Problems install protobuf using cmake

Question

I have been trying to install imposm.parser, that drove me crazy. After days online, I managed to install it on mac.
However, I have been trying to install it on windows, but before that, it is required to install google's protobuf. This is also not going easy at all. I managed to progress a bit, but now I am stuck at this point when nothing is helping.
The instructions I'm following are here:
CMake Configuration
I have been tryin through cmd, cygwin and Developer Command Prompt for VS2015, with no hope. The output is as follows:

Developer Command Prompt - VS2015

My question is: How to solve this problem? And, is there an easier way to install protobuf and imposm.parser on windows?

Answer 1

_deflate sounds like a function from some compression library. Indeed it is used in a class called GzipOutputStream. Are you using the link flags for all dependencies of protobuf?

There is also a machine type mismatch. Maybe you are trying to link 32bit libraries into a 64 bit executable.
