准备

1、Python

2、Visual Studio

3、svn checkout http://google-breakpad.googlecode.com/svn/trunk/ source code

编译

1、转到google-breakpad根目录下，打开命令行，运行 src\tools\gyp\gyp.bat src\client\windows\breakpad_client.gyp --no-circular-check

如果不加 --no-circular-check 参数，将会看到以下信息：

Traceback (most recent call last):  File "D:\google_breakpad\src\tools\gyp\/gyp", line 18, in 
      
           sys.exit(gyp.main(sys.argv[1:]))  File "D:\google_breakpad\src\tools\gyp\pylib\gyp\__init__.py", line 511, in main    return gyp_main(args)  File "D:\google_breakpad\src\tools\gyp\pylib\gyp\__init__.py", line 494, in gyp_main options.circular_check)  File "D:\google_breakpad\src\tools\gyp\pylib\gyp\__init__.py", line 133, in Load    depth, generator_input_info, check, circular_check)  File "D:\google_breakpad\src\tools\gyp\pylib\gyp\input.py", line 2412, in Load    VerifyNoGYPFileCircularDependencies(targets)  File "D:\google_breakpad\src\tools\gyp\pylib\gyp\input.py", line 1536, in Veri fyNoGYPFileCircularDependencies    ' '.join(bad_files)gyp.input.CircularException: Some files not reachable, cycle in .gyp file dependency graph detected involving some or all of: src\client\windows\handler\exception_handler.gyp src\client\windows\tests\crash_generation_app\crash_generation_app.gyp src\client\windows\breakpad_client.gyp src\client\windows\sender\crash_report_sender.gyp src\client\windows\unittests\client_tests.gyp src\client\windows\crash_generation\crash_generation.gyp

2、运行之后在 src\client\windows目录下会生成一个solution，开打solution，F7生成。

注意：Debug版生成的时候一切正常，但切换到Release版本之后，生成的时候会遇到一个错误：

6>------ 已启动生成: 项目: crash_generation_server, 配置: Release Win32 ------6>生成启动时间为 2013/8/18 11:00:13。5>生成启动时间为 2013/8/18 11:00:13。6>InitializeBuildStatus:6>  正在创建“D:\google_breakpad\src\client\windows\Release\obj\crash_generation_server\crash_generation_server.unsuccessfulbuild”，因为已指定“AlwaysCreate”。5>InitializeBuildStatus:5>  正在创建“D:\google_breakpad\src\client\windows\Release\obj\common\common.unsuccessfulbuild”，因为已指定“AlwaysCreate”。6>ClCompile:6>  client_info.cc6>  minidump_generator.cc6>  crash_generation_server.cc6>crash_generation_server.cc(391): error C2220: 警告被视为错误 - 没有生成“object”文件6>crash_generation_server.cc(391): warning C4189: “error_code”: 局部变量已初始化但不引用6>crash_generation_server.cc(471): warning C4189: “error_code”: 局部变量已初始化但不引用6>crash_generation_server.cc(520): warning C4189: “error_code”: 局部变量已初始化但不引用5>ClCompile:5>  http_upload.cc5>  guid_string.cc5>  string_utils.cc2>Lib:2>  gtest.vcxproj -> D:\google_breakpad\src\client\windows\Release\lib\gtest.lib2>FinalizeBuildStatus:2>  正在删除文件“D:\google_breakpad\src\client\windows\Release\obj\gtest\gtest.unsuccessfulbuild”。2>  正在对“D:\google_breakpad\src\client\windows\Release\obj\gtest\gtest.lastbuildstate”执行 Touch 任务。2>2>生成成功。2>2>已用时间 00:00:18.076>6>生成失败。

原因是错误被视为警告的选项，在Release模式下编译的时候增加了NDEBUG选项，导致了assert被关掉了，所以error_code没有被其他地方引用到，所以编译器发出警告。

然后又被视为错误，所以导致crash_generation_server工程编译失败。

void CrashGenerationServer::HandleReadingState() {  assert(server_state_ == IPC_SERVER_STATE_READING);  DWORD bytes_count = 0;  bool success = GetOverlappedResult(pipe_,                                     &overlapped_,                                     &bytes_count,                                     FALSE) != FALSE;  DWORD error_code = success ? ERROR_SUCCESS : GetLastError();  if (success && bytes_count == sizeof(ProtocolMessage)) {    EnterStateImmediately(IPC_SERVER_STATE_READ_DONE);  } else {    // We should never get an I/O incomplete since we should not execute this    // unless the Read has finished and the overlapped event is signaled. If    // we do get INCOMPLETE, we have a bug in our code.    assert(error_code != ERROR_IO_INCOMPLETE);    EnterStateImmediately(IPC_SERVER_STATE_DISCONNECTING);  }}

最简单的解决方法是在下图的这个地方添加4189的警告。
