# $FreeBSD$
#
# Allows to feature determine the compiler used
#
# MAINTAINER: portmgr@FreeBSD.org
#
# Feature: compiler
# Usage: USES=compiler or USES=compiler:ARGS
# Valid ARGS: env (default, implicit) c++11-lib c++11-lang c11 openmp features
#
# c++11-lang: The port need a compiler understanding C++11
# c++11-lib: The port need a compiler understanding C++11 and with a C++11 ready standard library
# c11: The port need a compiler understanding c11
# openmp: The port need a compiler understanding openmp
# features: The port will determine the features supported by the default compiler
#
# Variable to test after <bsd.port.pre.mk>
#
# COMPILER_TYPE: can be gcc or clang
# ALT_COMPILER_TYPE: can be gcc or clang depending on COMPILER_TYPE and only set if the base system has 2 compiler
# COMPILER_VERSION: 2 first digit of the version: 33 for clang 3.3.*, 46 for gcc 4.6.*
# ALT_COMPILER_VERSION: 2 first digit of the version: 33 for clang 3.3.*, 46 for gcc 4.6.* of the ALT_COMPILER_TYPE
#
# COMPILER_FEATURES: the list of features supported by the compiler include the standard C++ library.
# CHOSEN_COMPILER_TYPE: can be gcc or clang (type of compiler chosen by the framework)
