C++ 促进山狮连接

我正在使用Xcode V4.4链接以在山狮上提升1.50 我使用的是GCC4.7，所以不应该涉及Xcode内容。 每次我尝试链接时，它都会告诉我：

Boost是在更新之后构建的，在更新之前可以正常工作

我尝试使用macports或自制软件构建它，但这破坏了一切…

以下是我用来在10.8上构建Boost（使用App Store中最新的Xcode）的方法，它肯定有效：

下载

tar jxvf boost_1_50_0.tar.bz2和&cd“boost_1_50_0/”

/bootstrap.sh--prefix=/opt/boost-1.50

（作为管理员用户）

sudo./b2安装

sudo ln-snf boost-1.50/opt/boost

---

你确定第五步吗？这似乎与第3步相矛盾。我的boost文件以boost_1_50_0/boost和bootstrap.sh创建/opt/boost-1.50结尾。最后一步并不重要，它只是提供了一种使用无版本路径运行的方法。每当我编译包的新版本时，我都会更新这些链接以指向最新版本。
