Error building coroutine_echo_client on Ubuntu 14.04.1

I got this error while running “make all”:

Steps followed:

git clone git@github.com:maidsafe/MaidSafe
git -C MaidSafe submodule update --init
sudo ln -s /usr/bin/gcc-4.8 /usr/bin/gcc
sudo ln -s /usr/bin/g+±4.8 /usr/bin/g++

Reverted Arch specific patch as sugested here: Make error building on Ubuntu 14.04

vim MaidSafe/cmake_modules/add_boost.cmake

Removed line:
string(REGEX MATCH “[0-9]+\.[0-9]+\.[0-9]+” ToolsetVer “{CMAKE_CXX_COMPILER_VERSION}") Replaced with: string(REGEX MATCH "[0-9]+\\.[0-9]+" ToolsetVer "{CMAKE_CXX_COMPILER_VERSION}”)
cmake -HMaidSafe -Bbuild_maidsafe -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=gcc-4.8 -DCMAKE_CXX_COMPILER=g+±4.8

cd build_maidsafe && cmake .
make all

Cmake version:

The issue persists compiling with gcc-4.8.4 or gcc-4.9 or clang 3.5 on Ubuntu x64 in a virtual machine. Any ideas on what is causing this issue?

I don’t believe ARM is supported with Boost.Context. That support comes in Boost v1.58 I believe, someone committed some patches there a few weeks ago.
