Unfortunately both major and minor were used causing version 20.1 to be incompatible with 20.0. This patch fixes the issue by switching from 2-part to 3-part ABI version numbers so that we can keep 20.0 as soname and using the final digits to identify the 20.x releases which are ABI compatible. This requires changes to both make and meson builds to handle the three-digit version and shrink it to 2-digit for soname. Fixes: cba806e07d6f ("build: change ABI versioning to global") Signed-off-by: Bruce Richardson Signed-off-by: Thomas Monjalon --- V2: * adjusted the meson version to work correctly with both 2-part and 3-part ABI versions, so it will work correctly even with no changes for a 21.x ABI version number * adjusted the versions of the experimental libs so that they are consistent between meson and make, and also consistent with v19.11 --- ABI_VERSION | 2 +- config/meson.build | 16 +++++++++++++--- drivers/meson.build | 4 ++-- lib/meson.build | 4 ++-- mk/rte.lib.mk | 11 +++++++---- 5 files changed, 25 insertions(+), 12 deletions(-) diff --git a/ABI_VERSION b/ABI_VERSION index 2e73f8d2a..fcc01369a 100644 --- a/ABI_VERSION +++ b/ABI_VERSION @@ -1 +1 @@ -20.1 +20.0.1 diff --git a/config/meson.build b/config/meson.build index 364a8d739..01911ecf9 100644 --- a/config/meson.build +++ b/config/meson.build @@ -20,9 +20,19 @@ pver = meson.project_version().split('.') major_version = '@0@.@1@'.format(pver.get(0), pver.get(1)) abi_version = run_command(find_program('cat', 'more'), abi_version_file).stdout().strip() -# experimental libraries are versioned as 0.majorminor versions, e.g. 0.201 -ever = abi_version.split('.') -experimental_abi_version = '0.@0@@1@'.format(ever.get(0), ever.get(1)) + +# Regular libraries have the abi_version as the filename extension +# and have the soname be all but the final part of the abi_version. +# Experimental libraries have soname with '0.major' +# and the filename suffix as 0.majorminor versions, +# e.g. v20.1 => librte_stable.so.20.1, librte_experimental.so.0.201 +# sonames => librte_stable.so.20, librte_experimental.so.0.20 +# e.g. v20.0.1 => librte_stable.so.20.0.1, librte_experimental.so.0.2001 +# sonames => librte_stable.so.20.0, librte_experimental.so.0.200 +abi_va = abi_version.split('.') +stable_so_version = abi_va.length() == 2 ? abi_va[0] : abi_va[0] + '.' + abi_va[1] +experimental_abi_version = '0.' + ''.join(abi_va) +experimental_so_version = '0.' + ''.join(stable_so_version.split('.')) # extract all version information into the build configuration dpdk_conf.set('RTE_VER_YEAR', pver.get(0).to_int()) diff --git a/drivers/meson.build b/drivers/meson.build index 72eec4608..4b17662b7 100644 --- a/drivers/meson.build +++ b/drivers/meson.build @@ -132,10 +132,10 @@ foreach class:dpdk_driver_classes if is_experimental != 0 lib_version = experimental_abi_version - so_version = experimental_abi_version + so_version = experimental_so_version else lib_version = abi_version - so_version = abi_version + so_version = stable_so_version endif # now build the static driver diff --git a/lib/meson.build b/lib/meson.build index 6ceb5e756..0af3efab2 100644 --- a/lib/meson.build +++ b/lib/meson.build @@ -113,10 +113,10 @@ foreach l:libraries if is_experimental != 0 lib_version = experimental_abi_version - so_version = experimental_abi_version + so_version = experimental_so_version else lib_version = abi_version - so_version = abi_version + so_version = stable_so_version endif # first build static lib diff --git a/mk/rte.lib.mk b/mk/rte.lib.mk index 655a1b143..8ab852a3c 100644 --- a/mk/rte.lib.mk +++ b/mk/rte.lib.mk @@ -11,14 +11,16 @@ EXTLIB_BUILD ?= n # VPATH contains at least SRCDIR VPATH += $(SRCDIR) -ifneq ($(shell grep -s "^DPDK_" $(SRCDIR)/$(EXPORT_MAP)),) LIBABIVER := $(shell cat $(RTE_SRCDIR)/ABI_VERSION) -else ifeq ($(LIBABIVER),) +SOVER := $(basename $(LIBABIVER)) +ifeq ($(shell grep -s "^DPDK_" $(SRCDIR)/$(EXPORT_MAP)),) # EXPERIMENTAL ABI is versioned as 0.major+minor, e.g. 0.201 for 20.1 ABI -LIBABIVER := 0.$(shell cat $(RTE_SRCDIR)/ABI_VERSION | tr -d '.') +LIBABIVER := 0.$(shell echo $(LIBABIVER) | tr -d '.') +SOVER := 0.$(shell echo $(SOVER) | tr -d '.') endif ifeq ($(CONFIG_RTE_BUILD_SHARED_LIB),y) +SONAME := $(patsubst %.a,%.so.$(SOVER),$(LIB)) LIB := $(patsubst %.a,%.so.$(LIBABIVER),$(LIB)) ifeq ($(EXTLIB_BUILD),n) CPU_LDFLAGS += --version-script=$(SRCDIR)/$(EXPORT_MAP) @@ -74,7 +76,7 @@ NO_UNDEFINED := -z defs endif O_TO_S = $(LD) -L$(RTE_SDK_BIN)/lib $(_CPU_LDFLAGS) $(EXTRA_LDFLAGS) \ - -shared $(OBJS-y) $(NO_UNDEFINED) $(LDLIBS) -Wl,-soname,$(LIB) -o $(LIB) + -shared $(OBJS-y) $(NO_UNDEFINED) $(LDLIBS) -Wl,-soname,$(SONAME) -o $(LIB) O_TO_S_STR = $(subst ','\'',$(O_TO_S)) #'# fix syntax highlight O_TO_S_DISP = $(if $(V),"$(O_TO_S_STR)"," LD $(@)") O_TO_S_DO = @set -e; \ @@ -133,6 +135,7 @@ $(RTE_OUTPUT)/lib/$(LIB): $(LIB) $(Q)cp -f $(LIB) $(RTE_OUTPUT)/lib ifeq ($(CONFIG_RTE_BUILD_SHARED_LIB),y) $(Q)ln -s -f $< $(shell echo $@ | sed 's/\.so.*/.so/') + $(Q)ln -s -f $< $(shell echo $@ | sed 's/\.so.*/.so.$(SOVER)/') endif # -- 2.23.0
