Osx sys / io.h not found

Question

I would like to compile a c program developed for linux using cc under os x. It includes the sys / io.h header. When compiling, I get an error that this file cannot be found? Is there a header file under os x in ss / io.h?

Any help would be really appreciated!

Thank!

Answer 1

Turn on <sys/uio.h>.

or why not both?

#ifdef __APPLE__
        #include <sys/uio.h>
#else
        #include <sys/io.h>
#endif

In case of Apple OS (OSX / iOS), the code will know compilation with <sys/uio.h>

Answer 2

What bibor wrote is perfect. Although my file looks something like this and works well.

#ifdef __linux

#include <io.h>

#elseif __apple

#include<uio.h>

Answer 3

$ ls /usr/include/sys/io.h
ls: /usr/include/sys/io.h: No such file or directory
