost-program-options and native

Hey all!

I want to build a tool which makes use of boost-program-options lib. As long as I compile for the target, all is fine, but when I add
> BBCLASSEXTEND += "native"
to my recipe, I a bitbake error "Nothing Provides" ... :(

> ERROR: Required build target 'mytool-native' has no buildable providers.
> Missing or unbuildable dependency chain was: ['mytool-native', 'boost-program-options-native']

In the recipe I just depend on boost and RDEPEND on boost-program-options:
> DEPENDS = "boost"
> RDEPENDS_${PN} = "boost-program-options"

Is something wrong with this? Why is there a package boost-program-options but no boost-program-options-native, altough boost-native exists and the libboost-program-options.so is installed into the
native sysroot. (I can compile flawlessly without the RDEPENDS line.)

Any hints?

Cheers,
Thilo

Native and nativesdk flavors don't have packages, so RDEPENDS only works
when depending on ${PN}-native (but not for ${PN}-native-some-package). 

Try:

DEPENDS = "boost"
RDEPENDS_${PN}_class-target = "boost-program-options"

"boost" already is a dependency via DEPENDS, so you shouldn't need an
RDEPENDS for it in the native case.

The following worked for me when building a native recipe that depends
on Boost Program Options:

https://github.com/advancedtelematic/meta-updater/blob/morty/recipes-sota/sota-tools/sota-tools_git.bb

  inherit cmake
  DEPENDS = "boost ..."
  BBCLASSEXTEND = "native"

I'm no OE expect, so I won't claim this it is right answer, but it does
at least build.

Cheers,

Phil

Thanks for your answers!

The problem is, that boost_program_options is a library which needs to be installed on the target. This isn't done with DEPENDS boost only.

But the answer of Patrick Ohly worked for me. Now my package has a dependency to libboost-program-options1.60.0 in the control file!
