Thank you both!

It seems to have worked.

However I got a new error.... (but later in the script)... And then I fixed that one too...

Seems the dh-translations was still missing... but now I have fixed it....

And managed to compile it!

I'm trying to find a good way to solve qtmir tests. For the test to work they need a lot of mocks that are based on internal mir stuff. And since they are used directly into mir it is not possible to build wrappers.

Include file	Object	test file	Defined in
mir/main_loop.h	mir::MainLoop	tests/framework/mock_main_loop.h	src/include/server/mir/main_loop.h
mir/scene/prompt_session.h	mir::scene::PromptSession	tests/framework/mock_prompt_session.h	src/include/server/mir/scene/prompt_session.h
mir/scene/surface.h>	mir::scene::Surface	tests/framework/mock_surface.h	src/include/server/mir/scene/surface.h
mir/shell/persistent_surface_store.h	mir::shell::PersistentSurfaceStore	tests/framework/mock_persistent_surface_store.h	src/include/server/mir/shell/persistent_surface_store.h
mir/scene/session.h	mir::scene::Session	tests/framework/mock_mir_session.h	src/include/server/mir/scene/session.h

So the best solution (or least bad) that I have come up with is...
to move all those mocks to miroil and make them accessible through a MockFactory... Something like:

class MockFactory
{
    auto get_mock_surface()                  -> std::shared_ptr<mir::scene::Surface>;
    auto get_mock_main_loop()                -> std::shared_ptr<mir::MainLoop>;
    auto get_mock_prompt_session()           -> std::shared_ptr<mir::scene::PromptSession>;
    auto get_mock_persistent_surface_store() -> std::shared_ptr<mir::shell::PersistentSurfaceStore>;
    auto get_mock_session()                  -> std::shared_ptr<mir::scene::Session>;    
    
    std::shared_ptr<mir::scene::Surface>                   surfaces;
    std::shared_ptr<mir::MainLoop>                         main_loops;
    std::shared_ptr<mir::scene::PromptSession>             prompt_sessions;
    std::shared_ptr<mir::shell::PersistentSurfaceStore>    persistent_surface_stores;
    std::shared_ptr<mir::scene::Session>                   sessions;       
};

The problem is that qtmir does not know the destructor of this objects, to they will have to be deleted inside miroil.
Therefore I have added a reference in MockFactor to the objects. Which are deleted by MockFactory. This will only work if MockFactory is the last object to be deleted, so we have to make sure it is.

So do you guys see any better solutions than this?

Hi!

I'm trying to get the crossbuilder working on the example in the documentation. But I'm stuck on an some thing to do with mk-build-deps??

So I'm using qemu/kvm running Ubuntu 18.04.3.... fresh install...

 crossbuilder setup-lxd
 cd ~/src/git/address-book-app

Then

  bash -x crossbuilder

a lot of output... but the last command is:

+ lxc exec address-book-app-usdk-16-04-amd64-armhf-dev -- sh -c 'mk-build-deps                 -t '\''apt-get -o Debug::pkgProblemResolver=yes --no-install-recommends -y'\''                 -i --host-arch armhf                 /home/demo/patched_debian_control'
