Qt Mingw 创建dump 并查找crash 出错行

前言客户现场跑的程序有可能存在长时间运行挂掉的情况而无法复现的话无法更好的查找问题原因。所以研究了一下window下程序程序调试crash的方法。该本是介绍qt mingw 的。1. 在PRO文件中加入调试信息可能导致exe增大LIBS -lDbgHelp QMAKE_CXXFLAGS_RELEASE -g QMAKE_CFLAGS_RELEASE -g QMAKE_LFLAGS_RELEASE -mthreads -Wl, #其中最后的逗号注意添加如果不添加可能编译不过 #禁止优化 QMAKE_CFLAGS_RELEASE - -O2 QMAKE_CXXFLAGS_RELEASE - -O22、dump生成类的.h文件/** * projectName * file ccrashstack * brief 记录崩溃日志 * date 2022-08-08 */ #ifndef CCRASHSTACK_H #define CCRASHSTACK_H #include windows.h #include QString class CCrashStack { private: PEXCEPTION_POINTERS m_pException; private: QString GetModuleByRetAddr(PBYTE Ret_Addr, PBYTE Module_Addr); QString GetCallStack(PEXCEPTION_POINTERS pException); QString GetVersionStr(); bool GetHardwareInaformation(QString graphics_card, QString sound_deivce); public: CCrashStack(PEXCEPTION_POINTERS pException); QString GetExceptionInfo(); }; #endif // CCRASHSTACK_H3、记录崩溃日志类的.cpp文件#include ccrashstack.h #include tlhelp32.h #include stdio.h #define _WIN32_DCOM #include comdef.h #include wbemidl.h //#includebase/constants.h #include qdebug.h CCrashStack::CCrashStack(PEXCEPTION_POINTERS pException) { m_pException pException; } QString CCrashStack::GetModuleByRetAddr(PBYTE Ret_Addr, PBYTE Module_Addr) { MODULEENTRY32 M {sizeof(M)}; HANDLE hSnapshot; wchar_t Module_Name[MAX_PATH] {0}; hSnapshot CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, 0); if ((hSnapshot !
