＃包括 <deque> 在Xcode4上

Question

I use Xcode 4.0.2 (latest update for Snow Leopard) and want to know how to include this C++ standard library and other like this.

I read some questions and answer by changing .m file to .mm files. But I don't know how to add a .mm file into my project, when I click on add a new file only see class file and other options different to .mm files.

But, It's possible to include the deque file header into am file and to add it.

Thanks.

Answer 1

添加.m文件，然后将其重命名为.mm
