必备条件
首先看webengine的构建条件

首先检测
***QtGui 这个都有吧就不解释了
报错信息:QtWebEngine requires QtGui

***src/3rdparty/chromium***,这个都源码包里也有
报错信息:Submodule qtwebengine-chromium does not exist. Run ‘git submodule update --init’.

然后检测构建路径的合法性
报错信息:QtWebEngine cannot be built in a path that contains whitespace characters.

检查平台是否支持(支持的平台:Windows,Linux,macOS)
报错信息:Unknow error. Platform unspported.

构建此模块需要使用pkg-config,在编译qt的时候加上参数-pkg-config,交叉编译时会必须指定-sysroot
报错信息:pkg-config is required.

官方资料:
On Linux, Clang or GCC version 5 or later is required. Supported configurations are linux-g++ and linux-clang.
Qt WebEngine requires pkg-config to detect most of its dependencies. The following pkg-config files are required:
dbus-1
fontconfig
If Qt was configured for xcb, the following pkg-config files are also required:
libdrm
xcomposite
xcursor
xi
xrandr
xscrnsaver
xtst
Further, development packages for khr and libcap need to be installed.

确保有32位设备的环境,否则使用-no-webengine-v8-snapshot参数编译
报错信息:“V8 snapshot cannot be built. Most likely, the 32-bit host compiler does not work.”
"Please make sure you have 32-bit devel environment installed, or "
"configure webengine with ‘-no-webengine-v8-snapshot’"

需要安装gperf,bison,flex,python2
不需要交叉编译,直接安装即可
报错信息:
"Required gperf could not be found."
“Required bison could not be found.”
“Required flex could not be found.”
"A suitable version of python2 could not be found."

再次检测pkg-config,确保已经安装了pkg-config
报错信息:Host pkg-config is required

需要交叉编译glibc,
报错信息:“A suitable version of libc could not be found. See:https://sourceware.org/bugzilla/show_bug.cgi?id=14898”)

需要khr,即需要mesa库
报错信息:"khronos development headers appear to be missing (mesa/libegl1-mesa-dev)"

另外,还需要以下3个库
交叉编译dbus
交叉编译fontconfig
交叉编译nss
报错信息:"A suitable version of $$package could not be found."

最后,可能还需要xcb库

报错信息:""Could not find all necessary libraries for qpa-xcb support"
