tools:在ubuntu 20.04上搭建weston環境

參考：

https://wayland.pages.freedesktop.org/weston/index.html

https://wayland.freedesktop.org/building.html

https://github.com/wayland-project/wayland-build-tools

1.git clone https://github.com/wayland-project/wayland-build-tools

Step 1: Install git, and clone the wayland-build-tools repository

        apt-get install -y git
        git clone git://anongit.freedesktop.org/wayland/wayland-build-tools

Where you place this repository is up to you.

Step 2: Prepare expected directories

        mkdir ~/Wayland # sources and builds will be here
        mkdir -p ~/.config/wayland-build-tools
        cp wl_defines.sh ~/.config/wayland-build-tools/

You can change these directories if you wish, but these are the defaults
and you'll need to edit the scripts to match. See WL_ROOT and WLD in
wl_defines.sh.

Step 3: Install packaged build dependencies

        ./wl_install_deps

Step 4: Clone the necessary repositories

        ./wl_clone

Step 5: Build upstream dependencies, Wayland, and Weston

        ./wl_build

Step 6: Run Weston

        source ~/.config/wayland-build-tools/wl_defines.sh
        weston

如 Readme，主要問題集中于第五步編譯：

某些git庫已經不需要【協定庫】
缺少pkgconfig的path
某些源碼需要meson/ninja編譯

libxfont需要打patch [已經更新，不再需要]

編譯weston需要安裝各種庫

sudo apt-get install libpipewire-0.2
sudo apt-get install libgstreamer1.0
sudo apt-get install libcolord-dev
sudo apt-get install liblcms2-dev
sudo apt-get install libva-dev
sudo apt-get install libsystemd-dev
sudo apt-get install libwebp-dev
sudo apt-get install libjpeg-dev


sudo ln -s /usr/lib/x86_64-linux-gnu/libffi.so.7 /usr/lib/x86_64-linux-gnu/libffi.so.6

NOTE Xwayland的部分可以不編譯！

可以參考我的編譯時用到的patch

編譯成功後，運作weston，需要把libweston-9.so.0與libweston-desktop-9.so.0放到usr/lib/

sudo ln -s ~/Wayland/install/lib/x86_64-linux-gnu/libweston-9.so.0 /usr/lib/libweston-9.so.0
sudo ln -s ~/Wayland/install/lib/x86_64-linux-gnu/libweston-desktop-9.so.0 /usr/lib/libweston-desktop-9.so.0

随後weston還需要weston.ini放到~/.config/ [目前沒有weston.ini也能啟動weston,并且預設的backend是x11-backend]

至此，weston能夠啟動

tools:在ubuntu 20.04上搭建weston環境

基于最新weston 9.09的最新修改如下：

./weston-launch -u root -t /dev/tty8
