I followed your Debian Installation Guide and the build went fine without error. That is, using #master repo from both wlc and sway. However, when I back out into TTY and attempt to run sway, I get the error in the title line. That is:

sway: symbol lookup error: sway: undefined symbol: wlc_set_pointer_motion_cb_v2

Since I did sudo make install on both sway and wlc as directed, chances are some dependency I installed via apt-get, or the #master versions of sway or wlc, do not match those at the time of the writing of Debian Installation Guide.

Debian GNU/Linux 9 (stretch)

Your wlc is outdated.

How? It just came from the master branch.

Unless it's picking up something from apt-get....let me see

You must have installed it incorrectly, maybe into /usr/local.

Here is the output after sudo make install of wlc:

Does /usr/include/wlc/wlc.h exist?

@brandon-arnold
Copy link
Author

Yes, it does.

@ddevault

Well, there you have it.

@brandon-arnold
Copy link
Author

I think I get it. So some other thing installed an older version, probably aptitude. Well I will have to figure out where that's coming from.

@brandon-arnold
Copy link
Author

Wait. No! What's wrong with it installing to /usr/loca/wlc? The output of sudo make install clearly states that it installed it there!

@brandon-arnold
Copy link
Author

I mean. Not my problem, right? I'm just following directions.

@ddevault
Copy link
Contributor

/usr takes precedence. You already installed it there before. You need to remove the old version from /usr or install the new version to /usr.

If the instructions are wrong, fix them. It's a wiki. Sway on Debian is user-supported.

Okay, thanks for the help.

@SirCmpwn I just removed the following files--my only guess is that I've tried installing this some time ago and forgotten:

usr
    ├── include
    │   └── wlc
    │       ├── defines.h
    │       ├── geometry.h
    │       ├── wlc.h
    │       ├── wlc-render.h
    │       └── wlc-wayland.h
    └── lib
        └── x86_64-linux-gnu
            ├── libwlc.so -> libwlc.so.0
            ├── libwlc.so.0 -> libwlc.so.0.0.9
            ├── libwlc.so.0.0.9
            └── pkgconfig
                └── wlc.pc

I've also verified that wlc installed to the location as per the output of sudo make install, above.

Why then is sway unable to find libwlc.so, as below?

brandon@goatboxter3:~/wlc-temp$ sway
sway: error while loading shared libraries: libwlc.so.0: cannot open shared object file: No such file or directory

@ddevault

If you're not going to install to /usr you need to set some environment variables to load libraries from somewhere else. Ask your distro for help.

Yep, I added a the *.so paths to my LD_LIBRARY_PATH in .bashrc and it seems to have picked them up. Now I'm getting the error as per #1162, as follows:

!! DANGER !! Sway does not have CAP_SYS_PTRACE and cannot enforce security rules for processes running as other users.

@ddevault

The error tells you what to do.

@brandon-arnold

I did it. Now I'm getting the damn missing .so file again. Sheesh!

@ddevault

For security reasons, sway clears your LD_LIBRARY_PATH from the environment during startup. You have to hard code it when you compile sway with cmake -DLD_LIBRARY_PATH=...

Alll right now we are cooking with grease. Let me try it.

Passing in a -D switch to CMake did not do it, but I was able to load it in system-wide via adding it to /etc/ld.so.conf. I feel like I am close but it is still not starting; here's the output after sway -d:

Maybe the config it copied over isn't working. I will fiddle with that.

Nope. Not sure! That I: 11/12/17 22:58:35 - [main.c:50] [wlc] Failed to open X11 display line must have something to do with it.

No, that doesn't have anything to do with it. I don't know what's wrong.

@SirCmpwn It turns out the problem is in trying to load the file in ~/.config/sway. Having removed the whole ~/.config/sway, the PPA as well as the AUR package for Arch are working. When I have time I will look over Sway/source/doc to see how the experience may be improved for idiots such as myself.
