问题描述

我在Ubuntu 22.10 64位虚拟机中运行Buildroot 2022.02.7，启用midori包后自动选中webkitgtk（v2.36.7），源码下载与配置无报错，但编译阶段make抛出错误终止：

[ 45%] Building CXX object Source/WebCore/CMakeFiles/WebCore.dir///WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-76.cpp.o
make[4]: *** [Source/WebCore/CMakeFiles/WebCore.dir/build.make:4281: Source/WebCore/CMakeFiles/WebCore.dir///WebCore/DerivedSources/unified-sources/UnifiedSource-3a52ce78-31.cpp.o] Error 1

make: *** [Makefile:84: _all] Error 2

回溯日志发现具体错误：

因需保留当前Buildroot配置以兼容其他项，尝试了Stack Overflow相关回答中的方案2，但编译仍失败，求解决方法。

解决方案

这个错误是WebKitGTK 2.36.7的代码兼容性问题：platformApplyNeon函数声明引用的LightingData类型未被正确引入，针对Buildroot环境可按以下步骤修复：

修改头文件补全类型引用
进入webkitgtk编译目录：
```
cd /home/dev/workspace/pios4/output/build/webkitgtk-2.36.7
```
编辑Source/WebCore/platform/graphics/filters/FELighting.h，在文件开头的#include区域添加：
```
#include "platform/graphics/filters/LightingData.h"
```
或者直接在class FELighting声明前添加前置声明：
```
struct LightingData;
```
强制重新编译webkitgtk
清理已有编译状态并重新编译：
```
make package/webkitgtk/clean
make package/webkitgtk/compile
```
禁用NEON优化（备选）
如果头文件修改无效，可通过Buildroot配置关闭NEON优化：
1. 运行make menuconfig
2. 进入Target packages -> Libraries -> Graphics -> webkitgtk
3. 取消勾选Enable NEON optimizations选项
4. 保存配置后重新执行编译

备注

若需要长期解决该问题，建议为Buildroot的webkitgtk 2.36.7包添加对应的补丁，避免每次构建都需手动修改代码。
