问题描述
我正在fedora32机器上运行buildroot。
我启用了webkitgtk软件包。源的下载和配置运行没有错误
但是，在构建过程中，make会引发错误并崩溃。
我刚接触linux和GTK，将很高兴看到一些确切指出问题所在的指针。

解决方法
UnifiedSource构建错误在中继中相对常见。通常，问题是受影响的统一源文件（在本例中为UnifiedSource-3c72abbe-28.cpp）引用的某些源文件中缺少标头。
您提到WebKitGTK 2.30.2 tarball中发生了构建错误。要解决该错误，您可以尝试以下几种方法：
- 也许最简单的方法是构建更新的版本。 WebKitGTK 2.30.3刚刚在几周前发布（https://webkitgtk.org/releases/webkitgtk-2.30.3.tar.xz）
- 如果您需要专门构建2.30.2，可以尝试在禁用统一源的情况下进行构建。为此，我必须运行以下命令：
$ cmake -DPORT=GTK -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DENABLED_UNIFIED_BUILDS=OFF -DUSE_WPE_RENDERER=OFF -GNinja
似乎禁用了禁用WPE渲染所需的统一版本。
