TwoLAME is MPEG-2 audio encoder. First, compile libsndfile which is used is read sound files in various formats.
tar xzvf libsndfile-1.0.21.tar.gz cd libsndfile-1.0.21/ ./configure --prefix=/mingw --disable-shared --enable-static make make install
Then, build twolame.
tar xzvf twolame-0.3.12.tar.gz cd twolame-0.3.12/ ./configure --prefix=/mingw CPPFLAGS='-DLIBTWOLAME_STATIC' make make install
When linking a program with a static TwoLAME library, define LIBTWOLAME_STATIC with CPPFLAGS.
CPPFLAGS=' -DLIBTWOLAME_STATIC' ./configure --enable-static --enable-twolame
