To build everything, run Visual Studio, do File|Open and open FLAC.sln.
From the dropdown in the toolbar, select "Release" instead of "Debug",
then hit F7 to build.
-Either way, this will build all libraries both statically (e.g.
-obj\release\lib\libFLAC_static.lib) and as DLLs (e.g.

Building on Mac OS X
===============================================================================
-If you have Fink, the GNU flow above should work. Otherwise,
-there is a Project Builder project in the top-level source
-directory to build libFLAC and the command-line utilities on
-Mac OS X. In a terminal, cd to the top-level directory (the
-one that contains this README file) and type:
-
- pbxbuild -alltargets
-
-This will create everything and leave it in the build/ directory.
-Don't worry about the rest of the stuff that is in build/ or
-the stuff that was already there before building.
-
-The Project Builder project requires that you have libiconv and
-libogg in /sw, ala fink. If you don't, you'll need to install
-them somewhere and change the path to them in the Library Paths
-section of several targets.
-
-It also assumes the CPU supports Altivec instructions. If it does
-not, you will also have to add -DFLAC__NO_ASM to the CFLAGS in the
-libFLAC target.
-
-There currently is no install procedure; you will have to
-manually copy the tools to wherever you need them.
