55 =============================
56 Building in a GNU environment
57 =============================
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:
63 ./configure && make && make install
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.
70 There are a few FLAC-specific arguments you can give to
73 --enable-debug : Builds everything with debug symbols and some
74 extra (and more verbose) error checking.
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
82 --enable-sse : If you are building for an x86 CPU that supports
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
89 configure without --enable-sse. Note that
90 --disable-asm-optimizations implies --disable-sse.
92 --enable-3dnow : If you are building for an AMD CPU which has 3DNOW!
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
96 by default. Note that --disable-asm-optimizations overrides
100 ===========================
101 Building with Makefile.lite
102 ===========================
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
108 on Gnu systems with few or no adjustments.
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
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.
126 There is no overall make system for MSVC but the individual
127 source directories with a 'Makefile.vc' file in them allow
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,
131 edit the makefile, adding '/D FLAC__NO_ASM', and delete the
132 rules which compile the .nasm files.
139 If you have Fink, the Gnu flow above should work. Otherwise,
140 there is a Project Builder project in the top-level source
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:
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
149 the stuff that was already there before building.
151 There currently is no install procedure; you will have to
152 manually copy the tools to wherever you need them.
