Josh Coalson | 172ac00 | 2001-10-31 18:30:19 +0000 | [diff] [blame] | 59 | FLAC uses autoconf and libtool for configuring and building. |
| 60 | Better documentation for these will be forthcoming, but in |
| 61 | general, this should work: |
Josh Coalson | bb7f6b9 | 2000-12-10 04:09:52 +0000 | [diff] [blame] | 62 | |
Josh Coalson | 172ac00 | 2001-10-31 18:30:19 +0000 | [diff] [blame] | 63 | ./configure && make && make install |
Josh Coalson | bfe42f1 | 2000-12-22 22:42:25 +0000 | [diff] [blame] | 64 | |
Josh Coalson | 917df86 | 2002-07-03 07:39:05 +0000 | [diff] [blame^] | 65 | NOTE: Despite our best efforts it's entirely possible to have |
| 66 | problems when using older versions of autoconf, automake, or |
| 67 | libtool. If you have the latest versions and still can't get it |
| 68 | to work, see the next section on Makefile.lite. |

Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 70 | There are a few FLAC-specific arguments you can give to |
| 71 | `configure': |
| 72 | |
| 73 | --enable-debug : Builds everything with debug symbols and some |
| 74 | extra (and more verbose) error checking. |
| 75 | |
| 76 | --disable-asm-optimizations : Disables the compilation of the |
| 77 | assembly routines. Many routines have assembly versions for |
| 78 | speed and `configure' is pretty good about knowing what is |
| 79 | supported, but you can use this option to build only from the |
| 80 | C sources. |
| 81 | |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 82 | --enable-sse : If you are building for an x86 CPU that supports |
Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 83 | SSE instructions, you can enable some of the faster routines |
| 84 | if your operating system also supports SSE instructions. flac |
| 85 | can tell if the CPU supports the instructions but currently has |
| 86 | no way to test if the OS does, so if it does, you must pass |
| 87 | this argument to configure to use the SSE routines. If flac |
| 88 | 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] | 89 | configure without --enable-sse. Note that |
| 90 | --disable-asm-optimizations implies --disable-sse. |
Josh Coalson | 9e6efb6 | 2001-05-29 18:48:42 +0000 | [diff] [blame] | 91 | |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 92 | --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] | 93 | support, you can use this flag to enable some assembly routines |
| 94 | which use 3DNOW! instructions. There have been some reports that |
| 95 | 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] | 96 | by default. Note that --disable-asm-optimizations overrides |
Josh Coalson | e326848 | 2001-12-04 06:46:12 +0000 | [diff] [blame] | 97 | --enable-3dnow. |

Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 100 | =========================== |
| 101 | Building with Makefile.lite |
| 102 | =========================== |
| 103 | |
| 104 | There is a more lightweight build system for do-it-yourself-ers. |
| 105 | It is also useful if configure isn't working, which may be the |
| 106 | case since lately we've had some problems with different versions |
| 107 | of automake and libtool. The Makefile.lite system should work |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 108 | on Gnu systems with few or no adjustments. |
Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 109 | |
| 110 | From the top level just 'make -f Makefile.lite'. You can |
| 111 | specify zero or one optional target from 'release', 'debug', |
| 112 | 'test', or 'clean'. The default is 'release'. There is no |
| 113 | 'install' target but everything you need will end up in the |
| 114 | obj/ directory. |
| 115 | |
| 116 | If you are not on an x86 system or you don't have nasm, you |
| 117 | may have to change the DEFINES in src/libFLAC/Makefile.lite. If |
| 118 | you don't have nasm, remove -DFLAC__HAS_NASM. If your target is |
| 119 | not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. |
| 120 | |
| 121 | |

| 123 | Building with MSVC |
| 124 | ================== |
| 125 | |
| 126 | There is no overall make system for MSVC but the individual |
| 127 | source directories with a 'Makefile.vc' file in them allow |
Josh Coalson | 9e6efb6 | 2001-05-29 18:48:42 +0000 | [diff] [blame] | 128 | building with MSVC. Just 'nmake /f Makefile.vc'. Currently |
| 129 | the Makefile.vc for libFLAC is hardcoded to use nasm. If |
| 130 | you don't have nasm, or don't want any assembly optimizations, |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 131 | edit the makefile, adding '/D FLAC__NO_ASM', and delete the |
Josh Coalson | bc86950 | 2002-06-14 06:36:16 +0000 | [diff] [blame] | 132 | rules which compile the .nasm files. |
Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 133 | |
| 134 | |
| 135 | ==================== |
| 136 | Building on Mac OS X |
| 137 | ==================== |
| 138 | |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 139 | If you have Fink, the Gnu flow above should work. Otherwise, |
| 140 | there is a Project Builder project in the top-level source |
Josh Coalson | 5676eb1 | 2001-11-09 19:23:50 +0000 | [diff] [blame] | 141 | directory to build libFLAC and the command-line utilities on |
| 142 | Mac OS X. In a terminal, cd to the top-level directory (the |
| 143 | one that contains this README file) and type: |
| 144 | |
| 145 | pbxbuild -alltargets |
| 146 | |
Josh Coalson | b83801e | 2002-03-13 04:11:05 +0000 | [diff] [blame] | 147 | This will create everything and leave it in the build/ directory. |
| 148 | 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] | 149 | the stuff that was already there before building. |
| 150 | |
| 151 | There currently is no install procedure; you will have to |
| 152 | manually copy the tools to wherever you need them. |
