Install Matlab with the provided installer, and then add the matlab-support package through the package-repositories. This basically takes care of setting all the compiler stuff, adding a launcher, etc. In order to make Matlab know about the shared object opengv.so, the path to opengv.so has to be added to LDLIBRARYPATH. Download OpenCV source. It can be from Sourceforge (for official release version) or from Github (for latest source). Extract it to a folder, opencv and create a new folder build in it. Open CMake-gui (Start All Programs CMake-gui) Fill the fields as follows (see the image below).

First, download the binaries for your operating system from the main github page:

Next, use the offline quick start guide located at the below link to complete the installation:

Opencv For Mac

See the platform-specific guides below, though the process is similar for each.This document corresponds to the example located online here and also to thebuilding_and_installing_viame example folder in a VIAME installation.

These instructions are designed to help build VIAME on a fresh machine. They were written forand tested on Ubuntu 16.04. Other Linux machines will have similar directions, but some steps(particularly the dependency install) may not be exactly identical. VIAME has also been builton: CentOS/RHEL 6+, Fedora 19+, and Ubuntu 16.04+ at a minimum.

Different Linux distributions may have different packages already installed, or mayuse a different package manager than apt, but on Ubuntu this should help to providea starting point:

And on CentOS 7:

If using VIAME_ENABLE_PYTHON, [Anaconda3 5.2.0](https://repo.anaconda.com/archive/) isrecommended, though you also try using native python, e.g. install python3, python3-dev,and numpy (or alternatively whatever python distribution you want to use),e.g.:

If using VIAME_ENABLE_CUDA for GPU support, you should install CUDA (version 9.0 or aboveis required, 9.2 or 10.1 being the tested versions. Other versions may work dependingon your build settings but are not officially supported yet):

Depending on the OS, the version of cmake you get with apt/yum/dnf is sometimes too old touse for building VIAME (you currently need at least CMake 3.11.3) so you may need to do amanual install of CMake. Go to the cmake website, https://cmake.org/download, and downloadthe appropriate binary distribution (for Ubuntu, this would be something likecmake-3.11.3-Linux-x86_64.sh, though newer versions will be out by the time you read this).Alternatively, download the source code, e.g. cmake-3.11.3.tar.gz, and build the binariesfrom source. To untar and build the source, use the following set of commands. Keep inmind that if you’re not using version 3.11.3, you’ll need to update the version number inthe below to match your downloaded version.

These instructions build the source code into a working executable, installs theexecutable into a personal system directory, and then lets the operating systemknow where that directory is so it can find cmake in the future in case/usr/local/bin isn’t in your PATH variable by default.

With all our dependencies installed, we need to build the environment for VIAMEitself. VIAME uses git submodules rather than requiring the user to grab eachrepository totally separately. To prepare the environment and obtain all thenecessary source code, use the following commands. Note that you can change srco whatever you want to name your VIAME source directory.

VIAME may be built with a number of optional plugins–VXL, Caffe, OpenCV,Scallop_TK, and Matlab–with a corresponding option called VIAME_ENABLE_[option],in all caps. For each plugin to install, you need a cmake build flag setting theoption. The flag looks like -DVIAME_ENABLE_OPENCV:BOOL=ON, of course changingOPENCV to match the plugin. Multiple plugins may be used, or none. If uncertain whatto turn on, it’s best to just leave the default enable and disable flags which willbuild most (though not all) functionalities. At a minimum, these are core componentswe recommend leaving turned on:

And a number of flags which control which system utilities and optimizations are built, e.g.:

And lastly, a number of flags which build algorithms with more specialized functionality:

VIAME can be built either in the source directory tree or in a seperate builddirectory (recommended). Replace “[build-directory]” with your location of choice,and run the following commands:

Depending on which enable flags you have set and your system configuration, you mayneed to set additional cmake variables to point to dependency locations. An exampleis below for a system with CUDA, Python, and Matlab enabled, though the versions areold. Please do not use CUDA 8 or python 2.7 anymore.

Building on Mac is very similar to Linux, minus the dependency install stage.Currently, we have only tested VIAME with OSX 10.11.5 and Clang 7.3.0, but otherversions may also work. Make sure you have a C/C++ development environment set up,install git, install cmake either from the source or a using a binary installer, andlastly, follow the same Linux build instructions above.

Building on windows can be very similar to Linux if using a shell like cygwin(https://www.cygwin.com/), though if not you may want to go grab the GUIersions of CMake (https://cmake.org/) and TortoiseGit (https://tortoisegit.org/).Currently Visual Studio 2015 and some versions of 2017 are supported.

First do a Git clone of the source code for VIAME. If you have TortoiseGit thisinvolves right clicking in your folder of choice, selecting Git Clone, and thenentering the URL to VIAME (https://github.com/VIAME/VIAME.git) and the locationof where you want to put the downloaded source code.

