It's not friendly for developer to compile libsairedis twice.

Hi folks,

sonic-sairedis may compile in three ways: syncd / syncd-rpc / syncd-vs.

in debian/rules:

binary: binary-syncd binary-syncd-rpc

binary-syncd:
	$(shell echo > /tmp/syncd-build)
	dh clean  --with autotools-dev
	dh build  -N syncd-rpc -N syncd-rpc-dbg -N syncd-vs -N syncd-vs-dbg --with autotools-dev
	dh binary -N syncd-rpc -N syncd-rpc-dbg -N syncd-vs -N syncd-vs-dbg --with autotools-dev

binary-syncd-rpc: | binary-syncd
	$(shell echo '--enable-rpcserver=yes' > /tmp/syncd-build)
	dh clean  --with autotools-dev
	dh build  -N syncd -N syncd-dbg -N syncd-vs -N syncd-vs-dbg --with autotools-dev
	dh binary -N syncd -N syncd-dbg -N syncd-vs -N syncd-vs-dbg --with autotools-dev

binary-syncd-vs:
	$(shell echo '--with-sai=vs' > /tmp/syncd-build)
	dh clean  --with autotools-dev
	dh build  -N syncd -N syncd-dbg -N syncd-rpc -N syncd-rpc-dbg --with autotools-dev
	dh binary -N syncd -N syncd-dbg -N syncd-rpc -N syncd-rpc-dbg --with autotools-dev

In general, we only need to compile one at a time. But now we have to compile syncd / syncd-rpc every time. It's really waste of time, especially for developer, who need to revise and debug syncd code.

Why not use configuration ENABLE_SYNCD_RPC here to distinguish which target to use?

I try a solution like sonic-buildimage/platform/vs/syncd-vs.mk using xxx_DPKG_TARGET, and it works! If I am free, I will start a PR. But I am busy now... Here's the source code:

• add sonic-buildimage/rules/syncd.mk. Maybe it's better to put syncd.mk and syncd-rpc.mk in platform/xxx and use config ENABLE_SYNCD_RPC to separate them.

$ cat rules/syncd.mk 
$(LIBSAIREDIS)_DPKG_TARGET = binary-syncd

SYNCD = syncd_1.0.0_amd64.deb
$(SYNCD)_RDEPENDS += $(LIBSAIREDIS) $(LIBSAIMETADATA)
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(SYNCD)))

SYNCD_DBG = syncd-dbg_1.0.0_amd64.deb
$(SYNCD_DBG)_DEPENDS += $(SYNCD)
$(SYNCD_DBG)_RDEPENDS += $(SYNCD)
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(SYNCD_DBG)))

• modify sonic-buildimage/rules/sairedis.mk

$ cat rules/sairedis.mk 
# sairedis package

LIBSAIREDIS = libsairedis_1.0.0_amd64.deb
$(LIBSAIREDIS)_SRC_PATH = $(SRC_PATH)/sonic-sairedis
$(LIBSAIREDIS)_DEPENDS += $(LIBSWSSCOMMON_DEV)
$(LIBSAIREDIS)_RDEPENDS += $(LIBSWSSCOMMON)
$(LIBSAIREDIS)_DEB_BUILD_OPTIONS = nocheck
SONIC_DPKG_DEBS += $(LIBSAIREDIS)

LIBSAIREDIS_DEV = libsairedis-dev_1.0.0_amd64.deb
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(LIBSAIREDIS_DEV)))

LIBSAIMETADATA = libsaimetadata_1.0.0_amd64.deb
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(LIBSAIMETADATA)))

LIBSAIMETADATA_DEV = libsaimetadata-dev_1.0.0_amd64.deb
$(LIBSAIMETADATA_DEV)_DEPENDS += $(LIBSAIMETADATA)
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(LIBSAIMETADATA_DEV)))

LIBSAIREDIS_DBG = libsairedis-dbg_1.0.0_amd64.deb
$(LIBSAIREDIS_DBG)_DEPENDS += $(LIBSAIREDIS)
$(LIBSAIREDIS_DBG)_RDEPENDS += $(LIBSAIREDIS)
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(LIBSAIREDIS_DBG)))

LIBSAIMETADATA_DBG = libsaimetadata-dbg_1.0.0_amd64.deb
$(LIBSAIMETADATA_DBG)_DEPENDS += $(LIBSAIMETADATA)
$(LIBSAIMETADATA_DBG)_RDEPENDS += $(LIBSAIMETADATA)
$(eval $(call add_derived_package,$(LIBSAIREDIS),$(LIBSAIMETADATA_DBG)))

is this issue still valid ?
