Updating gcc will fix this issue: e.g., 
http://superuser.com/questions/517218/how-do-i-install-gcc-4-7-2-on-os-x-10-8. 
(You'll probably have other issues after that, though. I still can't get this 
to work on OS X.)

Got it to work with the following steps:

1) Update gcc to 4.7: 
http://superuser.com/questions/517218/how-do-i-install-gcc-4-7-2-on-os-x-10-8
2) Change "-march=native" to "-msse4.2" in makefile
3) Add "-I/usr/include/sys" to makefile "CFLAGS = " statement

It compiles if you remove the -Ofast, -Wno-unused-result and -march gcc 
options, and replace malloc.h with stdlib.h in the include statements. There 
might be a better way, though.

Thanks eaton...@gmail.com - that appears to have worked (binaries run, at least 
when not provided with arguments).

This is my modified build for mac. It worked with 8text.zip (I suggest manually 
downloading/extracting it. since the script uses wget to download and it cannot 
find it on mac.)

./distance in this mac package works with the bin generated from text8, but not 
with the freebase bin file. Just me or everyone?

A slightly better way to go about it. If you replace gcc with clang, which is 
what osx is sticking to now, then you just switch -Ofast with -O2 and 
-Who-unused-result with -Wunused-result.

I had to do the following to get the demos to work on my 10.8.2 Hackintosh:

* in the makefile:
    * replace 'gcc' with 'clang'
    * replace '-Ofast' with '-O2'
    * replace '-Who-unused-result' with '-Wunused-result'

* where needed in the *.c files, replace '#include <malloc.h>' with '#include 
<stdlib.h>'

* intall 'wget' (I used the instructions at 
http://osxdaily.com/2012/05/22/install-wget-mac-os-x/)

If the files text8 and text8-phrase do not appear after running one of the 
scripts, you can download them from http://mattmahoney.net/dc/text8.zip.

This looks like really cool technology!

Instead of getting or building wget, why not use curl.
Replace in for example demo-word.sh the wget for:
curl -o text8.gz http://mattmahoney.net/dc/text8.zip

CFLAGS = -lm -lc -pthread -O2 -msse4.2 -Wall -funroll-loops -Wunused-result

and replaced or removed all (where already present):
#include <malloc.h>
with:
#include <stdlib.h>

[GoogleCodeExporter]

after having compiled on mavericks (simple malloc.h substitution to stdlib.h 
and nothing changed in compiler parameters) word2vec works well with 
demo-word.sh and demo-phrases.sh, but not with demo-word-accuracy. I get a 
segfault at line 7, sunning only line 7 (as i already have vectors.bin used in 
demo-word.sh) i get:
./compute-accuracy vectors.bin 30000 < questions-words.txt
capital-common-countries:
Segmentation fault: 11
Any idea?

It could be related to the non-portable call to gzip when unpacking the test 
data. In fact, if you look at the demo scripts and change the line with gzip to 
the line with unzip, the demo should run.

  #gzip -d text8.gz -f
  unzip -c -d text8.gz > text8

Regarding the malloc/stdlib error, you can add block of directives to handle 
whether __APPLE__ has been defined. Something like below should work with 
distance.c, word-analogy.c, and compute-accuracy.c:

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

Best of luck!

I had issues on OS X 10.9.2, and my fix was to install gcc 4.7 using macports

1. "sudo port install gcc47" This will install gcc as gcc-mp-47 so you will 
need to change the first line in the makefile to refer to that instead of just 
"gcc".
2. Some libraries are needed from /usr/include/sys so you have to add to the 
CFLAGS statement in the makefile "-I/usr/include/sys"
3. Unfortunately, the header file time.h in /usr/include/sys is not the one you 
want because it doesn't define clock_t type. So we have to explicitly refer to 
"#include </usr/include/time.h>" in the word2vec.c file and any others that 
declare variables of clock_t type.

Hopefully this will save other time
