crashrpt3 开源项目的Vs 2022 C++20及其以上的编译

1. 首先从github 下载源代码 crashrpt3

2. 用CMake Gui 编译成vs studio 工程文件

2.1 点击 config 按钮

2.2 依次点击 Generate 按钮、Open Project 按钮.之后vs 2022 会打开编译好的sln工程文件

3.全选解决方案里面的所有项目,设置C++语言标准,我这里设置是最新C++,即启用的是C++23的标准

在这里插入图片描述根据实际需要调整32位/64位和字符串集合

设置CrashRpt工程属性

在这里插入图片描述 添加: /Zc:__cplusplus 选项,这个是解决 “__cplusplus 这个宏上，可以看到它的值展开为：199711L”

接着修改3个文件,因为C++20弃用了一些C++17的语法,导致编译失败,所以需要进行调整:

1. 修改CrashHandler.h 只有一处要修改

struct ThreadExceptionHandlers
{ThreadExceptionHandlers(){m_prevTerm = NULL;m_prevUnexp = NULL;m_prevSigFPE = NULL;m_prevSigILL = NULL;m_prevSigSEGV = NULL;}terminate_handler m_prevTerm;        // Previous terminate handler//unexpected_handler m_prevUnexp;   <-----这条语句修改为一下:
//  #if __cplusplus < 202002Lunexpected_handler m_prevUnexp;      // Previous unexpected handler (only for C++ versions < C++20)#elsestd::terminate_handler m_prevUnexp;  // Using terminate_handler as a substitute in C++20 and later
#endif
//  unexpected_handler m_prevUnexp;      // Previous unexpected handlervoid (__cdecl *m_prevSigFPE)(int);   // Previous FPE handlervoid (__cdecl *m_prevSigILL)(int);   // Previous SIGILL handlervoid (__cdecl *m_prevSigSEGV)(int);  // Previous illegal storage access handler
};

2.修改 CrashHandler.cpp 有两处要修改

int CCrashHandler::SetThreadExceptionHandlers(DWORD dwFlags)
{...//省略if(dwFlags&CR_INST_UNEXPECTED_HANDLER){// Catch unexpected() calls.// In a multithreaded environment, unexpected functions are maintained// separately for each thread. Each new thread needs to install its own// unexpected function. Thus, each thread is in charge of its own unexpected handling.// http://msdn.microsoft.com/en-us/library/h46t5b69.aspx//handlers.m_prevUnexp = set_unexpected(UnexpectedHandler);   <-----这条语句修改成以下:
/        
#if __cplusplus < 202002Lhandlers.m_prevUnexp = set_unexpected(UnexpectedHandler);
#elsehandlers.m_prevUnexp = std::set_terminate(UnexpectedHandler);
#endif
/               }
}int CCrashHandler::UnSetThreadExceptionHandlers()
{...//省略if(handlers->m_prevUnexp!=NULL){//set_unexpected(handlers->m_prevUnexp);  <-----这条语句修改成以下:
    
#if __cplusplus < 202002Lset_unexpected(handlers->m_prevUnexp);
#elseset_terminate(handlers->m_prevUnexp);
#endif
}
}

3.修改 CrashRpt.cpp 只有一处要修改

crEmulateCrash(unsigned ExceptionType) noexcept(false)
{
...//省略case CR_CPP_UNEXPECTED_CALL:{// Call unexpected// //   unexpected();  <-----这条语句修改成以下:    
// 
#if __cplusplus < 202002Lunexpected();
#elsestd::terminate();
#endif
//     }break;
}

修改完上述3个文件之后,工程就可以在C++20及其以上编译成功了.

修复一个使用中的bug:生成的crashrpt.xml和crashdump.dmp中的修改时间是UTC时间非本地时间

在 CrashSender工程里面的 ErrorReportSender.cpp

//crashdump.dmp的修改时间改成本地时间
BOOL CErrorReportSender::CreateMiniDump()
{...//省略
cleanup:
///change to local timeif (hFile != INVALID_HANDLE_VALUE) {SYSTEMTIME localTime;GetLocalTime(&localTime);  FILETIME ft;SystemTimeToFileTime(&localTime, &ft);          SetFileTime(hFile, &ft, &ft, &ft);}
/
<----------加上上述代码    // Close fileif(hFile)CloseHandle(hFile);
}
///crashrpt.xml 修改时间改成本地时间
void CErrorReportSender::AddElemToXML(CString sName, CString sValue, TiXmlNode* root)
{...//省略
cleanup://if(f)// fclose(f);//<---改为如下代码:
///if(f){fclose(f);HANDLE hFile = CreateFile(sFileName,GENERIC_WRITE,0,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);if (hFile != INVALID_HANDLE_VALUE){// Get the current local timeSYSTEMTIME localTime;GetLocalTime(&localTime);// Convert local time to FILETIMEFILETIME fileTime;SystemTimeToFileTime(&localTime, &fileTime);// Set the modification time of the fileSetFileTime(hFile, NULL, NULL, &fileTime);// Close the file handleCloseHandle(hFile);}}
//    
}
