./configure ; make ; make install
To disable all assembly optimizations, pass the
--disable-asm-optimizations flag to configure.
There are a few FLAC-specific arguments you can give to
`configure':
--enable-debug : Builds everything with debug symbols and some
extra (and more verbose) error checking.
--disable-asm-optimizations : Disables the compilation of the
assembly routines. Many routines have assembly versions for
speed and `configure' is pretty good about knowing what is
supported, but you can use this option to build only from the
C sources.
--sse-os : If you are building for an x86 CPU that supports
SSE instructions, you can enable some of the faster routines
if your operating system also supports SSE instructions. flac
can tell if the CPU supports the instructions but currently has
no way to test if the OS does, so if it does, you must pass
this argument to configure to use the SSE routines. If flac
crashes when built with this option you will have to go back and
configure without --sse-os. Note that --disable-asm-optimizations
overrides --sse-os.
