If you need it, it's an excellent reason to integrate it. Moreover we can guess that you're not alone to have this need. > The dpdk library must still be compiled using gcc.

Anyway, let me know if it's worthwhile to submit a patch. I think that it should be documented. What about a file doc/build-app.rst ? You could start documenting how it is different for C++. > +ifeq ($(CC), $(CROSS)g++) > +TOOLCHAIN_CFLAGS += -D__STDC_LIMIT_MACROS > +WERROR_FLAGS := -W -Wall -Werror > +WERROR_FLAGS += -Wmissing-declarations -Wpointer-arith > +WERROR_FLAGS += -Wcast-align -Wcast-qual > +else > WERROR_FLAGS := -W -Wall -Werror -Wstrict-prototypes -Wmissing-prototypes > WERROR_FLAGS += -Wmissing-declarations -Wold-style-definition > -Wpointer-arith > WERROR_FLAGS += -Wcast-align -Wnested-externs -Wcast-qual > +endif > WERROR_FLAGS += -Wformat-nonliteral -Wformat-security Could you factorize the common flags, please ?
