+Check the gcc version you have installed (either using brew or previously installed). If the gcc version is 6.1 rather the expected 5.x by the default .yml configuration file, you have to modify the `<mynewt-src-directory>/repos/apache-mynewt-core/compiler/sim/compiler.yml` file to change the default `gcc v-5` defined there.
