If you re using ZLib in your project  then you need to find     if 1   in zconf h and replace uncomment  it with     if HAVE UNISTD H       the rest of the line   If it isn t ZLib I guess you should find some alternative way to do this  GL

The  uni  in unistd stands for  UNIX  - you won t find it on a Windows system   Most widely used  portable libraries should offer alternative builds or detect the platform and only try to use headers functions that will be provided  so it s worth checking documentation to see if you ve missed some build step - e g  perhaps running  make  instead of loading a   sln  Visual C   solution file   If you need to fix it yourself  remove the include and see which functions are actually needed  then try to find a Windows equivalent
