Before starting to build RIVET, you will need to have the following installed:
- A C++ compiler (g++ or clang are what we use)
- CMake
- Qt 5
- Boost (including boost serialization; version 1.60 or newer required)
Below we give step-by-step instructions for installing these required dependencies and building RIVET on Ubuntu and Mac OS X. Building RIVET on Windows is not yet supported (we are working on this), but it is possible to build RIVET using the Bash shell on Windows 10.
To install dependencies on Ubuntu, we suggest that you first upgrade to Ubuntu 16.10; the Ubuntu 16.04 package manager only installs Boost 1.58, whereas RIVET requires Boost version 1.60 or higher.
On Ubuntu 16.10, installation of dependencies should be relatively simple:
sudo apt-get install cmake qt5-default qt5-qmake qtbase5-dev-tools libboost-all-dev
After cloning to $RIVET_DIR:
cd $RIVET_DIR
mkdir build
cd build
cmake ..
make
cd ..
qmake
make
You may see compiler warnings during either of the make executions.
These can safely be ignored.
After this, you will have two executables built: the viewer (RIVET), and the computation engine (rivet_console).
It is then necessary to move or symlink the console into the same folder where the viewer was built. On Ubuntu and most other systems:
ln -s build/rivet_console
In the future, all these steps will be automated so that a single cmake build will create both executables, and put everything in the right place.
First, ensure you have the XCode Command Line Tools installed by running:
# only needed if you've never run it before, (running it again doesn't hurt anything)
# installs XCode Command Line Tools
xcode-select --install
If a popup window appears, click the "Install" button, and accept the license agreement.
Next, install XCode from the App Store, if you've not done so already. You will also need accept the license agreement for XCode, which you can do from the command line by running:
sudo xcodebuild -license
To install the remaining packages, we recommend using the package manager Homebrew. To install Homebrew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Now install cmake, qt5, and boost:
brew install cmake qt5 boost
Please note that, as of the time of writing, brew installs qmake in a version-specific folder under
/usr/local/Cellar/qt5/[my_version_#]/bin, and does not add it to your PATH. You can find
the folder where qt5 is installed using this command:
brew info qt5 | grep Cellar | cut -d' ' -f1
In fact, let's store that in a variable so we can use it below:
export QT_BASE=`brew info qt5 | grep Cellar | cut -d' ' -f1`
Finally, in order to ensure that qmake can find where boost is installed, add the following lines to the bottom of the file RIVET.pro, changing the paths in the last three lines, if necessary, to match the location and version of your copy of Boost.
CONFIG += c++11
QMAKE_CFLAGS += -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9
QMAKE_CXXFLAGS += -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9
LIBS += -L"/usr/local/Cellar/boost/1.63.0/lib"
INCLUDEPATH += "/usr/local/Cellar/boost/1.63.0/include"
LIBS += -L"/usr/local/Cellar/boost/1.63.0/lib" -lboost_random
After cloning to $RIVET_DIR:
cd $RIVET_DIR
mkdir build
cd build
cmake ..
make
cd ..
$QT_BASE/bin/qmake
make
You may see compiler warnings during either of the make executions.
These can safely be ignored.
After this, you will have two executables built: the viewer (RIVET.app), and the computation engine (rivet_console).
It is then necessary to move or symlink the console into the same folder where the viewer was built:
cd RIVET.app/Contents/MacOS
ln -s ../../../build/rivet_console
In the future, all these steps will be automated so that a single cmake build will create both executables, and put everything in the right place.
Our experience has been that if Homebrew is installed before XCode, then running qmake during the build process returns an error:
Project ERROR: Could not resolve SDK Path for 'macosx'
To solve the problem, try running:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
First, ensure that you have the Windows 10 Creators Update. Then activate the Windows 10 Bash Shell. This will provide a Bash shell with Ubuntu 16.04 inside of Windows 10.
Open the Bash shell and install dependencies. Use the following command to install cmake, a compiler, and Qt5:
sudo apt-get install cmake build-essential qt5-default qt5-qmake qtbase5-dev-tools
The Ubuntu 16.04 repositories include Boost 1.58, but RIVET requires Boost 1.60 or newer. The following instructions install Boost 1.64 into /usr/local/boost_1_64_0/:
-
Download a compressed Boost file into your home directory:
cd ~ wget "https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.bz2" -
Unpack Boost to
/usr/local/:cd /usr/local sudo tar xvjf ~/boost_1_64_0.tar.bz2 cd boost_1_64_0 -
Setup Boost:
sudo ./boostrap.sh --prefix=/usr/local sudo ./b2 sudo ./b2 install -
Return to home directory and delete the compressed Boost file.
cd ~ rm boost_1_64_0.tar.bz2
In order to use the RIVET viewer, you must install an X server such as Xming.
It is also necessary to set two environment variables, as follows:
export LD_LIBRARY_PATH=/usr/local/boost_1_64_0/stage/lib/:$LD_LIBRARY_PATH
export DISPLAY=:0
These environment variables will be reset when you close the Bash shell. To avoid having to run the two lines above when you reopen the shell, add these lines to the end of the file ~/.bashrc.
You are now ready to build RIVET. Follow the instructions in the section of this readme under the heading Building on Ubuntu: Building RIVET.
We welcome your contribution! Code, documentation, unit tests, interesting sample data files are all welcome!
Before submitting your branch for review, please run the following from the top level RIVET folder you cloned from Github:
clang-format -i **/*.cpp **/*.h
This will format the source code using the project's established source
code standards (these are captured in the .clang-format file in the
project root directory).
