| 20 | FLAC (http://flac.sourceforge.net/) is an Open Source lossless audio |
| 21 | codec developed by Josh Coalson. |
| 22 | |
Josh Coalson | bc86950 | 2002-06-14 06:36:16 +0000 | [diff] [blame] | 23 | FLAC is comprised of |
| 24 | * `libFLAC', a library which implements reference encoders and |
Josh Coalson | 0c3524c | 2002-08-22 04:21:54 +0000 | [diff] [blame] | 25 | decoders, and a metadata interface |
Josh Coalson | bc86950 | 2002-06-14 06:36:16 +0000 | [diff] [blame] | 26 | * `libFLAC++', a C++ object wrapper library around libFLAC |
Josh Coalson | 0c3524c | 2002-08-22 04:21:54 +0000 | [diff] [blame] | 27 | * `libOggFLAC' and `libOggFLAC++', which provide encoders and |
| 28 | decoders for FLAC streams in an Ogg container |
| 29 | * `flac', a command-line program for encoding and decoding files |
| 30 | * `metaflac', a command-line program for editing FLAC metadata |

Josh Coalson | 172ac00 | 2001-10-31 18:30:19 +0000 | [diff] [blame] | 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: |
Josh Coalson | bb7f6b9 | 2000-12-10 04:09:52 +0000 | [diff] [blame] | 80 | |
Josh Coalson | c220cf4 | 2002-08-23 06:41:31 +0000 | [diff] [blame] | 81 | ./configure && make && make check && make install |
| 82 | |
| 83 | The 'make check' step is optional; omit it to skip all the tests, |
Josh Coalson | ccea6aa | 2002-12-17 08:14:42 +0000 | [diff] [blame] | 84 | which can take several hours and use around 70-80 megs of disk space. |
Josh Coalson | bfe42f1 | 2000-12-22 22:42:25 +0000 | [diff] [blame] | 85 | |
Josh Coalson | 917df86 | 2002-07-03 07:39:05 +0000 | [diff] [blame] | 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. |
Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 90 | |
Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 91 | There are a few FLAC-specific arguments you can give to |
| 92 | `configure': |
| 93 | |
| 94 | --enable-debug : Builds everything with debug symbols and some |
| 95 | extra (and more verbose) error checking. |
| 96 | |
| 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 |
| 101 | C sources. |
| 102 | |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 103 | --enable-sse : If you are building for an x86 CPU that supports |
Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 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 |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 110 | configure without --enable-sse. Note that |
| 111 | --disable-asm-optimizations implies --disable-sse. |
Josh Coalson | 9e6efb6 | 2001-05-29 18:48:42 +0000 | [diff] [blame] | 112 | |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 113 | --enable-3dnow : If you are building for an AMD CPU which has 3DNOW! |
Josh Coalson | c69f878 | 2001-11-13 23:08:22 +0000 | [diff] [blame] | 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 |
Josh Coalson | 7140a1c | 2001-11-13 23:11:51 +0000 | [diff] [blame] | 117 | by default. Note that --disable-asm-optimizations overrides |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 118 | --enable-3dnow. |
Josh Coalson | c69f878 | 2001-11-13 23:08:22 +0000 | [diff] [blame] | 119 | |
Josh Coalson | 822eef6 | 2002-09-12 06:40:44 +0000 | [diff] [blame] | 120 | --with-ogg= |
| 121 | --with-id3lib= |
| 122 | --with-xmms-prefix= |
| 123 | --with-libiconv-prefix= |
| 124 | Use these if you have these packages but configure can't find them. |
| 125 | |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 126 | If you want to build completely from scratch (i.e. starting with just |
| 127 | configure.in and Makefile.am) you should be able to just run 'autogen.sh' |
| 128 | but make sure and read the comments in that file first. |

Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 132 | Building with Makefile.lite |
Josh Coalson | 310b9ec | 2002-07-31 06:39:21 +0000 | [diff] [blame] | 133 | =============================================================================== |
Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 134 | |
| 135 | There is a more lightweight build system for do-it-yourself-ers. |
| 136 | It is also useful if configure isn't working, which may be the |
| 137 | case since lately we've had some problems with different versions |
| 138 | of automake and libtool. The Makefile.lite system should work |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 139 | on GNU systems with few or no adjustments. |
Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 140 | |
| 141 | From the top level just 'make -f Makefile.lite'. You can |
| 142 | specify zero or one optional target from 'release', 'debug', |
| 143 | 'test', or 'clean'. The default is 'release'. There is no |
| 144 | 'install' target but everything you need will end up in the |
| 145 | obj/ directory. |
| 146 | |
| 147 | If you are not on an x86 system or you don't have nasm, you |
| 148 | may have to change the DEFINES in src/libFLAC/Makefile.lite. If |
| 149 | you don't have nasm, remove -DFLAC__HAS_NASM. If your target is |
| 150 | not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. |
| 151 | |

Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 157 | There are two ways to build with MSVC: |
| 158 | |
| 159 | 1. Project Files |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 160 | ---------------- |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 161 | Prerequisite: you must have the Ogg libraries installed as described |
| 162 | later. |
| 163 | |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 164 | Prerequisite: you must have nasm installed, and have the environment |
| 165 | variable FLAC_NASM set to the full path to nasmw.exe, e.g |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 166 | |
| 167 | C:\nasm\nasmw.exe |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 168 | |
| 169 | To build everything, run Developer Studio, do File|Open Workspace, |
| 170 | and open FLAC.dsw. Switch to the 'Files' tab, select 'all files' |
| 171 | from the tree, do right-mouse-button and 'Set as active project'. |
Josh Coalson | 7d518fd | 2002-10-18 05:57:06 +0000 | [diff] [blame] | 172 | The default build mode will probably be Debug; to change to release |
| 173 | do Build|Set Active Configuration and select 'all - Win32 Release'. |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 174 | Then do Project|Build. This will build all libraries both statically |
| 175 | (e.g. obj\debug\lib\libFLAC_static.lib) and as DLLs (e.g. |
| 176 | obj\debug\bin\libFLAC.dll), and it will build all binaries, statically |
| 177 | linked (e.g. obj\debug\bin\flac.exe). |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 178 | |
| 179 | 2. nmake |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 180 | -------- |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 181 | Prerequisite: you must have the Ogg libraries installed as described |
| 182 | later. |
| 183 | |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 184 | Prerequisite: you must have nasm installed and nasmw.exe must be in |
| 185 | your path. |
| 186 | |
| 187 | To build everything, open a Command window, cd to the top-level |
| 188 | directory (where this README is) and do |
| 189 | |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 190 | nmake /f Makefile.vc |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 191 | |
| 192 | This will recur into all the source directories in the right order |
| 193 | and build everything. The libraries will be build only as static |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 194 | libs. You need only to install the binaries. To clean up everything |
| 195 | you can do |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 196 | |
Josh Coalson | a11d5de | 2002-10-18 06:09:38 +0000 | [diff] [blame] | 197 | nmake /f Makefile.vc clean |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 198 | |
| 199 | from the top level directory, or any directory which has a |
| 200 | Makefile.vc |
| 201 | |
| 202 | Everything will end up in the 'obj' directory. DLLs and .exe files |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 203 | are all that are needed and can be copied to an installation area and |
Josh Coalson | 3a17d3c | 2002-10-18 05:49:44 +0000 | [diff] [blame] | 204 | added to the PATH. The plugins have to be copied to their appropriate |
Josh Coalson | 7d518fd | 2002-10-18 05:57:06 +0000 | [diff] [blame] | 205 | place in the player area. For Winamp2 this is <winamp2-dir>\Plugins |
| 206 | and for Winamp3 this is <winamp3-dir>\Wacs. |
Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 207 | |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 208 | By default the code is configured with Ogg support. Before building FLAC |
| 209 | you will need to get the Ogg source distribution |
| 210 | (see http://xiph.org/ogg/vorbis/download/), build ogg_static.lib (load and |
| 211 | build win32\ogg_static.dsp), copy ogg_static.lib into FLAC's |
| 212 | 'obj\release\lib' directory, and copy the entire include\ogg tree into |
| 213 | FLAC's 'include' directory (so that there is an 'ogg' directory in FLAC's |
| 214 | 'include' directory with the files ogg.h, os_types.h and config_types.h). |
| 215 | |

Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 220 | |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 221 | If you have Fink, the GNU flow above should work. Otherwise, |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 222 | there is a Project Builder project in the top-level source |
Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 223 | directory to build libFLAC and the command-line utilities on |
| 224 | Mac OS X. In a terminal, cd to the top-level directory (the |
| 225 | one that contains this README file) and type: |
| 226 | |
| 227 | pbxbuild -alltargets |
| 228 | |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 229 | This will create everything and leave it in the build/ directory. |
| 230 | Don't worry about the rest of the stuff that is in build/ or |
Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 231 | the stuff that was already there before building. |
| 232 | |
| 233 | There currently is no install procedure; you will have to |
| 234 | manually copy the tools to wherever you need them. |

| 240 | |
| 241 | libFLAC has grown larger over time as more functionality has been |
| 242 | included, but much of it may be unnecessary for a particular embedded |
| 243 | implementation. Unused parts may be pruned by some simple editing of |
| 244 | configure.in and src/libFLAC/Makefile.am; the following dependency |
| 245 | graph shows which modules may be pruned without breaking things |
| 246 | further down: |
| 247 | |
| 248 | file_encoder.h |
| 249 | stream_encoder.h |
| 250 | format.h |
| 251 | |
