Wrong JPEG library version: library is 80, caller expects 62 //ubuntu版本太高
解决：
删除Ubuntu机器/usr/local/arm/4.5.1/arm-none-linux-gnueabi/sys-root/usr/lib下libjpeg.so libjpeg.so.8 libjpeg.so.8.0.2
拷贝Centos机器/usr/local/arm/4.3.2/arm-none-linux-gnueabi/libc/ usr/lib下libjpeg.so libjpeg.so.62 libjpeg.so.62.0.0
