This fixes object files landing in the source tree in gnu/usr.bin/dtc for GCC platforms. We cannot reliably detect if an external compiler is used here, and the default YES option does include GCC_BOOTSTRAP which implies that GCC may be used for the build. The problem manifests when not using an external compiler, and the host compiler is clang. When a fresh build is done (no OBJDIR yet) the 'make obj' treewalk is done before 'make cross-tools', so COMPILER_FEATURES at this point contains 'c++11' since the host compiler was used for COMPILER_FEATURES. Once cross-tools builds the GCC bootstrap compiler and then descends into 'make everything', COMPILER_FEATURES no longer contains 'c++11' and MK_GPL_DTC defaults to enabled. Now it builds in gnu/usr.bin/dtc without an OBJDIR preset and drops files into the source tree. The COMPILER_FEATURES check here is useful for knowing if we can *bootstrap* C++11 things. Indeed we do bootstrap dtc as a build tool so it is useful for enabling the BSD dtc for the build, but we end up needing the GPL dtc for installation anyway.

# Option file for FreeBSD /usr/src builds.
|
|
#
|
|
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
|
|
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
|
|
# with sensible (usually) defaults.
|
|
#
|
|
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
|
|
# are applicable for that Makefile (typically there are none, but sometimes there
|
|
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
|
|
# to omit from that make.
|
|
#
|
|
# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
|
|
# variable.
|
|
#
|
|
# Makefiles may also assume that this file is included by src.opts.mk should it
|
|
# need variables defined there prior to the end of the Makefile where
|
|
# bsd.{subdir,lib.bin}.mk is traditionally included.
|
|
#
|
|
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
|
|
# should be added. Old instances should be removed since they were just to
|
|
# bridge the gap between FreeBSD 4 and FreeBSD 5.
|
|
#
|
|
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
|
|
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
|
|
# completely inside bsd.*.mk files).
