# This Makefile fragment (since dpkg 1.16.1) defines the following host # variables: # # ASFLAGS: flags for the host assembler (since 1.21.0). # CFLAGS: flags for the host C compiler. # CPPFLAGS: flags for the host C preprocessor. # CXXFLAGS: flags for the host C++ compiler. # OBJCFLAGS: flags for the host Objective C compiler. # OBJCXXFLAGS: flags for the host Objective C++ compiler. # DFLAGS: flags for the host D compiler. # FFLAGS: flags for the host Fortran 77 compiler. # FCFLAGS: flags for the host Fortran 9x compiler. # LDFLAGS: flags for the host linker. # # And the following variables for the build tools (since dpkg 1.22.1): # # ASFLAGS_FOR_BUILD: flags for the build assembler. # CFLAGS_FOR_BUILD: flags for the build C compiler. # CPPFLAGS_FOR_BUILD: flags for the build C preprocessor. # CXXFLAGS_FOR_BUILD: flags for the build C++ compiler. # OBJCFLAGS_FOR_BUILD: flags for the build Objective C compiler. # OBJCXXFLAGS_FOR_BUILD: flags for the build Objective C++ compiler. # DFLAGS_FOR_BUILD: flags for the build D compiler. # FFLAGS_FOR_BUILD: flags for the build Fortran 77 compiler. # FCFLAGS_FOR_BUILD: flags for the build Fortran 9x compiler. # LDFLAGS_FOR_BUILD: flags for the build linker. # # You can also export them in the environment by setting # DPKG_EXPORT_BUILDFLAGS to a non-empty value. # # This list is kept in sync with the default set of flags returned # by dpkg-buildflags. dpkg_lazy_eval ?= $$(or $$(value DPKG_CACHE_$(1)),$$(eval DPKG_CACHE_$(1) := $$(shell $(2)))$$(value DPKG_CACHE_$(1))) DPKG_BUILDFLAGS_LIST = \ ASFLAGS \ ASFLAGS_FOR_BUILD \ CFLAGS \ CFLAGS_FOR_BUILD \ CPPFLAGS \ CPPFLAGS_FOR_BUILD \ CXXFLAGS \ CXXFLAGS_FOR_BUILD \ OBJCFLAGS \ OBJCFLAGS_FOR_BUILD \ OBJCXXFLAGS \ OBJCXXFLAGS_FOR_BUILD \ DFLAGS \ DFLAGS_FOR_BUILD \ FFLAGS \ FFLAGS_FOR_BUILD \ FCFLAGS \ FCFLAGS_FOR_BUILD \ LDFLAGS \ LDFLAGS_FOR_BUILD \ # EOL define dpkg_buildflags_export_envvar ifdef $(1) DPKG_BUILDFLAGS_EXPORT_ENVVAR += $(1)="$$(value $(1))" endif endef $(eval $(call dpkg_buildflags_export_envvar,DEB_BUILD_OPTIONS)) $(eval $(call dpkg_buildflags_export_envvar,DEB_BUILD_MAINT_OPTIONS)) $(eval $(call dpkg_buildflags_export_envvar,DEB_BUILD_PATH)) $(foreach flag,$(DPKG_BUILDFLAGS_LIST),\ $(foreach operation,SET STRIP APPEND PREPEND,\ $(eval $(call dpkg_buildflags_export_envvar,DEB_$(flag)_MAINT_$(operation))))) dpkg_buildflags_setvar = $(1) = $(call dpkg_lazy_eval,$(1),$(DPKG_BUILDFLAGS_EXPORT_ENVVAR) dpkg-buildflags --get $(1)) $(foreach flag,$(DPKG_BUILDFLAGS_LIST),\ $(eval $(call dpkg_buildflags_setvar,$(flag)))) ifdef DPKG_EXPORT_BUILDFLAGS export $(DPKG_BUILDFLAGS_LIST) endif
