我编译了Caffe并运行命令行分类器。在编译之前，我使用Type Declaration检查了libpng版本并获得了：
libpng-config --ldflags --cflags版本1.6
但是，当我运行二进制文件时：
-L/work/zhang/common/tools/anaconda2/lib -lpng16
-I/work/zhang/common/tools/anaconda2/include/libpng16
然后我跑**libpng warning: Application was compiled with png.h from libpng-1.6.13**
**libpng warning: Application is running with png.c from libpng-1.2.49**
**libpng error: Incompatible libpng version in application and library**

，得到：
ldd <binary> | grep libpng如何使用相同版本的libpng强制它？
