更改了默认 gcc 版本，现在编译问题

Question

对于安装，我必须更改我的默认 gcc 编译器版本。我使用的版本有一些编译问题，所以我通过 macports 下载了其他几个版本，其中一个最终可以用于我的安装。

我几乎可以确定我之前使用的是 gcc4.2，在我的端口中列为：llvm-gcc42。

在另外两种情况下，我现在面临 c++ 文件的编译问题。我不了解 c++，我使用编译器只是为了编译一些 - 主要是 node.js - 模块，或者现在，一个原子编辑器的包。

这是我得到的，这导致我假设 c++ 编译器的某些内容不正确：

cc1plus：错误：无法识别的命令行选项“-std=gnu++0x”

在第一种情况下，我可以通过更改默认 gcc 版本来摆脱这种情况。但我不能每次都尝试几个版本。

那么：我应该使用哪个 gcc 版本，或者还有其他可能导致这种情况的原因吗？ gcc5，最新的也一样..

---

在特定情况下：安装 termrk（原子编辑器的模块）时出现问题

gcc --version
gcc (MacPorts gcc5 5.2.0_0) 5.2.0
[...]

有两种方法可以安装 atom 包：在编辑器中使用 gui 和使用命令行工具 apm。两者都不起作用，但我收到不同的错误消息。

1.在 gui 内：

Answer 1

这是 GCC 5.2 的有效选项，所以如果它说它无法识别，则表示您没有使用 GCC 5.2。

您可能仍在使用旧的 GCC 4.2 版本进行编译。
