CPP无法在Mac上进行健全性检查

Question

我到处搜索，无法找到如何在我的Mac上解决这个编译问题：

C预处理程序“/ lib / cpp”无法进行健全性检查

更新：我正在尝试使用./configure编译psqlodbc我得到以下内容：

configure：error：C预处理器“/ lib / cpp”无法进行健全性检查

有人会非常友善地告诉我要检查什么来开始解决可能出错的问题吗？我已经读过这个问题通常是由多个版本的编译器和XCode引起的。但是，我不知道如何开始。谢谢！

转到http://developer.apple.com/xcode，然后点击右上角的蓝色“下载”按钮。登录网站后，滚动到页面底部，您会看到“查看更多下载”链接。

在dmg文件列表中查找“命令行工具”。它应该是这样的：

获取该DMG，然后双击安装程序。它安装了可以从命令行（或Terminal.app）访问的工具（如/usr/bin/cpp）。
