tools:在ubuntu 20.04上搭建weston環境

參考:

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,主要問題集中於第五步編譯:

  1. 某些git庫已經不需要【協議庫】
  2. 缺少pkgconfig的path
  3. 某些源碼需要meson/ninja編譯
  4. libxfont需要打patch
    maze@maze-VirtualBox:~/Wayland/libXfont$ git diff ./
    diff --git a/configure.ac b/configure.ac
    index e497325..f71ca0c 100644
    --- a/configure.ac
    +++ b/configure.ac
    @@ -54,6 +54,9 @@ AC_CHECK_HEADERS([endian.h poll.h sys/poll.h])
     AC_CHECK_FUNCS([poll readlink])
     AC_SEARCH_LIBS([strlcat], [bsd])
     AC_CONFIG_LIBOBJ_DIR([src/util])
    +if test "$ac_cv_search_strlcat" = "-lbsd"; then
    +  AC_DEFINE(HAVE_LIBBSD,1,[Has libbsd])
    +fi
     AC_REPLACE_FUNCS([reallocarray realpath strlcat strlcpy])
     
     # Check for BSDish err.h
    

     

  5. 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
    

     

 

 

可以參考我的編譯時用到的patch

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

隨後weston還需要weston.ini放到~/.config/

至此,weston能夠啓動
