57 This is the source release for the FLAC project. See
61 for full documentation.
63 A brief description of the directory tree:

66 flac.pbproj/ the Mac OS X Project Builder project
67 include/ public include files for libFLAC and libFLAC++
68 man/ the man page for `flac'
69 src/ the source code and private headers
70 test/ the test scripts

74 Building in a GNU environment
75 ===============================================================================
77 FLAC uses autoconf and libtool for configuring and building.
78 Better documentation for these will be forthcoming, but in
79 general, this should work:
81 ./configure && make && make check && make install
83 The 'make check' step is optional; omit it to skip all the tests,
84 which can take several hours.
86 NOTE: Despite our best efforts it's entirely possible to have
87 problems when using older versions of autoconf, automake, or
88 libtool. If you have the latest versions and still can't get it
89 to work, see the next section on Makefile.lite.
91 There are a few FLAC-specific arguments you can give to
94 --enable-debug : Builds everything with debug symbols and some
95 extra (and more verbose) error checking.
97 --disable-asm-optimizations : Disables the compilation of the
98 assembly routines. Many routines have assembly versions for
99 speed and `configure' is pretty good about knowing what is
100 supported, but you can use this option to build only from the
103 --enable-sse : If you are building for an x86 CPU that supports
104 SSE instructions, you can enable some of the faster routines
105 if your operating system also supports SSE instructions. flac
106 can tell if the CPU supports the instructions but currently has
107 no way to test if the OS does, so if it does, you must pass
108 this argument to configure to use the SSE routines. If flac
109 crashes when built with this option you will have to go back and
110 configure without --enable-sse. Note that
111 --disable-asm-optimizations implies --disable-sse.
113 --enable-3dnow : If you are building for an AMD CPU which has 3DNOW!
114 support, you can use this flag to enable some assembly routines
115 which use 3DNOW! instructions. There have been some reports that
116 they may cause flac to crash, which is why it is not turned on
117 by default. Note that --disable-asm-optimizations overrides
123 --with-libiconv-prefix=
124 Use these if you have these packages but configure can't find them.
127 ===============================================================================
128 Building with Makefile.lite
129 ===============================================================================
131 There is a more lightweight build system for do-it-yourself-ers.
132 It is also useful if configure isn't working, which may be the
133 case since lately we've had some problems with different versions
134 of automake and libtool. The Makefile.lite system should work
135 on Gnu systems with few or no adjustments.
137 From the top level just 'make -f Makefile.lite'. You can
138 specify zero or one optional target from 'release', 'debug',
139 'test', or 'clean'. The default is 'release'. There is no
140 'install' target but everything you need will end up in the
143 If you are not on an x86 system or you don't have nasm, you
144 may have to change the DEFINES in src/libFLAC/Makefile.lite. If
145 you don't have nasm, remove -DFLAC__HAS_NASM. If your target is
146 not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN.
149 ===============================================================================
151 ===============================================================================
153 @@@@ write instructions for FLAC.dsw and *.dsp, need %NASW% set to
154 @@@@ full path to nasmw.exe
155 There is no overall make system for MSVC but the individual
156 source directories with a 'Makefile.vc' file in them allow
157 building with MSVC. Just 'nmake /f Makefile.vc'. Currently
158 the Makefile.vc for libFLAC is hardcoded to use nasm. If
159 you don't have nasm, or don't want any assembly optimizations,
160 edit the makefile, adding '/D FLAC__NO_ASM', and delete the
161 rules which compile the .nasm files.
164 ===============================================================================
166 ===============================================================================
168 If you have Fink, the Gnu flow above should work. Otherwise,
169 there is a Project Builder project in the top-level source
170 directory to build libFLAC and the command-line utilities on
171 Mac OS X. In a terminal, cd to the top-level directory (the
172 one that contains this README file) and type:
176 This will create everything and leave it in the build/ directory.
177 Don't worry about the rest of the stuff that is in build/ or
178 the stuff that was already there before building.
180 There currently is no install procedure; you will have to
181 manually copy the tools to wherever you need them.
184 ===============================================================================
185 Note to embedded developers
186 ===============================================================================
188 libFLAC has grown larger over time as more functionality has been
189 included, but much of it may be unnecessary for a particular embedded
190 implementation. Unused parts may be pruned by some simple editing of
191 configure.in and src/libFLAC/Makefile.am; the following dependency
192 graph shows which modules may be pruned without breaking things
200 seekable_stream_decoder.h
207 There is a section dedicated to embedded use in the libFLAC API
208 HTML documentation (see doc/html/api/index.html).
