I'm looking at CFLAGS_FOR_BUILD and CXXFLAGS_FOR_BUILD as a way to pass
-static-libgcc and -static-libstdc++ to the linker, respectively. In the
top-level generated Makefile, I noticed that CXXFLAGS_FOR_BUILD is not included
in the list of variables in BASE_FLAGS_TO_PASS:
# Flags to pass down to all sub-makes.
BASE_FLAGS_TO_PASS = \
:
Whereas, CC_FOR_BUILD, CFLAGS_FOR_BUILD, and CXX_FOR_BUILD are included.
Is this an oversight?
And, the description of EXTRA_BUILD_FLAGS makes it sound like it should also
include the CXX variants:
# These variables must be set on the make command line for directories
# built for the build system to override those in BASE_FLAGS_TO_PASSS.
EXTRA_BUILD_FLAGS = \
CFLAGS="$(CFLAGS_FOR_BUILD)" \
LDFLAGS="$(LDFLAGS_FOR_BUILD)"
(P.S. BASE_FLAGS_TO_PASSS is misspelled.)
