Here are a couple of small possible patches for consideration (based on mdb.master3 branch): This is a trivial fix for several compilation errors (on Windows) due to unknown size of void on the mdb.master3 branch: https://github.com/kriszyp/lmdb/commit/12f1bdf9be5052728694eb5fa222688f50f84aa6.patch And then this patch makes POSIX semaphores the default on MacOS unless robust semaphores are specified (in which case it will go back to SysV semaphores): https://github.com/kriszyp/lmdb/commit/0971512f6a4aa5b05f99e481a6687d4802f70bef.patch Thanks, Kris
