错误记录
莫名奇妙new、delete关键字相关的错误¶
- 在Source里的源文件最好加
\#include "config.h"，不然很可能报错（但其实这个只是很烦人的垃圾错误报告，但最好还是加） - 注意是源文件而不是头文件，注意模块下得有这个（比如Source/WebKit/config.h）
language设置排查¶
\#include "WebCore/ProcessIdentifier.h"
\#include <wtf/RuntimeApplicationChecks.h>
printf("[NavigatorBase] ::language, cpid=%s(%s), pid=%d, language=%s\n", Process::identifier().loggingString().utf8().data(),
WTF::processTypeDescription(WTF::processType()).characters(),
WTF::getCurrentProcessID(), defaultLanguage().utf8().data());

解决方法¶
Tools\Playwright\win\CMakeLists.txt
## WTF and bmalloc symbols live in JavaScriptCore.dll on Windows. The
## STATICALLY_LINKED_WITH_WTF / STATICALLY_LINKED_WITH_bmalloc definitions
## propagated by WebKit::WTF cause WTF_EXPORT_PRIVATE to expand to
## __declspec(dllexport) instead of __declspec(dllimport), which prevents
## lld-link from resolving the symbols via the JavaScriptCore import library.
## Override them here so the correct dllimport decoration is used.

clangd.exe --check=D:\mwk\Tools\Playwright\win\WinMain.cpp¶
在CompileFlags Add添加 "/clang:-std=c++23", # clangd drops /std:c++latest from clang-cl driver, workaround pass-through to cc1 后，解决了许多std::span/concept/byte 等cpp版本错误
