`npm run start:native` and `npm run start` fail with "That operation is not supported"

[joshmhanson]

System: Ubuntu 18.04. Note that I happen to have an OCaml compiler installed (the BuckleScript version), but this shouldn't make a difference.

All three build commands worked fine, but the two of the three start commands are not working, as you can see below.

start:native

$ npm run start:native

Appreciate any help!

[Schmavery]

Do any of the executables exist in the lib folder? ex: lib/bs/native/index.native or lib/bs/bytecode/indexhot.byte?
If so, I'm guessing you get the same result when invoking those binaries directly (taking npm out of the equation)?

[joshmhanson]

Yep that's correct. When attempting to run the files directly, I got the plain "operation not supported" error without all the surrounding npm-generated noise.

[joshmhanson]

To follow up on this: I tried it on a different computer (also Ubuntu 18.04) but one that didn't have OCaml installed. I made a fresh install of ReasonML and followed the exact instructions for the reprocessing-example.

This time, I got almost exactly the same result except that the error is different. Under Wayland, it would say "wayland not available", and underxorg, it says that there's no graphics device available.

[Schmavery]

Hmm, thanks for following up. The issue with an existing ocaml install might be something @bsansouci is interested in for bsb-native, whereas the graphics device issue seems like more complications with how we're building sdl2 on linux (which has ended up being very picky).

You can see we've tried to fix this a couple of different ways (Schmavery/reprocessing#74 (comment)) but it looks like there's something we've overlooked, so thanks for pointing it out! Likely we will need as much of your help as we can get to help debug it as we're pretty much guessing when it comes to some of this linux configuration stuff.

We do this hack to try and detect and enable wayland support: bsansouci/reasongl@e664d18
but maybe it isn't getting detected properly on your machine. Can you try setting the environment variable SDL_VIDEODRIVER=wayland manually before running the reprocessing binary? If we're lucky, that will work.

If that doesn't work and you want to fiddle with how we invoke the configure command for building sdl2, you can find that here: https://github.com/bsansouci/SDL-mirror/blob/fast/postinstall.js#L74

cc @zploskey fwiw as he was invaluable last time we had issues like this (in case you're interested)

[zploskey]

I just ran through the basic build process for this repo at a46f1e0 on Ubuntu 18.04 running Xorg. It does not deal well with having an ocaml compiler in the path (at least not the 4.06.1 opam switch I was on), complaining about a DLL. Once I removed my opam binaries from the path, though, everything built fine and I was able to run them demo for both bytecode and native.

I would suggest perhaps installing the same packages that we pull in to run the Travis build: https://github.com/Schmavery/reprocessing/blob/master/.travis.yml

sudo apt install libsdl2-dev fcitx-libs-dev libibus-1.0-dev

I have these installed and it works. I think the goal is to be able to build without having to manually install additional packages, so we may need to work on making sure we install all required dependencies in one way or another. I've said before I don't think Linux users would mind having to install their system SDL library rather than building it ourselves as long as its spelled out in the instructions. Currently I think we're missing some required dependencies on Linux.

[Schmavery]

Thanks for trying it on your machine! If that's what it takes, we can definitely add a note about that and then potentially look into fixing it

[joshmhanson]

Thanks for your feedback @Schmavery and @zploskey.

I did try it again quickly this morning with the SDL_VIDEODRIVER=wayland and this did not change anything under Wayland.

Regarding having OCaml in the path, I originally had OCaml 4.07 installed and encountered the same Fatal error: cannot load shared library dllunix issue as was experienced in #8. I opam switched to the BuckleScript fork of the OCaml compiler, which resolved this particular issue on the machine where I had OCaml installed.

I'll also note that opam 2.0 supports local switches so this should hypothetically make it possible to work around the global OCaml installation issue by having a local OCaml switch set to the BuckleScript fork. I haven't tested this yet.

When I get the chance I will make another attempt after installing the dependencies you mention above on both my system with OCaml and my system without OCaml. (By the way, libsdl2-dev is unsurprising, but why fcitx and ibus?)

[zploskey]

Feel free to try it without fcitx and/or ibus and see if you have any issues. That list came out of some experimentation when setting up TravisCI for Reprocessing.

[Schmavery]

Yeah by all means let us know if some of those aren't required haha

[joshmhanson]

You were right: SDL2 wasn't enough. sudo apt install libsdl2-dev fcitx-libs-dev libibus-1.0-dev and then rebuilding reprocessing was necessary to get it working in both native and bytecode. At some point I will attempt testing a local opam switch as well.

[Schmavery]

@hanjiexi for now, I added a note to the reprocessing repo that linux users may need those deps. Thanks for following up.

[crakoucas]

Same error - Ubuntu 18.10 - Gnome - Wayland
Fatal error: exception Failure("Unknown error while loading plugin: Failure(\"wayland not available\")")
Works well under Ubuntu 18.10 - Gnome - Xorg

[Schmavery]

@crakoucas sorry to hear that, can you give a couple more details and let us know what happens when you try the debugging steps above?

[crakoucas]

I Follow the Readme for the install with

sudo apt install libsdl2-dev fcitx-libs-dev libibus-1.0-dev

Everything works fine on Ubuntu 18.10 Opengl but in Wayland =>

[bsansouci]

@crakoucas Thanks for the debug info. Do you have the WAYLAND_DISPLAY env variable set to something? We'd added this hack to fix Wayland support but it might not be reliable. Can you try setting SDL_VIDEODRIVER=wayland before running the executable?
Does this also happen in native?

Alternatively do you have XDG_SESSION_TYPE set to anything?
