These instructions are valid for UNIX-like systems (these steps have been run on various Linux distributions; Darwin; Cygwin). For native Windows compilation, see ../windows/INSTALL. You must first have completed the installation steps in ../tools/INSTALL (compiling OpenFst; getting ATLAS and CLAPACK headers). The installation instructions are ./configure --shared make depend -j 8 make -j 8 Note that we added the "-j 8" to run in parallel because "make" takes a long time. 8 jobs might be too many for a laptop or small desktop machine with not many cores.
