不完整的WEBKITGTK构建

Question

我正在fedora32机器上运行buildroot。

我介绍了这个网络小猫的包裹。下载和配置源运行时没有出现错误。

但是，在构建过程中，make抛出一个错误并崩溃。

我对linux和GTK非常陌生，我会很高兴地欣赏一些关于到底出了什么问题的建议。

下面是构建失败之前终端上输出的摘录。

Answer 1

UnifiedSource构建错误在主干中比较常见。通常，受影响的统一源文件引用的一些源文件中缺少标题，在本例中是UnifiedSource-3c72abbe-28.cpp。

您提到在WebKitGTK 2.30.2 tarball中发生了构建错误。要修复错误，您可以尝试以下几种方法：

1. 也许最简单的方法就是构建一个更新的版本。(https://webkitgtk.org/releases/webkitgtk-2.30.3.tar.xz)
2. If 2.30.3是几周前发布的--您需要构建2.30.2 --具体来说，您可以尝试使用禁用的统一源代码构建。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

似乎禁用禁用WPE呈现所需的统一构建。
