includeos
g++ 7.0 / clang 5.0 required for building dev
We've bumped C++ version to C++17 on the dev branch, which places new constraints on clang and gcc version. Building IncludeOS will now require clang++-5.0, and building the unit tests with gcc will require g++-7.0. The unit tests will also build fine with clang++-5.0, but as the unit tests are a normal host binary it will need access to a recent c++ standard library on the host. Installing g++-7.0 will provide this.
Clang 5.0 is available in universe on ubuntu 16.04 LTS, but g++-7.0 is not. We'll need to either update our install script to provide these dependencies or ditch the install script and update documentation.
@alfred-bratterud I have tried to install IncludeOS on Ubuntu 14.04 and I have faced an error which was posted #1654 .
Then, I tried with Ubuntu 16.04 and this is the problem I am facing. Both the Ubuntu installations are on Virtualbox and gcc/g++ version is 7.2.0

IncludeOS will be installed with the following options:
Env variable Description Value
------------ ----------- -----
INCLUDEOS_SRC Source dir of IncludeOS /home/karra/IncludeOS
INCLUDEOS_PREFIX Install location /usr/local/includeos
ARCH CPU Architecture x86_64
INCLUDEOS_ENABLE_TEST Enable test compilation OFF
Is this correct [Y/n]?
Running install_from_bundle.sh (expect up to 3 minutes)
Best guess for compatible compilers: clang++ / clang

Sorry <<< Could not install from bundle.`
When I tried to set the environment variable (as export CC=/usr/bin/gcc and
export CXX=/usr/bin/g++ in .bashrc), the clang-5.0 -> INSTALLED is changing to clang-gcc -> MISSING and some other errors are showing up.
Please help with the installation.
@karra88 try this:
export CC=clang-5.0
export CXX=clang++-5.0
./install.sh
