This sounds wrong. The content of the lib/ directory is

There is a mix of shared libraries (only things which should be here), executable binaries (which should go to ${bindir}), source files (which shouldn't be in the tarball at all), files I have no idea what they are (*.wad and *.pk3) and static library (it's ok to have the static library in ${libdir}, but that's just useless for the purpose of calling a library from Julia, so we usually avoid having static libraries around).

[jbrea]

Thanks. I removed most files, but vizdoom.pk3 and freedoom2.wad seem to be needed. Otherwise games won't load.

The build system assumes you can run executables built for the target platform, which we can't. This is very cross-compilation-unfriendly.

[jbrea]

Thanks for the review!

Can I fix this somehow? Note that I use the flag -DCMAKE_CROSSCOMPILING=FALSE, because I couldn't resolve some cmake errors otherwise. But I don't really understand its implications.

Well, we are cross-compiling, so that's a blatant lie 🙂

[jbrea]

Btw. To actually use ViZDoom_jll I have the following lines in ViZDoom.jl

module ViZDoom

using CxxWrap
using ViZDoom_jll

@wrapmodule("libvizdoomjl")

function __init__()
    @initcxx
end

include("util.jl")
export get_scenario_path, set_game

include("games/games.jl")
export basic_game

end # module

Now, when I actually want to run a game I get

~/.julia/artifacts/01f94640f8ea8b00edc310b9f24899fa7811a6ca/lib/vizdoom: error while loading shared libraries: libboost_thread.so.1.76.0: cannot open shared object file: No such file or directory

unless I set my LD_LIBRARY_PATH to the artifact containing libboost 1.76.0. Is there an alternative to setting the LD_LIBRARY_PATH in ViZDoom.jl?

I also get occasionally and seemingly at random the error

C++ exception while wrapping module ViZDoom: invalid subtyping in definition of Label with supertype Any
ERROR: InitError: invalid subtyping in definition of Label with supertype Any
during initialization of module ViZDoom

Don't know if this is related.

How are you running the program?

[giordano]

Side note: I quickly skimmed through CMake files of ViZDoom and there are some references to cross-compilation. It sounds like they should support it, but I have no idea how they want to do it. I also don't really have the time to dig into this, so if you want to target all platforms you'll have to do some investigations on your own.

[jbrea]

How are you running the program?

In a Julia REPL,

julia> using ViZDoom

julia> game = basic_game()

julia> ViZDoom.init(game)

[giordano]

I wanted to know how you're running the executable. I have no idea what basic_game() and ViZDoom.init(game) do.
