| 81 | To build FLAC with support for Ogg FLAC you must have built and installed |
| 82 | libogg according to the specific instructions below. You must have |
| 83 | libogg 1.1.2 or greater, or there will be seeking problems with Ogg FLAC. |
| 84 | |
| 85 | If you are building on x86 and want the assembly optimizations, you will |
Josh Coalson | df8e732 | 2005-01-21 01:25:43 +0000 | [diff] [blame] | 86 | need to have NASM >= 0.98.30 installed according to the specific instructions |
| 87 | below. |

| 94 | libFLAC has grown larger over time as more functionality has been |
| 95 | included, but much of it may be unnecessary for a particular embedded |
| 96 | implementation. Unused parts may be pruned by some simple editing of |
Ulrich Klauer | eaae8e0 | 2013-04-30 23:10:11 +0200 | [diff] [blame] | 97 | configure.ac and src/libFLAC/Makefile.am; the following dependency |
Josh Coalson | 8c8eb71 | 2007-09-12 01:03:20 +0000 | [diff] [blame] | 98 | graph shows which modules may be pruned without breaking things |
| 99 | further down: |
| 100 | |
| 101 | metadata.h |
| 102 | stream_decoder.h |
| 103 | format.h |
| 104 | |
| 105 | stream_encoder.h |
| 106 | stream_decoder.h |
| 107 | format.h |
| 108 | |
| 109 | stream_decoder.h |
| 110 | format.h |
| 111 | |
| 112 | In other words, for pure decoding applications, both the stream encoder |
| 113 | and metadata editing interfaces can be safely removed. |
| 114 | |
| 115 | There is a section dedicated to embedded use in the libFLAC API |
| 116 | HTML documentation (see doc/html/api/index.html). |
| 117 | |
| 118 | Also, there are several places in the libFLAC code with comments marked |
| 119 | with "OPT:" where a #define can be changed to enable code that might be |
| 120 | faster on a specific platform. Experimenting with these can yield faster |
| 121 | binaries. |

Josh Coalson | 172ac00 | 2001-10-31 18:30:19 +0000 | [diff] [blame] | 128 | FLAC uses autoconf and libtool for configuring and building. |
| 129 | Better documentation for these will be forthcoming, but in |
| 130 | general, this should work: |
Josh Coalson | bb7f6b9 | 2000-12-10 04:09:52 +0000 | [diff] [blame] | 131 | |
Josh Coalson | c220cf4 | 2002-08-23 06:41:31 +0000 | [diff] [blame] | 132 | ./configure && make && make check && make install |
| 133 | |
| 134 | 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] | 135 | which can take several hours and use around 70-80 megs of disk space. |
Josh Coalson | 9d260d8 | 2003-08-28 23:47:15 +0000 | [diff] [blame] | 136 | Even though it will stop with an explicit message on any failure, it |
| 137 | does print out a lot of stuff so you might want to capture the output |
| 138 | to a file if you're having a problem. Also, don't run 'make check' |
| 139 | as root because it confuses some of the tests. |

Josh Coalson | 917df86 | 2002-07-03 07:39:05 +0000 | [diff] [blame] | 141 | NOTE: Despite our best efforts it's entirely possible to have |
| 142 | problems when using older versions of autoconf, automake, or |
| 143 | libtool. If you have the latest versions and still can't get it |
| 144 | to work, see the next section on Makefile.lite. |

Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 146 | There are a few FLAC-specific arguments you can give to |
| 147 | `configure': |
| 148 | |
| 149 | --enable-debug : Builds everything with debug symbols and some |
| 150 | extra (and more verbose) error checking. |
| 151 | |
| 152 | --disable-asm-optimizations : Disables the compilation of the |
| 153 | assembly routines. Many routines have assembly versions for |
| 154 | speed and `configure' is pretty good about knowing what is |
| 155 | supported, but you can use this option to build only from the |
Josh Coalson | 5988dd5 | 2007-09-16 20:58:12 +0000 | [diff] [blame] | 156 | C sources. May be necessary for building on OS X (Intel) |

Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 158 | --enable-sse : If you are building for an x86 CPU that supports |
Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 159 | SSE instructions, you can enable some of the faster routines |
| 160 | if your operating system also supports SSE instructions. flac |
| 161 | can tell if the CPU supports the instructions but currently has |
| 162 | no way to test if the OS does, so if it does, you must pass |
| 163 | this argument to configure to use the SSE routines. If flac |
| 164 | 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] | 165 | configure without --enable-sse. Note that |
| 166 | --disable-asm-optimizations implies --disable-sse. |
Josh Coalson | 9e6efb6 | 2001-05-29 18:48:42 +0000 | [diff] [blame] | 167 | |
Josh Coalson | 3d73072 | 2003-01-14 06:59:50 +0000 | [diff] [blame] | 168 | --enable-local-xmms-plugin : Installs the FLAC XMMS plugin in |
| 169 | $HOME/.xmms/Plugins, instead of the global XMMS plugin area |
| 170 | (usually /usr/lib/xmms/Input). |

| 186 | There is a more lightweight build system for do-it-yourself-ers. |
| 187 | It is also useful if configure isn't working, which may be the |
| 188 | case since lately we've had some problems with different versions |
| 189 | of automake and libtool. The Makefile.lite system should work |
Josh Coalson | 71fb9ff | 2002-12-03 06:29:10 +0000 | [diff] [blame] | 190 | on GNU systems with few or no adjustments. |

| 192 | From the top level just 'make -f Makefile.lite'. You can |
| 193 | specify zero or one optional target from 'release', 'debug', |
| 194 | 'test', or 'clean'. The default is 'release'. There is no |
| 195 | 'install' target but everything you need will end up in the |
| 196 | obj/ directory. |
| 197 | |
| 198 | If you are not on an x86 system or you don't have nasm, you |
| 199 | may have to change the DEFINES in src/libFLAC/Makefile.lite. If |
| 200 | you don't have nasm, remove -DFLAC__HAS_NASM. If your target is |
| 201 | not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. |
