@ -57,8 +57,27 @@ forthcoming, but in general, this should work:
|
||||
|
||||
./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.
