| 22 | |
| 23 | FLAC is comprised of 1) `libFLAC', a library which implements |

Josh Coalson | d1c9858 | 2001-01-19 22:37:36 +0000 | [diff] [blame] | 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: |
Josh Coalson | bb7f6b9 | 2000-12-10 04:09:52 +0000 | [diff] [blame] | 57 | |
Josh Coalson | d1c9858 | 2001-01-19 22:37:36 +0000 | [diff] [blame] | 58 | ./configure ; make ; make install |
Josh Coalson | bfe42f1 | 2000-12-22 22:42:25 +0000 | [diff] [blame] | 59 | |
Josh Coalson | 0403256 | 2001-07-20 23:43:15 +0000 | [diff] [blame] | 60 | If it doesn't, see the next section on Makefile.lite. |
| 61 | |
Josh Coalson | 3643db3 | 2001-07-18 00:23:06 +0000 | [diff] [blame] | 62 | There are a few FLAC-specific arguments you can give to |
| 63 | `configure': |
| 64 | |
| 65 | --enable-debug : Builds everything with debug symbols and some |
| 66 | extra (and more verbose) error checking. |
| 67 | |
| 68 | --disable-asm-optimizations : Disables the compilation of the |
| 69 | assembly routines. Many routines have assembly versions for |
| 70 | speed and `configure' is pretty good about knowing what is |
| 71 | supported, but you can use this option to build only from the |
| 72 | C sources. |
| 73 | |
| 74 | --sse-os : If you are building for an x86 CPU that supports |
| 75 | SSE instructions, you can enable some of the faster routines |
| 76 | if your operating system also supports SSE instructions. flac |
| 77 | can tell if the CPU supports the instructions but currently has |
| 78 | no way to test if the OS does, so if it does, you must pass |
| 79 | this argument to configure to use the SSE routines. If flac |
| 80 | crashes when built with this option you will have to go back and |
| 81 | configure without --sse-os. Note that --disable-asm-optimizations |
| 82 | overrides --sse-os. |

| 86 | Building with Makefile.lite |
| 87 | =========================== |
| 88 | |
| 89 | There is a more lightweight build system for do-it-yourself-ers. |
| 90 | It is also useful if configure isn't working, which may be the |
| 91 | case since lately we've had some problems with different versions |
| 92 | of automake and libtool. The Makefile.lite system should work |
| 93 | on Gnu systems with few or no minor adjustments. |
| 94 | |
| 95 | From the top level just 'make -f Makefile.lite'. You can |
| 96 | specify zero or one optional target from 'release', 'debug', |
| 97 | 'test', or 'clean'. The default is 'release'. There is no |
| 98 | 'install' target but everything you need will end up in the |
| 99 | obj/ directory. |
| 100 | |
| 101 | If you are not on an x86 system or you don't have nasm, you |
| 102 | may have to change the DEFINES in src/libFLAC/Makefile.lite. If |
| 103 | you don't have nasm, remove -DFLAC__HAS_NASM. If your target is |
| 104 | not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. |
| 105 | |

| 108 | Building with MSVC |
| 109 | ================== |
| 110 | |
| 111 | There is no overall make system for MSVC but the individual |
| 112 | source directories with a 'Makefile.vc' file in them allow |
Josh Coalson | 9e6efb6 | 2001-05-29 18:48:42 +0000 | [diff] [blame] | 113 | building with MSVC. Just 'nmake /f Makefile.vc'. Currently |
| 114 | the Makefile.vc for libFLAC is hardcoded to use nasm. If |
| 115 | you don't have nasm, or don't want any assembly optimizations, |
| 116 | edit the makefile, adding '/D FLAC__NO_ASM' and delete the |
| 117 | rules which compile the .s files. |
