Problem: I'm on Ubuntu Cosmic (18.10). When attempting to build tinywl, I get several undefined reference's:

Dependencies

I installed wlroots via

meson build
ninja -C build
sudo ninja -C build install

and I seem to have all of the needed dependencies (in particular: wayland-scanner and other wayland libraries):

How Makefile variables are expanding

Just to be sure, I verified in a shell that the Makefile variables are expanding as follows: WAYLAND_PROTOCOLS := //usr/share/wayland-protocol, WAYLAND_SCANNER := /usr/bin/wayland-scannery, and finally LIBS := -I/usr/local/include -I/usr/include/libdrm -I/usr/include/pixman-1 -L/usr/local/lib/x86_64-linux-gnu -lwlroots -lwayland-server -lxkbcommon.

What gives?

Tinywl has improper gcc flag ordering. Its Makefile should be adjusted so that

tinywl: tinywl.c xdg-shell-protocol.h xdg-shell-protocol.c
        $(CC) $(CFLAGS) \
                -I /usr/include \
                -g -Werror -I. \
                -DWLR_USE_UNSTABLE \
                -o $@ $< \  # <-- this line switched with
                $(LIBS)      # <-- this line

and it now builds accordingly; however, there is a new error when running:

$ LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu ./tinywl 
2019-01-16 10:20:43 - [backend/session/direct-ipc.c:47] Do not have root privileges; cannot become DRM master

Tinywl should be choosing the X11 backend but instead it's choosing DRM. I tried opening ./tinywl on a tty with root privileges and it still fails; the error reads

Successfully loaded direct session

This seems wrong.

Is DISPLAY set in your env?

Yes:

$ echo $DISPLAY

Can confirm that the order works. See also https://eli.thegreenplace.net/2013/07/09/library-order-in-static-linking.

The linker first looks at tinywl.o for the symbols that it needs, then in -lwayland-server etc. It doesn't keep track of the symbols provided by preceding libs.

You're right. Can you send a PR?

This issue isn't completely fixed:

Tinywl should be choosing the X11 backend but instead it's choosing DRM.

Can you try rootston?

Never run a Wayland compositor with sudo.

Attempt to run rootston:

cd rootston
cp rootston.ini.example rootston.ini # I set `xwayland=true`
../build/rootston/rootston

@georgewsinger See https://github.com/swaywm/sway/wiki/Running-Sway-without-systemd
That page is not actually sway specific. It applies to any wlroots-based compositor, including rootston.

@ascent12 I'm running Unbuntu Cosmic 18.10, so should have systemd, no?

Do you mean this: https://github.com/swaywm/sway/wiki/Running-Sway-without-systemd#direct-via-capabilities ?

@georgewsinger You probably compiled wlroots without logind support. That would happen if you using the auto-detection of dependencies (the default behaviour) and you don't have libsystemd-dev installed.
Install that, run meson configure -Dlogind=enabled inside of the build directory to make absolutely sure, and run ninja again to recompile.

@ascent12 I'm now getting:

What I really need is the x11 backend enabled (I don't want to load tinywl in DRM, but in Ubuntu 18.10 against X). But when I adjust the meson.build file as follows to allow this:

conf_data.set10('WLR_HAS_LIBCAP', true)
conf_data.set10('WLR_HAS_SYSTEMD', true)
conf_data.set10('WLR_HAS_ELOGIND', true)
conf_data.set10('WLR_HAS_X11_BACKEND', true)
conf_data.set10('WLR_HAS_XWAYLAND', false)
conf_data.set10('WLR_HAS_XCB_ERRORS', false)
conf_data.set10('WLR_HAS_XCB_ICCCM', false)

I get this error:

But when I adjust the meson.build file as follows to allow this:

Don't do that, it won't work.

Instead, use Meson options: meson build -Dx11-backend=enabled.
