OK , I read them as you told me . and in the README file it is mentioned how to compile it . Now , however , I have another problem which is more complicated than the first :

During the building process in cygwin , I got this error :

I got the same problem, the following command fixed it:

$ cd /tmp/zlib-1.2.11                                                                       
$ sed -i 's/defined(_WIN32) || defined(__CYGWIN__)/defined(_WIN32)/g' gzguts.h
