Solution to "Missing malloc.h" problem in MacOSX

[james.lin]

Hi Ruud,

Problem: I have compiled the examples source in MacOX 10.5.5 with Intel C plus plus compiler 10.1, and met "Missing headfile malloc.h" problem in Chapter6.

Reason: someone said, Apple put malloc.h in different place . Actually it was expecting it to be in the /usr/include directory, when it was actually in the /usr/include/malloc directory.

Possible Solution: edit the source code, 1)remove or comment #include <malloc.h> or 2) change it to #include <malloc/malloc.h>

hope this help.

Hi Xinhua,

Thank you very much for trying out these examples on Mac OS X and for the feedback!

This is very good to know and I hope it benefits others.

It is unfortunate this file is not in /usr/include. I'm not sure leaving out the
#include <malloc.h> line is going to work on other systems though and am
concerned it might break things.

Maybe this can be solved by using an option on the compiler to also let it search
in non-default include directories.

Kind regards, Ruud

Hi Ruud,

Thanks for your reply. I understand your concern about portability. So how about adding a Marco, such as

Code: Select all

#ifndef __APPLE__
#include <malloc.h>
#endif

or one more readable:

Code: Select all

#ifdef __APPLE__
#   include <malloc/malloc.h>
#else
#   include <malloc.h>   
#endif

into the source file?

Per the C99 standard, malloc() is declared in stdlib.h.
