BMEM is available as compiled binaries for Windows, OS X, and Linux. Please choose the appropriate file to download. Note that the Mac binary is compiled for Darwin Kernel Version 9.8.0 and the Linux binary is for GNU/Linux Kernel Version 2.6.18-164.e15 and thus those binaries may not work for some versions of OS X and Linux.
