Question

我遇到与this thread类似的错误。我在Python中输入错误如下：

File＆＃34; /home/cayman/multiviewer/src/analyzer/analyzer.py" ;,第23行，在 from wrapped.libraries.IpMetrics import IpMetrics ImportError：/home/cayman/multiviewer/src/analyzer/wrapped/libraries/IpMetrics.so: 未定义的符号： Z15calcTimevalDiff7timevalS

以下是我的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

    $(CC) $(CPPFLAGS) -I$(PYTHON_INCLUDE) -I$(BOOST_INC) -o $(obj_dir)/boost_$(MODULE_NAME).o boost_$(MODULE_NAME).cpp


    $(CC) -shared -Wl,--export-dynamic \

    -lpython$(PYTHON_VERSION) -o $(lib_dir)/$(MODULE_NAME).so

clean:

我的软件编译和构建如下：

知道可能出现什么问题吗？
