embedded-linux - 在 pkg-config 搜索路径中找不到软件包 xkbcommon。构建 Yocto 图像时

Question

在 Ubuntu 14.04 上

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty

使用 fido 分支构建一个 Yocto Poky 图像

inherit core-image
IMAGE_FEATURES += "x11-base x11-sato package-management ssh-server-dropbear"
IMAGE_INSTALL += "chromium \
                  lsb \
                  kernel-modules \
                  alsa-utils \

...我收到了这样的消息

我看起来它与 Chromium 配方 /meta-browser/recipes-browser/chromium/chromium_45.0.2454.85.bb 相关

include chromium.inc

DESCRIPTION = "Chromium browser"
DEPENDS += "libgnome-keyring"

我收到这条消息

ERROR: Logfile of failure stored in: /home/joel/yocto/build-fido/tmp/work/cortexa7hf-vfp-vfpv4-neon-poky-linux-gnueabi/chromium/45.0.2454.85-r0/temp/log.do_configure.28622

我尝试过的

安装库

$ sudo apt-get install libxkbcommon-x11-dev

搜索xkbcommon.pc

$ apt-file search xkbcommon.pc
libxkbcommon-dev: /usr/lib/x86_64-linux-gnu/pkgconfig/xkbcommon.pc

包配置

joel@linux-Lenovo-G50-70:~/yocto/build-fido$ pkg-config --cflags xkbcommon
               <=== Return is EMPTY (?)
joel@linux-Lenovo-G50-70:~/yocto/build-fido$ pkg-config --libs xkbcommon
-lxkbcommon    <=== Looks correct

添加了PKG_CONFIG_PATH

 $ PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib/x86_64-linux-gnu/pkgconfig/
 $ export PKG_CONFIG_PATH


 $ env | grep PKG
 PKG_CONFIG_PATH=:/usr/lib/x86_64-linux-gnu/pkgconfig/

但我在运行 bitbake 时仍然收到相同的消息

有什么建议吗？

找到xkbcommon

$ find /usr/lib/ -name *xkbcommon*
/usr/lib/x86_64-linux-gnu/libxkbcommon.so
/usr/lib/x86_64-linux-gnu/libxkbcommon.so.0.0.0
/usr/lib/x86_64-linux-gnu/libxkbcommon-x11.so.0.0.0
/usr/lib/x86_64-linux-gnu/libxkbcommon-x11.a
/usr/lib/x86_64-linux-gnu/libxkbcommon.a
/usr/lib/x86_64-linux-gnu/libxkbcommon-x11.so.0
/usr/lib/x86_64-linux-gnu/libxkbcommon-x11.so
/usr/lib/x86_64-linux-gnu/pkgconfig/xkbcommon.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/xkbcommon-x11.pc
/usr/lib/x86_64-linux-gnu/libxkbcommon.so.0

Answer 1

在这种情况下，是 Chrome 配方未能找到 libxkbcommon。由于在为目标系统构建配方时发生错误，我们需要告诉构建系统 Chrome 配方依赖于 libxkbcommmon。

这可以通过添加

 DEPENDS += "libxkbcommon"

Chrome 配方。

值得注意的是，libxkbcommon 很可能是一个可选的依赖项，在这种情况下，它应该由合适的 PACKAGECONFIG 处理。 (参见 PACKAGECONFIG in ref.manual)。

Note: I've never built chromium myself, thus I'd prefer to not suggest any suitable PACKAGECONFIG.
