## System compatibility

You need a C++14 compiler.
You need a C++17 compiler.

All libraries are optional but you will be missing features if the libraries
aren't present. The configure script will tell you what's present and what's
not.

### Ubuntu 16.04 / gcc 5

The default C++ compiler on Ubuntu 16.04 will not compile libCVD because of
a [bug in the standards compliance of the compiler.](https://stackoverflow.com/questions/34280729/throw-in-constexpr-function). If you want to use libcvd,
you will need to install a newer compiler. The easiest eay is to add the
[toolchain test PPA](https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test):

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-7

Now you can build libcvd with either:

CXX=g++-7 ./configure
make
or

mkdir build
cd build
CXX=g++-7 cmake -DCMAKE_BUILD_TYPE=Release ..
make
