OS-X支持std :: tr1 [英] OS-X support for std::tr1
问题描述
目前对于tr1或Mac上的新C ++ 0x的支持
What is the current support for tr1 or the new C++0x on the Mac
我知道XCode附带的gcc总是有几个版本可以从gcc.gnu.org得到,所以我只是想知道现代支持的状态是什么。
I know that the gcc supplied with XCode is always a couple of versions behind that available from gcc.gnu.org so I was just wondering what the state of play for modern support was.
例如,我需要下载boost使用shared_ptr或我可以从std :: tr1吗?
For example do I need to download boost to use shared_ptr or can I get it from std::tr1?
推荐答案
OS X 10.6附带g ++ 4.2.1以及g ++ 4.0,但它应该是直接安装自己的构建,如果你选择。 GNU工具是真棒的。这是建立在我的机器上,一个雪豹Mac与g ++ 4.2.1:
OS X 10.6 ships with g++ 4.2.1 as well as g++ 4.0, but it should be straightforward to install your own build if you choose to. GNU tools are awesome for that. This builds on my machine, a Snow Leopard Mac with g++ 4.2.1:
#include <tr1/memory>
int main(int argc, char* argv[])
{
std::tr1::shared_ptr<int> p;
return 0;
}
