在YOCTO Kirkstone为i.MX6编译WPEBackend-rdk时遇Wayland构建错误

编译报错 #

Could NOT find Wayland (missing: WAYLAND_INCLUDE_DIRS)

变量状态 #

为空的变量 #

• WAYLAND_INCLUDE_DIRS
• WAYLAND_CFLAGS
• WAYLAND_CFLAGS_OTHER
• WAYLAND_LDFLAGS_OTHER

已赋值的变量 #

• WAYLAND_FOUND: 1
• WAYLAND_LIBRARIES: wayland-client;wayland-server
• WAYLAND_LINK_LIBRARIES: /[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib/libwayland-client.so;/[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib/libwayland-server.so
• WAYLAND_LIBRARY_DIRS: [build_folders]/work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib
• WAYLAND_LDFLAGS: -L/[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib;-lwayland-client;-lwayland-server

已知配置 #

• PREFERRED_PROVIDER_virtual/wpebackend = "wpebackend-rdk"
• 使用配方：wpebackend-rdk_1.20221201.bb
• 源码分支：master

解决步骤 #

1. 补全Wayland依赖并重建 #

确保wpebackend-rdk_1.20221201.bb中添加完整的Wayland依赖：

DEPENDS += "wayland wayland-native"

若已添加，清理Wayland构建缓存后重新构建：

bitbake -c cleansstate wayland
bitbake wayland

2. 手动传入CMake变量 #

在配方中强制指定Wayland头文件路径和编译参数：

EXTRA_OECMAKE += " \
    -DWAYLAND_INCLUDE_DIRS=${RECIPE_SYSROOT}/usr/include \
    -DWAYLAND_CFLAGS=-I${RECIPE_SYSROOT}/usr/include \
"

3. 验证Sysroot完整性 #

检查${RECIPE_SYSROOT}/usr/include/wayland目录是否存在，且包含wayland-client.h等核心头文件。若缺失，说明Wayland包未正确安装，需排查Wayland自身配方的构建日志。

4. 指定CMake模块路径 #

若WPEBackend-rdk的CMake无法找到Wayland模块，在配方中添加模块路径：

EXTRA_OECMAKE += " \
    -DCMAKE_MODULE_PATH=${RECIPE_SYSROOT}/usr/share/cmake/Modules \
"

5. 切换适配分支 #

master分支可能与Kirkstone的CMake版本兼容性不佳，尝试切换到对应版本的稳定分支：

SRC_URI = "git://github.com/WebPlatformForEmbedded/WPEBackend-rdk.git;branch=1.20221201"
