- LAME 3.xx January 2001 Mark Taylor (http://www.mp3dev.org)
-
-
- =======================================================================
- Compile time options
- =======================================================================
- There are serveral targets which can be built from this
- source code:
-
- lame/lame.exe The command line encoder
-
- lame_enc.dll a Windows DLL used by many GUIs which support lame.
- (Can only be compiled by MSVC???)
-
- libmp3lame.a the *NIX style encoding library
- libmp3lame.so shared version of libmp3lame.a (not yet)
-
-
- The following compile time options can be used. For libmp3lame.a
- and lame_enc.dll, none are required. On non-unix systems,
- these options must be set in Makefile or in the IDE.
- On unix systems, they are set via ./configure.
-
-
- #define HAVE_MPGLIB compile in mpglib's mp3 *decoding* capibility
- #define HAVE_VORBIS compile in Vorbis decoding capibility
- (you need libvorbis already built)
- #define NOANALYSIS do not compile in hooks used by the
- MP3 frame analyzer.
-
-
- Options for the command line encoder:
- #define LIBSNDFILE to use Erik de Castro Lopo's libsndfile
- for input.
- #define BRHIST to allow the optional display of the VBR histogram
-
-
-
- =======================================================================
- Building the software on *NIX platforms using configure:
- =======================================================================
- Run the following commands:
-
- % ./configure
- % make
- % make install
-
- For a complete list of options, try "./configure --help"
- Some of the more usefull options:
-
- For the encoding library:
-
- --enable-mp3x Build the mp3 frame analyzer, 'mp3x'
-
- --enable-mp3rtp Build the encode-to-RTP program, 'mp3rtp'
-
-
- For the LAME front end encoder:
-
- --with-fileio=lame Use lame's internal file io routines [default]
- =sndfile Use Erik de Castro Lopo's libsndfile (no stdin possible currently)
-
- --with-sndfile-prefix=DIR Alternate location for libsndfile
- (if --with-fileio=sndfile)
-
- --enable-brhist Include the VBR bitrate histogram feature
- (default:yes if any ncurses/termcap available)"
-
-
- Other usefull configure options:
-
- --enable-debug Build a debug version
-
- --enable-expopt Enable some more optimizations flags for
- the compiler, may or may not produce
- faster code
-
- --prefix = PATH default is /usr/local
- (LAME currently installs:
- /usr/local/bin/lame
- /usr/local/lib/libmp3lame.a
- /usr/local/lib/libmp3lame.so
- /usr/local/include/lame.h
-
-
- --with-vorbis Enable Ogg Vorbis encoding/decoding support
- --with-vorbis-prefix = PATH specify where to find Vorbis libs
-
-
- Some more advanced ways to influence the build procedure
- (experienced users only, use it at your own risk):
-
- - If you want to use some custom defines for building (e.g. some out
- of the file "DEFINES") use:
-
- * bourne shell or compatible (ash, bash, zsh, ...):
- CONFIG_DEFS="-Dmy_define" ./configure
-
- * C shell or compatible (csh, tcsh, ...):
- setenv CONFIG_DEFS "-Dmy_define"
- ./configure
-
- - If you want to use some additional options for the compiler:
-
- * bourne shell or compatible (ash, bash, zsh, ...):
- CFLAGS="--my_flag" ./configure
-
- * C shell or compatible (csh, tcsh, ...):
- setenv CFLAGS "--my_flag"
- ./configure
-
- Or some combination of the above.
-
- Note:
- If configure detects the presents of "nasm" some additional speed
- improvements get compiled in (additional assembler code to detect
- and use multimedia extensions of the used processor).
-
-
- =======================================================================
- Building the software on *NIX platforms without configure:
- =======================================================================
- % make -f Makefile.unix
-
-
-
- =======================================================================
- Building the software on Windows with MSVC:
- =======================================================================
- There are MSVC project files, and a Makefile.MSVC included
- with the project. For production use, be sure to compile
- a "Release" target, with the "maximum speed" compile
- option, and #define NDEBUG.
-
- It is possible to compile the GTK frame analyzer under windows, see
- README.WINGTK
-
- Various build options can be set in configMS.h
-
-
-
- =======================================================================
- Building the software on Windows with free compilers:
- =======================================================================
- LAME can be compiled with various Windows MSDOS ports (all free)
- of GCC (DJGPP, Mingw32). See README.DJGPP.
-
- For Mingw32, you should now be able to use the Unix Makefile that
- comes with LAME. Try: "make -f Makefile.unix UNAME=MSDOS"
- You may need to remove these lines from brhist.c:
-
- #ifdef _WIN32
- COORD Pos;
- HANDLE CH;
- CONSOLE_SCREEN_BUFFER_INFO CSBI;
- #endif
-
- Mingw32 users may also try to use the unix configure script (explained
- above), it has _untested_ support for Mingw32.
-
- Cygwin users should use the unix configure script (explained above). If
- you have problems with the configure script try:
- CC=gcc ./configure
- Patches to enable the build of the lame_enc.dll with Cygwin and autoconf /
- automake / libtool are welcome!
-
- To use the Borland C compiler (now free!) see README.B32 and Makefile.B32.
- Borland can also compile the lame_enc.dll, but this is untested.
-
- Can DJGPP or Mingw32 produce lame_enc.dll?
-
- Various build options can be set in configMS.h
