Compilation error on OS X 10.8.4

[timur-almaev]

Attempt to compile the code on 10.8.4 gave me the following error: "ISO C++ does not support ‘long long’". Possibly my bad, fixed by adding "-Wno-long-long" to the list of CFLAGS.

was this an error or a warning?

(we use long long in some of the timing code, but i don't think "long long" is a standard.)

Error. As far as I know long long is only supported by C++11, which might be an issue for some systems. Below is the complete trace:

oh, sorry -- i thought this was an issue on another repo when i responded initially.

it looks like opencv is using long long in dist.h, maybe that wasn't there in a previous version of opencv. i added it to the CFLAGS as you suggested. thanks!
