c++ 在Mac OS X Yosemite 10.10.1上包含搜索路径

我想更改包含搜索路径.特别是,我首先需要/usr/local / include.

但由于重复,它不会改变.我该怎么改变它？

我想有默认设置,因为我没有指定的路径出现.像/usr/include / c /4.2.1,/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/6.0/include

那么……这条路径/usr/include / c /4.2.1来自哪里？

我得到了一些提示吗？

等等,导出CFLAGS =“ – I / path / to / preferred / HDF5 / hdf5.h”不起作用……

正如所料,重复目录被忽略,订单不会改变.

但是,我找到了clang的-include选项,它可以指定一个文件！
