如何构建Google BreakPad

我完全迷恋如何建立谷歌的breakpad。有一个SLN文件,但它取决于似乎没有关联SLN的库。好像用的是一种叫Gyp的东西,我还没弄明白怎么去上班。我试过

 python gyp  ..\breakpad\src\client\windows\breakpad_client.gyp

这就产生了以下错误

Traceback (most recent call last):
File "gyp", line 18, in <module>
sys.exit(gyp.main(sys.argv[1:]))
 File "pylib\gyp\__init__.py", line 445, in main

..\breakpad\src\client\windows\unittests\client_tests.gyp   
..\breakpad\src\client\windows\crash_generation\crash_generation.gyp

我完全搞不懂。我也找不到任何文件。任何帮助都将不胜感激。
