Qt source build failure due to zlib

[Shidharth]

Hi All,

I have build qt 5.5 source in windows 8.1 with VS2010 x64 command prompt.

I tried to build with -system-zlib and -qt-zlib but not getting success with both ways.

I have faced below error, I have search over the forum and google but still I could not resolve this error. So, please help me to overcome this error.

@Shidharth You can't really use -system-zlib on windows since it doesn't usually have a system level zlib like osx and linux would.

If you have one installed you can try using that but I recommend just using -qt-zlib. That should work out of the box.
