# Where does Berkeley DB run?

Berkeley DB requires only underlying IEEE/ANSI Std 1003.1 (POSIX) system calls and can be ported easily to new architectures by adding stub routines to connect the native system interfaces to the Berkeley DB POSIX-style system calls.

Berkeley DB will autoconfigure and run on almost any modern UNIX system, and even on most historical UNIX platforms. See Building for UNIX systems for more information.

In addition, the Berkeley DB distribution includes support for Windows/95, Windows/98, and Windows/NT, via the MSVC 4, 5 and 6 development environments. See Building for Windows systems for more information.

A port to Digital Equipment Corp.'s VMS environment is included in the Berkeley DB distribution. There are currently no known bugs in this port, but it is less well-tested than the other supported environments.
