找不到符号：预期用于：平面名称空间Mac OSX上CMAKE + Jamroot错误

Question

我有一个使用CMAKE创建的静态库，如下所示：

cmake_minimum_required(VERSION 3.4.1)

include(${CMAKE_CURRENT_SOURCE_DIR}/../../tools/cmake/CMakeLists.txt)

set(CMAKE_CXX_STANDARD 11)

if (NOT ANDROID)
    include_directories(${SHARED_THIRD_PARTY_DIR}/opencv/build/${BUILD_ARCHITECTURE}/include/)
endif (NOT ANDROID)

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include/)
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../Common/include)

add_library(
    Vision

    STATIC

    libVision/Blob.cpp
    libVision/BlobDetector.cpp
    libVision/Configuration.cpp
    libVision/DetectionBasedBlobTracker.cpp
    libVision/DocumentScanner.cpp
    libVision/FaceDetector.cpp
    libVision/MixtureOfGaussianBackgroundSubtraction.cpp
    libVision/Module.cpp
    libVision/MotionDetector.cpp
    libVision/MotionDetectorConfiguration.cpp
    libVision/MotionEstimatorL1Builder.cpp
    libVision/MotionEstimatorRansacL2Builder.cpp
    libVision/OfflineVideoStabilizer.cpp
    libVision/StreamingVideoStabilizer.cpp
    libVision/TimeLapser.cpp
    libVision/Tracker.cpp
    libVision/VideoStabilizerConfiguration.cpp
)

if (NOT ANDROID)
    enable_testing()
    #add_subdirectory(utVision)
endif (NOT ANDROID)

我正在使用Jamroot与静态库链接以创建.so文件：

import option ;
import feature ;
import python ;

if ! [ python.configured ]
{
    ECHO "notice: no Python configured in user-config.jam" ;
    ECHO "notice: will use default configuration" ;
    using python : 2.7 ;
}

# Platform architecture provided as an environment variable
import os ;
local ARCH = [ os.environ ARCH ] ;

# adjust this path to refer to the Boost root directory.

我加载了vision_library.so：

ImportError: dlopen(/../shared/Vision/pyVision/build/vision_library.so, 2): Symbol not found: __ZTVN6shared6vision12FaceDetectorE
  Referenced from: /../shared/Vision/pyVision/build/vision_library.so
  Expected in: flat namespace
 in /../shared/Vision/pyVision/build/vision_library.so

当我这样做时，在.a文件中找到了符号__ZTVN6shared6vision12FaceDetectorE：

nm build/native/libVision.a | grep __ZTVN6shared6vision12FaceDetectorE
0000000000003d78 S __ZTVN6shared6vision12FaceDetectorE

但是当我为nm做纳米操作时，我得到了：

nm /../shared/Vision/pyVision/build/vision_library.so | grep __ZTVN6shared6vision12FaceDetectorE
                 U __ZTVN6shared6vision12FaceDetectorE

不确定与.so链接后为何未定义。
