I am testing stereo algorithm in MiddleBury Stereo Evaluation
我在米德尔伯里立体评价中测试立体算法。
One of step was to compile the tools in code/as follows.
步骤之一是编写代码/如下所示的工具。
cd code/imageLib
make
cd ..
make
cd ..
In this case, there is error in first make as follows,
在这种情况下，首先出现的错误如下，
$ make
g++ -O3 -W -Wall -g -c -o ImageIOpng.o ImageIOpng.cpp
ImageIOpng.cpp:19:17: fatal error: png.h: No such file or directory
compilation terminated.
make: *** [<builtin>: ImageIOpng.o] Error 1
and, regarding second make,
关于第二次做,
$ make
g++ -g -O3 -W -Wall -IimageLib ii.cpp -LimageLib -lImg.i686-g -lpng -lz -o ii
/usr/lib/gcc/i686-pc-cygwin/5.4.0/../../../../i686-pc-cygwin/bin/ld: cannot find -lImg.i686-g
/usr/lib/gcc/i686-pc-cygwin/5.4.0/../../../../i686-pc-cygwin/bin/ld: cannot find -lpng
collect2: error: ld returned 1 exit status
make: *** [<builtin>: ii] Error 1
In previous step, make worked fine. So, what was the problem? I downloaded sample algorithm and did not edit/change contents in any file.
在前面的步骤中，使工作正常。那么，问题是什么呢?我下载了示例算法，并没有在任何文件中编辑/修改内容。

png.h is part of libpng16-devel and the specific include directory must be added to the include path of your project.
png。h是libpng16-devel的一部分，特定的包含目录必须添加到项目的include路径中。
$ cygcheck -l libpng16-devel |grep png.h
