#include <malloc.h>
         ^
1 error generated.
make: *** [distance] Error 1

What version of the product are you using? On what operating system?

I fixed it by replacing malloc.h with stdlib.h

malloc.h is non-standard linux-specific header.
malloc() function always exists in stdlib.h - it's guaranteed by standard.
So, stdlib.h is much better than malloc.h

Dirty solution, but it works:
In OSx Lion, Mountain Lion, Maveriks, Yosemite, the lib malloc.h is in the 
directory /usr/include/malloc
So, do:

 cd /usr/include/malloc
 sudo cp malloc.h ..

and then go to your word2vec folder and compile with make.

You have to change <malloc.h> to "malloc.h" in all of the c files. Then it will 
compiles on osx.

"malloc.h" must be removed from anywhere as a non-standatd header.
"stdlib.h" must be used instead.

Yup, replacing "malloc.h" with "stdlib.h" in three c files got it working on my 
MacBook.

because "stdlib.h" already exist in files, just delete "malloc.h".
 it works on my mac
