I installed yesterday Eclipse Kepler and worked so far with Juno (3.8.1). I am using MinGW64 as c++ compiler.
In principle it seems to work so far. However eclipse complains that the MinGW toolchain is not supported by the systems (MinGW is in the path), although if I build a sample project it works. Juno never complained about that.
The problem is just annoying and does not seems to influence the work but anyhow I want to get rid of that.
