# Unfortunately for users of pkgsrc on stable OS versions, the latest
# version of OpenAL requires quite recent C++ standards support.
#
# We want to avoid requiring a compiler newer than what the majority
# of our packages will be built with, in order to avoid ABI issues and
# conflicts with the C++ standard library.  We also want to avoid
# requiring the user install a special compiler just to build OpenAL,
# which is a fairly stable interface.
#
# In order to best cope with this situation, older versions of OpenAL
# are selected on systems that ship older compilers by default.
#
# In order to avoid C++ standard library issues entirely, it is
# possible to set OPENAL_USE_CXX=no in mk.conf.  This will bring
# in the last version of OpenAL written in pure C.

OPENAL_USE_CXX?=	yes

# On NetBSD, avoid including compiler.mk, in case a mixture of
# GCC versions are being used to build the pkgsrc tree.
