我的 MacBook 上默认使用 GNU 4.7.1。当我在学校的服务器上运行我的程序时,我不断收到大量的段错误。我从学校服务器下载了程序的当前状态,以便可以使用 NetBeans 帮助进行调试。在让更新的 GNU 替换我的 MacBook 继续设置为默认值的古老 4.2 版本时,我遇到了很多问题。
OSX 编译器对我来说是全新的,我无法调整我的 makefile 来编译我学校服务器上的所有内容。
人们告诉我使用 gcc 或 g++ 而不是其他的,但其他人告诉我这应该没关系。据我了解,OSX 为 c/c++ 的较新版本的 GNU 使用不同的库,现在 Clang 是标准?我想坚持使用 GNU/GCC,因为那是我在我的 CS 课程中使用的。
目前看来,当我的 makefile 尝试链接“std::mt19937”时,它找不到链接它的标头。
我的问题是:如何让我的 makefile 编译以便使用 std::mt19937 和 c++11 库?

我尝试将“-std=c++0x”换成 -std=c++11 和 -std=gnu++11。我也尝试将它们都添加。我也尝试用 g++ 交换 gcc,但我似乎尝试或更改的所有内容都会导致更多错误和警告。
