- before make, open Makefile, libmp3lame/Makefile and libmp3lame/i386/Makefile
|
Linux and Mac OS X or "mklink /d lame ." on Windows.
|
||||||
and replace "NASM = C:\Program Files\nasm\nasm" by "NASM = nasm" (be sure nasm is in your PATH anyway);
|
|
||||||
- For Windows x64, add --build=x86_64-w64-mingw32 to the configure line.

MS Windows notes:

|
- As an alternative to configure and a subsequent make, just use:

make -f Makefile.unix HAVE_NASM=YES NOUNIXCMD=NO UNAME=MSDOS
|
||||||
|
- Before make, open Makefile, libmp3lame/Makefile and
|
||||||
- Windows
|
libmp3lame/i386/Makefile and make sure that the path to nasm.exe is
|
||||||
|
correct (e.g. have NASM=nasm and nasm.exe on the PATH);
