Description Denis 2018-06-12 15:19:41 UTC

Hello.

I tried to build mesa with fix from this ticket https://bugs.freedesktop.org/show_bug.cgi?id=106861, and it failed with this error:


configure: error: Package requirements (wayland-egl-backend >= 3) were not met:

No package 'wayland-egl-backend' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables WAYLAND_EGL_CFLAGS
and WAYLAND_EGL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
Makefile:648: recipe for target 'config.status' failed
make: *** [config.status] Error 1

Checked on:
HEAD is now at 3c288da drivers/dri/i965: add missing #include

Comment 1 Denis 2018-06-12 15:20:54 UTC

./autogen.sh --with-egl-platforms=x11,wayland --with-gallium-drivers="" --with-dri-drivers=i965 --enable-debug

that's how I configured mesa

You need to install a newer version of the core Wayland repository, which now provides libwayland-egl.

Comment 3 Sergii Romantsov 2018-06-13 05:51:38 UTC

Sorry, Daniel, but have objection.

You have mentioned that packet libwayland-egl has to be used.

On site https://packages.ubuntu.com/search?keywords=wayland said that packet libwayland-egl is provided by libwayland-egl1-mesa.
I have libwayland-egl1-mesa and also libwayland-dev installed.

But they both don't have nor package wayland-egl-backend nor header wayland-egl-backend.h (see libwayland-dev_installedFiles.png and libwayland-egl1-mesa_installedFiles.png)

So proposed patch is https://patchwork.freedesktop.org/patch/229080/

Sorry, didn't realise at once your words "core Wayland repository".

If that means that user has to make Wayland manually or upgrade system to the 18.10 because of lack just only one header, than seems its not issue...

Comment 7 Timo Aaltonen 2018-06-13 13:35:59 UTC

such is life, 16.04 won't get a newer wayland, but 18.04 will.. eventually

for now, you can use a ppa for a backport with the necessary packaging changes:
