Question

我想编译自己的动态链接库（.so），我们假设它的名称为worker_lib.so。
worker_lib.so依赖于其他动态链接库，例如libprotobuf-lite.so，libprotobuf.so和libprotoc.so。这些库位于目录（deps / lib）中。
如何编译我自己的动态链接库（worker_lib.so），包括依赖于它们的库（libprotobuf-lite.so，libprotobuf.so ...）
注意，我想用cmd或Makefile完成它。
总而言之，我想将ps-lite（https://github.com/dmlc/ps-lite）编译为.so。

相关帖子为Linking a shared library with another shared lib in linux。但是答案不能解决我的问题。

(info "ps start")
ifdef config
$(info "isconfig")
include $(config)
endif

include make/ps.mk

ifndef CXX
CXX = g++
endif

ifndef DEPS_PATH
DEPS_PATH = $(shell pwd)/deps
endif


ifndef PROTOC
PROTOC = ${DEPS_PATH}/bin/protoc
endif

INCPATH = -I./pssrc -I./include -I$(DEPS_PATH)/include
CFLAGS = -std=c++11 -msse2 -fPIC -O3 -ggdb -Wall -lpthread -finline-functions $(INCPATH) $(ADD_CFLAGS)


include make/deps.mk


lint:
    python tests/lint.py ps all include/ps pssrc

ps: build/libps.a
pslib: build/lib/worker_lib.so

PS_OBJS = $(addprefix build/, customer.o postoffice.o van.o meta.pb.o)
PS_LIB_SRC = $(addprefix build/, customer.o postoffice.o van.o meta.pb.o worker.o)

build/lib/worker_lib.so: $(PS_LIB_SRC)
    @mkdir -p build/lib
    $(CXX) -shared -Xlinker --unresolved-symbols=ignore-in-shared-libs $^ -o $@ $(CFLAGS)

build/libps.a: $(PS_OBJS)
    ar crv $@ $(filter %.o, $?)

build/%.o: pssrc/%.cc ${ZMQ} pssrc/meta.pb.h
    @mkdir -p $(@D)
    $(CXX) $(INCPATH) -std=c++0x -MM -MT build/$*.o $< >build/$*.d
    $(CXX) $(CFLAGS) -c $< -o $@

pssrc/%.pb.cc pssrc/%.pb.h : pssrc/%.proto ${PROTOBUF}
    $(PROTOC) --cpp_out=./pssrc --proto_path=./pssrc $<

-include build/*.d
-include build/*/*.d

我想make pslib编译worker_lib.so。但是当我make pslib时，我遇到以下问题： error information

other error informations

错误信息如下：

编译共享库，并通过Makefile在特定路径中链接到其他.so
