如何使用元工具链-qt5 构建 Qt(支持 QtWebEngine)?

问题描述

我正在尝试使用 meta-toolchain-qt5 构建 Qt，但是当我通过 poky-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-vfp-vfpv4- 执行此操作时neon-toolchain-2.0.1.s‌ ‌ h，我在 sysroot 目录中没有看到有关 QtWebEngine 的任何内容.

我也尝试使用以下命令构建 Qt

bitbake meta-toolchain-qt5

但结果是一样的；我对 Qt WebEngine 一无所知.

如何使用 QtWebEngine 支持构建 Qt?

解决方案

看meta-toolchain-qt5，它继承了populate_sdk_qt5，反过来又增加了packagegroup-qt5-toolchain-target 到 SDK.仔细查看packagegroup-qt5-toolchain-target，发现包组不直接包含qtwebengine.因此，如果 packagegroup-qt5-toolchain-target 中没有其他内容拖入 qtwebengine 作为依赖项，qtwebengine 将不会被安装.>

如果你在packagegroup-qt5-toolchain-target的RDEPENDS_${PN}中添加qtwebengine，你会得到相关的qtwebengine 包.

I am trying to build Qt using meta-toolchain-qt5, but when I do this via poky-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-vfp-vfpv4-neon-toolchain-2.0.1.s‌​‌​h, I don't see anything about QtWebEngine in the sysroot directory.

I also tried to build Qt using the following command

bitbake meta-toolchain-qt5

but it is the same result; I don't have anything regarding Qt WebEngine.

How can I build Qt with QtWebEngine support?

解决方案

Looking at meta-toolchain-qt5 it inherits populate_sdk_qt5, which in turns adds packagegroup-qt5-toolchain-target to the SDK. Taking a closer look at packagegroup-qt5-toolchain-target, reveals that the packagegroup doesn't directly include qtwebengine. Thus, if nothing else in packagegroup-qt5-toolchain-target drags in qtwebengine as a dependeny, qtwebengine won't be installed.

If you add qtwebengine to RDEPENDS_${PN} in packagegroup-qt5-toolchain-target, you'll get the relevant qtwebengine packages in your SDK.
