我正在使用以下命令创建.so文件：
用于创建.o文件
g++ -c -fPIC -I/usr/include/python2.7 -I/home/user/Desktop/AutoTest/SDKTestSuite/ -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I. -I. SDKTestSuite.cpp
用于创建.so文件
g++ -shared -o SDKTestSuite.so SDKTestSuite.o -L/usr/lib/i386-linux-gnu -lpython2.7 -lDijSDK -leventflag -lQtGui -lQtCore -L/usr/lib/i386-linux-gnu/cameras/ -lsynthcam -luusb
在创建.so文件后，如果我使用ldd命令显示.so文件的依赖项，则提供以下输出

问题是，我在创建SDKTestSuite.so文件时包含库文件libsynthcam.so和libuusb.so文件。为什么这些摄像机名称没有显示在ldd命令的输出中。
如何使ldd命令显示这些库文件？
