一、下载安装包
- 下载qbreakpad源码：
git clone https://github.com/buzzySmile/qBreakpad.git
- 下载breakpad源码
git clone https://github.com/google/breakpad
- 下载linux-syscall-support
没有这个文件，编译报错
git clone https://github.com/adelshokhy112/linux-syscall-support.git
二、编译
第一步：
cd breakpad第二步：
./configurecxx@cxx-virtual-machine:~/Demo/breakpad$ ./configure
第三步：把linux-syscall-support目录下的lss文件拷贝到breakpad/src/third_party,如下图
第四步：编译
make -j12注意：
如果make提示以下错误
./third_party/lss/linux_syscall_support.h: In member function ‘bool google_breakpad::ExceptionHandler::GenerateDump(google_breakpad::ExceptionHandler::CrashContext*)’:
./third_party/lss/linux_syscall_support.h:2146:75: error: listing the stack pointer register ‘rsp’ in a clobber list is deprecated [-Werror=deprecated]
2146 | : "rsp", "memory", "r8", "r10", "r11", "rcx");
| ^
则修改/lss/linux_syscall_support.h，如下图
重新编译
make -j12出现以下信息，则编译成功
第四步：
sudo make install查看生成文件路径
which dump_symscxx@cxx-virtual-machine:~/Demo/breakpad$ which dump_syms
/usr/local/bin/dump_syms
cxx@cxx-virtual-machine:~/Demo/breakpad$ cd /usr/local/bin
cxx@cxx-virtual-machine:/usr/local/bin$ ls
core2md dump_syms_mac minidump-2-core minidump_stackwalk pid2md
dump_syms microdump_stackwalk minidump_dump minidump_upload sym_upload
Qt中如何运用
在.pro文件中添加
INCLUDEPATH +=/usr/local/include/breakpad
LIBS +=/usr/local/lib/libbreakpad_client.a
LIBS +=/usr/local/lib/libbreakpad.a
在main.cpp中添加头文件和
#include "client/linux/handler/exception_handler.h"
#include "client/linux/handler/minidump_descriptor.h"#include "mainwindow.h"
#include <iostream>
#include <QApplication>
#include "client/linux/handler/exception_handler.h"
#include "client/linux/handler/minidump_descriptor.h"
using namespace std;
using namespace google_breakpad;
bool minidumpDB(const MinidumpDescriptor& descriptor,void* context,bool succeeded)
{
if(succeeded){
std::cout<<"Mini Dump file:"<<descriptor.path()<<std::endl;
}
return succeeded;
}
int crash(int a,int b){
return a/b;
}
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
//路径为生成.dmp文件的路径
google_breakpad::MinidumpDescriptor descriptor("/home/cxx/Demo/build-breakTest-Desktop_Qt_5_14_2_GCC_64bit-Debug");
google_breakpad::ExceptionHandler eh(descriptor,NULL,minidumpDB,NULL,true,-1);
MainWindow w;
w.show();
crash(5,0);
return a.exec();
}
在生成的可执行文件目录下，创建一个breakpad.sh文件：
breakpad.sh文件，内容如下

track_error()执行程序，即可在可执行目录下生成一个dmp文件
执行dmp解析
python3 breakpad.py ./breakTestcxx@cxx-virtual-machine:~/Demo/build-breakTest-Desktop_Qt_5_14_2_GCC_64bit-Debug$ python3 breakpad.py ./breakTest
生成sym文件:/home/cxx/Demo/build-breakTest-Desktop_Qt_5_14_2_GCC_64bit-Debug/breakTest.sym
symbols目录生成：/home/cxx/Demo/build-breakTest-Desktop_Qt_5_14_2_GCC_64bit-Debug/symbols/breakTest/EC33EEC8E77904C93D41C11D6FAE6E180
crash.log生成成功:/home/cxx/Demo/build-breakTest-Desktop_Qt_5_14_2_GCC_64bit-Debug/crash.log
生成crash.log 和error.log文件
打开crash.log，即可看到记录到的详细错误信息。
