Compiling LAME with DJGPP by S.T.L. and Christopher Wise (LAME's homepage is http://www.sulaco.org/mp3, and LAME is distributed under the LGPL. More information is in the README file) ============================================================================ Also, check out: http://www.chat.ru/~lame_djgpp/lame_djgpp.htm ============================================================================ (Note: S.T.L. doesn't know C programming (...yet) but he has learned how to compile things with DJGPP. He's not providing his E-mail address here because he wouldn't know how to answer any questions even if you asked him!) Compiling LAME with DJGPP is actually somewhat easy, though not as easy as you might expect at first glance. Here are step-by-step instructions on how to compile LAME with the latest version of DJGPP. S.T.L. runs a Pentium III 600Mhz system using Windows 98 SE. These instructions should work on any Windows 9x system and probably Windows 2000 as well, and for all true Intel Pentium III, Pentium II, Celeron, or Pentium Pro processors. The instructions can be made to work (with less optimization) on other processors including Pentium (MMX or not), 486, 386, and K6. Also this might work under DOS, but I haven't tried it. S.T.L. takes no responsibility for what you do with these instructions. Now, let's get compiling! 1) Find and install DJGPP. It's at www.delorie.com. They have a Zip Picker there that makes the process easy and painless. Make sure you also get the utilities "MAKE.EXE" and "AR.EXE". 2) Download the LAME sourcecode, preferably the latest version. Extract it to a directory using WinZip or another decompressor set to preserve the directory structure. Hopefully you already have done this, as you're reading this file! 3) Open an MSDOS window and cd into the directory with the LAME source code (the directory with all the .c and .h files, README, INSTALL, etc) 4) From the dos prompt, run: make -f Makefile.DJGPP. 5) To compile a faster version of LAME.EXE, edit "Makefile.DJGPP" and experiment with some of the other settings given for CC_OPTS. 6) Have fun! Notes on optimization: Using some of the settings for CC_OPTS won't work for non-P6-core processors. The key is the -march=i686 option. If you are running a Pentium (MMX or not), use -march=i586. For the 386 and 486, the option should now be self-explanatory! For a K6 processor, use -march=k6 . For any other type of processor, you'll just have to not use the -march option at all, which will cost you some optimization. If you'd like to create an executable that runs fast on [modern computer X], say a Pentium III, but you still want it to be able to run on any i386 or later computer, use the -mcpu=[CPU TYPE HERE], using the same cpu types as -march= accepts. The mcpu option gives less optimization, though.
