我要疯了...
我正在开发一个程序，用于从带有OpenNI和NiTE的Xtion Primesense传感器中读取关节坐标。我把程序分为三部分。主传感器sensorOpenNI.hpp和sensorOpenNI.cpp。现在，将各部分链接在一起时，我会遇到很多错误，说存在对某些NiTE功能的未定义引用。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：

collect2：ld返回1退出状态
我这样叫g ++：
g++ -o test mainSensor.cpp sensorOpenNI.cpp -I Include/
最佳答案
尝试像这样复制库libOpenNI2.so和libNiTE2：
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
然后做
须藤ldconfig
现在通过添加-lOpenNI2 -lNiTE2来编译程序
关于c++ - OpenNI链接错误，很多 undefined reference ，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/15803322/