Next, do a git submodule update to pull down all required packages. In TortoiseGitright click on the folder you checked out the source into, move to the TortoiseGitmenu section, and select SubmoduleUpdate.

Next, install any required dependencies for items you want to build. If using CUDA,version 9.0 or above is desired, along with Python 3.6+. Other versions have yet tobe tested extensively, though may work. On Windows it can also be beneficial to useAnaconda to get multiple python packages. Boost Python (turned on by default whenPython is enabled) requires Numpy and a few other dependencies.

Finally, create a build folder and run the CMake GUI (https://cmake.org/runningcmake/).Point it to your source and build directories, select your compiler of choice, andsetup and build flags you want.

The biggest build issues on Windows arise from building VIAME in super-build andexceeded the windows maximum folder path length. This will typically manifest as builderrors in the kwiver python libraries. To bypass these errors you have 2 options:

1. Build VIAME in as high level as possible (e.g. C:/VIAME) or, alternatively

2. Set the VIAME_KWIVER_BUILD_DIR path to be something small outside of yoursuperbuild location, e.g. C:/tmp/kwiver to bypass path length limits. Thiis performed, for example, in the nightly build server cmake script as anexample https://github.com/VIAME/VIAME/blob/master/cmake/build_server_windows.cmake

If you already have a checkout of VIAME and want to switch branches orupdate your code, it is important to re-run:

gitsubmoduleupdate--init--recursive

After switching branches to ensure that you have on the correct hashesof sub-packages within the build (e.g. fletch or KWIVER). Very rarelyyou may also need to run:

gitsubmodulesync

Just in case the address of submodules has changed. You only need torun this command if you get a “cannot fetch hash #hashid” error. /waves-bundle-vst-plugin-download.html.

Super-Build Optimizations:

When VIAME is built as a super-build, multiple solutions or makefiles are generatedfor each individual project in the super-build. These can be opened up if you wantto experiment with changes in one and not rebuild the entire superbuild. VIAMEplaces these projects in [build-directory]/build/src/* and fletch in[build-directory]/build/src/fletch-build/build/src/*. You can also run ccmake orthe cmake GUI in these locations, which can let you manually change the build settingsfor sub-projects (say, for example, if one doesn’t build).

Python:

The default Python used is 3.6, though other versions may work as well. It depends onyour build settings, operating system, and which dependency projects are turned on.

Issue:

When compiling with CUDA turned on:

or similar.

Solution:

Express/Community versions of visual studio don’t ship with a file called vcvars64.batYou can add one manually be placing a bat file called ‘vcvars64.bat’ in folder‘Microsoft Visual Studio XX.0VCbinamd64’ for your version of visual studio. Thisfile should contain just a single line:

CALLsetenv/x64

Issue:

Boost fails to build early with error in *_out.txt:

Solution:

You are likely running out of memory and your C++ compiler is crashing (common on VMswith a small amount of memory). Increase the amount of memory availability to your VM orbuy a better computer if not running a VM with at least 1 Gb of RAM.

Issue:

On VS2015 with Python enabled: errorLNK1104:cannotopenfile'python27_d.lib'

Solution:

If you want to link against python in debug mode, you’ll have to build Python itselfto enable debug libraries, as the default python distributions do not contain them.Alternatively switch to Release or RelWDebug modes.

Issue:

Solution:

You have python installed, but not numpy. Install numpy.

Issue:

cannotfindcublas_v2.h or linking issues against CUDA

Solution:

VIAME contains a VIAME_DISABLE_GPU_SUPPORT flag due to numerous issues relating toGPU code building. Alternatively you can debug the issue (incorrect CUDA drivers forOpenCV, Caffe, etc…), or alternatively not having your CUDA headers set to be in your include path.

Opencv Mac Install

Issue:

Solution:

You have enabled CUDNN but the system is unable to locate CUDNN, as the message says.

Note CUDNN is installed seperately from CUDA, they are different things.

Install Opencv Mac Pip

You need to set the VIAME flag CUDNN_LIBRARY to something like /usr/local/cuda/lib64/libcudnn.so.Alternatively you can set CUDNN_ROOT to /usr/local/cuda/lib64 manually if that’s where you installed it.

Issue:

When VIAME_ENABLE_DOC is turned on and doing a multi-threaded build, sometimes the build fails.

Opencv Vs Matlab

Solution:

Run make-jX multiple times, or don’t run make-jX when VIAME_ENABLE_DOCS is enabled.

Issue:

CMake says it cannot find MATLAB

Solution:

Opencv Make Install

Make sure your matlab CMake paths are set to something like the following

Issue:

When PYTHON is enabled, getting the below error.

Solution:

raw_function.hpp doesn’t get installed for some reason on some systems. Manually copy it from:

[VIAME_BUILD]/build/src/fletch-build/build/src/Boost/boost/python/raw_function.hpp
