Python boost程序上的导入错误

我有一个类似于中的错误。我在Python中遇到如下导入错误：

文件“/home/cayman/multiviewer/src/analyzer/analyzer.py”，第23行， 在里面 从wrapped.libraries.IpMetrics import IpMetrics ImportError:/home/cayman/multiviewer/src/analyzer/wrapped/libraries/IpMetrics.so： 未定义的符号：Z15calcTimevalDiff7timevalS

下面是我的makefile

MODULE_NAME=IpMetrics
CPPFLAGS=-O2 -Wall -fPIC -c -std=c++11 -I../src
CC=g++-4.9
o_dir ?= "../../wrapped/"
lib_dir := $(o_dir)libraries/

PYTHON_VERSION = 2.7
PYTHON_INCLUDE = /usr/include/python$(PYTHON_VERSION)

ifeq "$(wildcard $(/usr/lib/boost-gcc49) )" ""
    BOOST_INC = /usr/lib/boost-gcc49/include
    BOOST_LIB = /usr/lib/boost-gcc49/lib
else
    BOOST_INC = /usr/include
    BOOST_LIB = /usr/lib
endif

all:
    $(eval obj_dir=$(o_dir)objects)
    $(eval lib_dir=$(o_dir)libraries)
    $(CC) $(CPPFLAGS) -o $(obj_dir)/IpPacketMetricsBase.o ../src/IpPacketMetricsBase.cpp

clean:

我的软件编译和构建如下：

：~/multiviewer/src/analyzer/cpp/IpMetrics$make g++-O2-Wall-fPIC-c -std=c++11-I../src-o“../../wrapped/”objects/IpPacketMetricsBase.o../src/IpPacketMetricsBase.cpp g++-O2-Wall-fPIC-c-std=c++11 -I../src-o“../../wrapped/”对象/IpPacketJitterDelayVariation.o../src/IpPacketJitterDelayVariation.cpp g++-O2-Wall-fPIC-c -std=c++11-I../src-o“../../wrapped/”对象/IpPacketJitterCumulative.o ../src/IpPacketJitterCumulative.cpp g++-O2-Wall-fPIC-c-std=c++11 -I../src-o“../../wrapped/”objects/IpPacketMetricsUtil.o../src/IpPacketMetricsUtil.cpp g++-O2-Wall-fPIC-c-std=c++11 -I../src-o“../../wrapped/”objects/IpPacketLossMetrics.o../src/IpPacketLossMetrics.cpp g++-O2-Wall-fPIC-c-std=c++11 -I../src-o“../../wrapped/”objects/IpPacketMetrics.o../src/IpPacketMetrics.cpp g++-O2-Wall-fPIC-c-std=c++11-I../src -I/usr/include/python2.7-I/usr/lib/boost-gcc49/include-o“../../wrapped/”objects/boost\u IpMetrics.o boost\u IpMetrics.cpp g++ -shared-Wl，--export dynamic\“../../wrapped/”objects/boost_IpMetrics.o\ “../../wrapped/”对象/IpPacketMetricsBase.o\ “../../wrapped/”对象/IpPacketJitterDelayVariation.o\ “../../wrapped/”对象/IpPacketJitterCumulative.o\ “../../wrapped/”对象/IpPacketLossMetrics.o\ “../../wrapped/”对象/IpPacketMetrics.o\ -lpcap-lboost_thread-L/usr/lib/boost-gcc49/lib-lboost_python-L/usr/lib/python2.7/config\ -lpython2.7-o“../../wrapped/”库/IpMetrics.so

知道有什么问题吗？

链接和运行时很可能出现不兼容的boost版本。通过修正env，确保使用相同的boost库；请尝试导出LD\u LIBRARY\u PATH=/usr/lib/boost-gcc49/lib:$LD\u LIBRARY\u PATH。谢谢您的建议。我试着这么做，并做了

，但在链接和运行时，几乎没有改变不兼容的boost版本。通过修正env，确保使用相同的boost库；请尝试导出LD\u LIBRARY\u PATH=/usr/lib/boost-gcc49/lib:$LD\u LIBRARY\u PATH。谢谢您的建议。我试着这么做，并做了

make

，但没有任何改变
