I meet some trouble when I compile some C code on my mac which give me this error :
fatal error: 'endian.h' file not found
I did some google search about this problem.It seems like mac os x does not have header files like "endian.h", we have to create this file manually.
Then, I found this https://github.com/apple-oss-distributions/CarbonHeaders/blob/CarbonHeaders-18.1/Endian.h which might be the file I am looking for but not sure.
But more troubles are coming.. where should I put this file?
The file /usr/include does not exist.
These are the folders in my /usr directory:
X11 bin libexec share X11R6 lib sbin standalone
Could anyone help me to check the correctness of the endian.h file I found and tell me where to put this file in my mac please?
Xcode on OS X does not install the command-line tools by default. Depending on your Xcode and OS X version you have to
xcode-select --install from the Terminal command-line.This will also install the "/usr/include" files, including "/usr/include/machine/endian.h".
For Xcode 10 and later, see Camille G.'s answer.
