Question

我安装了 OS X Yosemite，现在我遇到了 gcc 4.9.1 编译器的大问题。我希望有人可以帮助我。

我尝试编译我的程序并收到警告消息:

gcc: warning: couldn’t understand kern.osversion ‘14.0.0'

我在谷歌上搜索并找到 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61407我尝试应用补丁做:

sudo patch -p1 < /usr/local/bin/00-darwin-10.10.patch

在 gcc 文件夹中:/usr/local/bin/gcc我收到了消息:

can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?

我在从源代码构建东西时遇到了类似的问题，这是因为我在升级到 Yosemite 和 xcode 6.1 后忘记安装更新的命令行工具。在你的命令行中试试这个:

xcode-select --install 

这将下载并安装命令行工具，可能会解决您的问题。
