getting error while compiling vector_tile.cpp

I am getting the following error while compiling the vector_tile.cpp

Yes, this is needing fixed / known issue. Use clang++ instead of g++ for now to avoid the problem.

Now i am getting the following error when using clang++

What Mapnik version are you using? If v2.2.0, then try with the 2.3.x branch: https://github.com/mapnik/mapnik/tree/2.3.x

[veejaykrishnan]

Springmeyer,

              I have installed mapnik2.3.x version. Still i am getting the below error using compiler clang++.

[springmeyer]

looks like your problem is that -lprotobuf-lite is not working and protobuf is not getting linked. Slightly different than #58 but likely related, lets track at #58
