What's the Chinese equivalent of 将就? (成语) For Example: 


  正版 Windows 太贵了, 只能拿盗版Windows或Ubuntu将就一下了. 


Which can be translated to 


  Genuine Microsoft Windows is too expensive, I'll have to make do with pirated Windows or Ubuntu. 


Are there any Chengyus similar to this?
You can use 不得已而求其次 or 将陋就简. 

Both have the same meaning with 将就 or 勉强凑合.
