#
|
|
# This file is included by bsd.prefs.mk only if EMUL_PLATFORMS is defined
|
|
# and non-empty.
|
|
#
|
|
# User-settable variables:
|
|
#
|
|
# EMUL_TYPE.${EMUL_OPSYS}
|
|
# Specifies the "type" or "variant" of ${EMUL_OPSYS} to use, e.g.
|
|
# ${EMUL_TYPE.linux} == "suse".
|
|
#
|
|
# EMUL_PLATFORM
|
|
# Specifies the platform to emulate, and is of the form
|
|
# ${EMUL_OPSYS}-${EMUL_ARCH}, e.g. linux-i386. By default
|
|
# this is the best-matching platform listed in EMUL_PLATFORMS
|
|
# chosen based on EMUL_PREFER.
|
|
#
|
|
# EMUL_PREFER
|
|
# The list of platforms to try to emulate in order of preference.
|
|
# By default, only try to emulate the native platform. See the
|
|
# _EMUL_PREFER.* table below for additional preferences for various
|
|
# platforms.
|
|
#
|
|
# Package-settable variables:
|
|
#
|
|
# EMUL_PLATFORMS
|
|
# List of "${EMUL_OPSYS}-${EMUL_ARCH}" binary emulations supported
|
|
# by the package. This should be set prior to the inclusion of
|
|
# bsd.prefs.mk.

# Default value: undefined

# Variables defined by this file:
|
|
#
|
|
# EMUL_ARCH
|
|
# The machine architecture being emulated, e.g. i386. If the
|
|
# package isn't supported on this machine, then its value is
|
|
# "none".
|
|
#
|
|
# EMUL_OPSYS
|
|
# The operating system being emulated, e.g. linux. If the

# package isn't supported on this machine, then its value is
|
|
# "none".
|
|
#
|
|
# EMUL_IS_NATIVE
|
|
# Whether or not the operating system being emulated matches the
|
|
# native operating system. It is either defined or undefined.
