Problem running demo: procedure entry point deflateSetHeader could not be located

[pbrown12303]

I have installed go-gtk and the gtk library. When I try to run the demo I get:

The procedure entry point deflateSetHeader could not be located in the dynamic link library C:\msys64\mingw64\bin\libgio-2.0-0.dll

Any ideas as to how to resolve this?

Maybe you have another zlib1.dll which is not expected version from libgio. Try to find with where zlib1.dll.
