Background:
My Linux idiots, because learning embedded qt development, need to use opencv, opencv cross-compilation has been compiled, but normal virtual machine environment opencv compilation has been stuck in the libQt5Core. So. 5.6.0: could not read symbols: the File in wrong format
Using the virtual machine qt5.6 compiled environment is embedded development board manufacturers, the dependence of opencv library is my own compilation, using cmake - GUI configuration
