Dependencies:

• cmake >= 3.1.0
• zlib
• qt >= 5.5

• Python3.5+

  • virtualenv

• OpenSSL >= 1.0.0, < 1.1.0
• clang-tidy
• clang-format
• libclang-common-dev

Caveats: qt >= 5.6 is required if you want to rearrange tabs using drag&drop.

Optional dependencies needed for running tests:

• gtest

Additional Windows dependency (only needed to compile OpenSSL):

• perl

If your distribution has -dev or -devel packages, you'll also need ones corresponding to the dependencies above.

On Ubuntu it can be done like this:

apt-get install cmake zlib1g-dev qtbase5-dev g++ python3 python3-venv python3-dev libffi-dev libssl-dev clang-tidy-4.0 clang-format-4.0 libclang-common-4.0-dev

To build :

$ mkdir build
$ cd build
$ cmake -D CMAKE_BUILD_TYPE=Release ..
$ make

To install [which is optional], use :

$ make install

To run Veles from build directory we recommend creating virtualenv for Veles:

$ python3 -m venv ~/venv/veles
$ . ~/venv/veles/bin/activate
(veles) $ pip install -r ../python/requirements.txt

Then to run Veles you will need to activate the venv before running Veles:

$ . ~/venv/veles/bin/activate
(veles) $ ./veles

If you want to install to a non-default directory, you'll also need to pass it as an option to cmake before building, eg.:

$ cmake -D CMAKE_INSTALL_PREFIX:PATH=/usr/local ..

Python tests dependencies:

• git
• Python2.7

• Python packages:

  • pip
  • tox>=2.4.0

On Ubuntu it can be done like this:

apt-get install git python2.7 python2.7-dev python3-pip
pip3 install tox>=2.4.0

On Windows if you want to avoid compiling OpenSSL everytime you clean build directory you can store libeay32.dll and ssleay32.dll in some directory, and pass it to cmake as OPENSSL_DLL_DIR.
