20 FLAC (http://flac.sourceforge.net/) is an Open Source lossless audio
21 codec developed by Josh Coalson.
23 FLAC is comprised of 1) `libFLAC', a library which implements
24 reference encoders and decoders, licensed under the GNU Lesser
25 General Public License (LGPL); 2) `flac', a command-line program for
26 encoding and decoding files, licensed under the GNU General public
27 License (GPL); 3) `metaflac', a command-line program for editing
28 FLAC metadata, licensed under the GPL; 4) player plugins for XMMS
29 and Winamp, licensed under the GPL; and 5) documentation, licensed
30 under the GNU Free Documentation License.
36 This is the source release for the FLAC project. See
40 for full documentation.

50 =============================
51 Building in a GNU environment
52 =============================
54 FLAC now uses autoconf and libtool for configuring and
55 building. Better documentation for these will be
56 forthcoming, but in general, this should work:
58 ./configure ; make ; make install
60 There are a few FLAC-specific arguments you can give to
63 --enable-debug : Builds everything with debug symbols and some
64 extra (and more verbose) error checking.
66 --disable-asm-optimizations : Disables the compilation of the
67 assembly routines. Many routines have assembly versions for
68 speed and `configure' is pretty good about knowing what is
69 supported, but you can use this option to build only from the
72 --sse-os : If you are building for an x86 CPU that supports
73 SSE instructions, you can enable some of the faster routines
74 if your operating system also supports SSE instructions. flac
75 can tell if the CPU supports the instructions but currently has
76 no way to test if the OS does, so if it does, you must pass
77 this argument to configure to use the SSE routines. If flac
78 crashes when built with this option you will have to go back and
79 configure without --sse-os. Note that --disable-asm-optimizations
87 There is no overall make system for MSVC but the individual
88 source directories with a 'Makefile.vc' file in them allow
89 building with MSVC. Just 'nmake /f Makefile.vc'. Currently
90 the Makefile.vc for libFLAC is hardcoded to use nasm. If
91 you don't have nasm, or don't want any assembly optimizations,
92 edit the makefile, adding '/D FLAC__NO_ASM' and delete the
93 rules which compile the .s files.
