Question

我尝试编译一些协议缓冲区文件，但出现以下错误。

[ 99%] Building CXX object CMakeFiles/lattice_planner.dir/modules/control/proto/lat_controller_conf.pb.cc.o
[100%] Linking CXX executable lattice_planner
CMakeFiles/lattice_planner.dir/modules/localization/proto/pose.pb.cc.o:(.bss+0x0): multiple definition of `apollo::localization::_Pose_default_instance_'

CMakeFiles/lattice_planner.dir/modules/common/localization/proto/pose.pb.cc.o:pose.pb.cc:(.text+0x4e8): first defined here

文件位于不同的文件夹中。我可以欺骗编译器GCC 5.4.0，以便没有多个定义吗？ CMakeLists.txt很大，因为我是手动添加所有源文件的。以下是一些代码段：

cmake_minimum_required(VERSION 3.5)
project(lattice_planner_src)
set(CMAKE_CXX_FLAGS "-Wall -std=c++11 -pthread")
find_package(Protobuf 3.7.1 REQUIRED)
if(PROTOBUF_FOUND)
    message ("log: protobuf found")
else()
    message (FATAL_ERROR "Cannot find Protobuf")
endif()

add_executable(lattice_planner  apollo-planner-test-main.cpp  ${SOURCE_FILES} ${HEADER_FILES} ${PTB_SRC} ${PTB_HDR})

target_include_directories (
    lattice_planner
    PUBLIC
    ${Boost_INCLUDE_DIRS} 
    ${PROJECT_SOURCE_DIR}
    ${PROTOBUF_INCLUDE_DIRS}
    ${EIGEN3_INCLUDE_DIR}
    /usr/local/include/qpOASES
    ${TinyXML2_INCLUDE_DIR}
    ${IPOPT_INCLUDE_DIRS}
    ${GLOG_INCLUDE_DIR}
    ctpl
)

target_link_libraries(lattice_planner
#    EIGEN
    ${TinyXML2_LIBRARIES}
#    ${GLOG_LIBRARY}
    ${IPOPT_LIBRARIES}
    ${Boost_LIBRARIES}
    ${PROTOBUF_LIBRARIES}
    /usr/local/lib/libglog.so.0
    /usr/local/lib/libqpOASES.a
    ${libgtest}
)

，而PTB_SRC和PTB_HDR是协议缓冲区的源和标头。该项目已经在带有MS项目的Windows上运行。不幸的是，我对此没有任何CMake。我也很高兴有想法和猜测。
