/ usr / include不能用作xcode中的搜索路径？

Question

我在/ usr / include中安装了犰狳线性代数库，所以在xcode中我将这个目录添加到搜索路径中：

但xcode警告我无法找到犰狳文件：

然后我将库文件复制到/ tmp / arma /中，并将其添加到搜索路径中：

奇迹般地一切都变好了：

我现在真的很困惑。

更新

只是为了确认犰狳确实在/ usr / include：

kaiyin@kaiyins-mbp 07:30:09 | ~ =>
cd /usr/include/
kaiyin@kaiyins-mbp 07:30:20 | /usr/include =>
realpath armadillo
/usr/include/armadillo
kaiyin@kaiyins-mbp 07:30:25 | /usr/include =>
ll armadillo
-rw-r--r--  1 root  wheel    20K Jun  1 04:44 armadillo
kaiyin@kaiyins-mbp 07:31:24 | /usr/include =>
file armadillo
armadillo: ASCII C++ program text
kaiyin@kaiyins-mbp 07:31:29 | /usr/include =>
head armadillo

#ifndef ARMA_INCLUDES
#define ARMA_INCLUDES
kaiyin@kaiyins-mbp 07:31:32 | /usr/include =>
diff /tmp/arma/armadillo armadillo
kaiyin@kaiyins-mbp 07:32:11 | /usr/include =>

所以它坐在那里和/ tmp / arma /

中的那个相同

Answer 1

是的，它适用于MAC。实际上它在任何类似Unix的系统中都能正常工作。
