Optimal build on OS X

Using OS X, you can install Xcode (free) and then its "command line tools" and after that a normal build should work fine. However, using native gcc (which is really clang) results in suboptimal performance and some formats are disabled due to ancient OpenSSL.

Here's how to make the best possible of your hardware. There are alternatives that probably work fine but these instructions are for "Homebrew":

1. Install Homebrew: http://mxcl.github.io/homebrew/
2. Install Homebrew's gcc and openssl:

brew install gcc openssl

3. Make sure /usr/local/bin precedes /usr/bin in your $PATH
4. Provide the path to GCC and the OpenSSL libraries to the configure script:

./configure CC="gcc-6" CPPFLAGS="-I/usr/local/opt/openssl/include" LDFLAGS="-L/usr/local/opt/openssl/lib"

5. Clean old files and make:

make -s clean && make -sj4

After the above, you should be able to get an optimal build with AVX and/or whatever extra features your CPU has got.

If you get weird problems including things like "error: unknown type name 'dispatch_block_t'" on 10.10 Yosemite, you might need to apply a patch for the system headers (at your own risk, as always, but backups are created). From John's "src" directory:

sudo patch -b -N -p0 < unused/Yosemite.patch

The patch is not needed for 10.11 "El Capitan".

NOTE: The above command will create backup files. If you ever want to restore everything as it were originally:

cd /usr/include/dispatch
sudo mv -vi object.h.orig object.h
sudo mv -vi queue.h.orig queue.h
cd -
