我正在尝试使用10.12.6 Sierra在Mac上构建ITK。要安装，我按照以下步骤操作：
cmake ../ITK，指向ITK源目录，这很好。make
在最后一步中，我得到以下错误，指向Core Foundation Framework中的头文件：

我不熟悉此代码，不知道错误是指什么。我能解决这个问题吗？
提前致谢。
答案 0 :(得分：1)
我通过设置
使用clang编译器重试它$ export CC=/usr/bin/clang
$ export CXX=/usr/bin/clang++
在我运行cmake ../ITK和make之前，而不是默认使用的gcc-5 / g ++ - 5编译器，它运行了！
