Subject: Update Makefile for Mac OS X compilation
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=6fa6da3ee13d2b7bdbec3cd24ff8ca43233c74fb;ds=sidebyside

Update Makefile for Mac OS X compilation

This change in the Makefile restores the possibility to compile
Stockfish on Mac OS X 10.9 and 10.10 after the C++11 has been merged.

To use the default (fastest) settings, compile with:

make build ARCH=x86-64-modern

To test the clang settings, compile with

make build ARCH=x86-64-modern COMP=clang

Beware that the clang settings may provide a slightly slower (6%)
executable.

No functional change

Resolves #275
