Question

我开车疯了...... 我正在制定一个程序，用OpenNI和NiTE从Xtion Primesense传感器中读出联合坐标。我分三部分得到了程序splittet。 Main，sensorOpenNI.hpp和sensorOpenNI.cpp。现在，在将各个部分链接在一起时，我收到很多错误，说有一些NiTE函数的未定义引用。我正在使用Kubuntu和g ++。 NiTE和OpenNI库位于名为Include的目录中...... 这是错误消息：

我这样称为g ++：

g++ -o test mainSensor.cpp sensorOpenNI.cpp -I Include/

尝试复制libOpenNI2.so和libNiTE2这样的库：

sudo cp ./OpenNI-Linux-x86-2.2/Redist/libOpenNI2.so /usr/local/lib 
sudo cp ./NiTE-Linux-x86-2.2/Redist/libNiTE2.so /usr/local/lib

然后呢 sudo ldconfig 现在通过添加-lOpenNI2 -lNiTE2

来编译程序

OpenNI链接错误，许多未定义的引用
