Hi Michael,
Sorry to be a pain. I'm attempting to inject extra CFLAGS through the
toolchain wrappers, but I'm not sure how to do it. Here is one of my
attempts that does not work:
#
----------------------------------------------------------------------------
# Prepare
#
----------------------------------------------------------------------------
LIBTAHU_CONF_TOOL := NO
#
----------------------------------------------------------------------------
# Compile
#
----------------------------------------------------------------------------
# -D_TIME_BITS=64 requires -D_FILE_OFFSET_BITS=64
LIBTAHU_CPPFLAGS := -D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64
LIBTAHU_CFLAGS := -O2
LIBTAHU_MAKE_ENV := $(CROSS_ENV)
# Just build the dynamic library.
LIBTAHU_MAKE_OPT := \
$(CROSS_ENV_PROGS) \
lib/libtahu.so
$(STATEDIR)/libtahu.compile:
@$(call targetinfo)
@$(call world/compile, LIBTAHU)
@$(call touch)
I'm obviously missing something to pass the properly wrapped CC and CPP
variables (incorporating the extra flags) to 'make'. Could you provide a
clue how to fix it?
Are you sure it does not work? It will not be visible in the regular make
output. Run PTXdist with '-v' and then check platform-XXX/logfile.
You should find a 'wrapper: ...' line for each compiler run and the extra
flags should be visible here.
Oops, so they are! I never noticed. I understand what is going on now!
