介绍

breakpad是Google chromium项目中的一个C/C++程序崩溃日志收集工具，支持跨平台

breakpad安装

arch linux直接通过pacman安装。

从github上克隆代码

git clone https://github.com/google/breakpad.git

进入代码目录进行编译

cd breakpad
mkdir build
cd build
../configure --prefix=/usr/local
make
sudo make install

编译时会报错

../src/client/linux/crash_generation/crash_generation_client.cc:40:10: fatal error: third_party/lss/linux_syscall_support.h: 没有那个文件或目录
 #include "third_party/lss/linux_syscall_support.h"

将头文件

https://raw.githubusercontent.com/adelshokhy112/linux-syscall-support/master/lss/linux_syscall_support.h

下载到 src/third_party/lss下，新建目录lss

返回原来目录重新执行make和sudo make install

breakpad不包含cmake库，可以通过cmake调用pkg-config来找到具体安装位置和链接库

测试

CMakeLists.txt

cmake_minimum_required(VERSION 3.5)
project(test_breakpad LANGUAGES CXX)

set(CMAKE_CXX_COMPILER g++)
set(CMAKE_C_COMPILER gcc)
set(CMAKE_CXX_STANDARD 11)

if (CMAKE_BUILD_TYPE MATCHES Debug)
    message("Debug编译")
    set(CMAKE_CXX_FLAGS "-pipe -g -std=gnu++11 -Wall -D_REENTRANT -fPIC")
    set(CMAKE_C_FLAGS "-pipe -g -Wall -D_REENTRANT -fPIC")
else () #CMAKE_BUILD_TYPE MATCHES Release
    message("Release编译")
    set(CMAKE_CXX_FLAGS "-pipe -O2 -std=gnu++11 -Wall -W -D_REENTRANT -fPIC")
    set(CMAKE_C_FLAGS "-pipe -O2 -Wall -W -D_REENTRANT -fPIC")
endif ()

include(FindPkgConfig)
pkg_check_modules(BREAKPAD_CLIENT REQUIRED breakpad-client)
message(STATUS "breakpad_client目录 ${BREAKPAD_CLIENT_INCLUDE_DIRS}")
include_directories(${BREAKPAD_CLIENT_INCLUDE_DIRS})

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/output)
add_executable(test_breakpad main.cpp func.cpp func.hpp)
target_link_libraries(test_breakpad
        ${BREAKPAD_CLIENT_LIBRARIES}
        pthread)

main.cpp

#include <breakpad/client/linux/handler/exception_handler.h>
#include "func.hpp"

static bool dumpCallback(const google_breakpad::MinidumpDescriptor &descriptor,
                         void *context, bool succeeded)
{
    printf("Dump path: %s\n", descriptor.path());
    return succeeded;
}

int main(int argc, char *argv[])
{
    google_breakpad::MinidumpDescriptor descriptor("./");
    google_breakpad::ExceptionHandler eh(descriptor, nullptr, dumpCallback, nullptr, true, -1);
    crash();
    return 0;
}

func.hpp

#ifndef TEST_BREAKPAD_FUNC_HPP
#define TEST_BREAKPAD_FUNC_HPP

void crash();

#endif //TEST_BREAKPAD_FUNC_HPP

func.cpp

#include "func.hpp"

void crash()
{
    volatile int *a = (int *) (nullptr);
    *a = 1;
}

执行cmake时加上-DCMAKE_BUILD_TYPE=Debug，编译时会加上-g参数

运行编译的test_breakpad程序，会在同目录下生产一个dmp文件

执行如下两条语句：

minidump-2-core f989e168-1c4e-410b-be97d4b2-f02ba661.dmp > core
gdb test_breakpad core

最后可以看到如下输出：

Core was generated by `/home/bekl/code/test_breakpad/output/test_breakpad'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x000000000040238d in crash () at /home/bekl/code/test_breakpad/func.cpp:10
10        *a = 1;

执行cmake时加上-DCMAKE_BUILD_TYPE=Release时

可以看到输出：

Core was generated by `/home/bekl/code/test_breakpad/output/test_breakpad'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x0000000000401f50 in crash() ()

另外一种方法可以查看帮助文件：https://github.com/google/breakpad/blob/master/docs/linux_starter_guide.md#producing-symbols-for-your-application

得到的输出结果：
