These instructions are for building FAST on Ubuntu 18.04 (previous versions, such as 16.04, are no longer supported).
For Ubuntu 20.04, please use GCC 8, and not GCC 9 which will cause OpenVINO build failure.

If you only want to test and use FAST, please download a release instead.

1. First, make sure you have all the tools necessary to download and compile the code:

sudo apt install cmake g++ git patchelf
sudo apt install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

2. Install OpenCL. Depending on which GPU/CPU you have and want to use install: NVIDIA CUDA Toolkit or AMD APP SDK or Intel OpenCL SDK.

3. FAST will download and build all other dependencies (Qt5, eigen, zlib, DCMTK) automatically. In order to get movie streaming to work with Qt, you need to install the following libraries:

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-bad1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-dev # Needed for movie streaming

By default, the WSI and RealSense modules are enabled by default, these require the following packages:

sudo apt install libopenslide-dev # Needed for WSI module
sudo apt install pkgconf libusb-1.0-0-dev # Needed for realsense

Important: Don't put the FAST code in a path with spaces, this will currently break the build.

FAST has several optional modules. These are enabled using cmake options named FAST_MODULE_. There are also several other options such as whether to build tests (FAST_BUILD_TESTS) or examples (FAST_BUILD_EXAMPLES).

git clone https://github.com/smistad/FAST.git
cd FAST
mkdir build
cd build
# Default cmake configuration. Options may be added like so: cmake .. -DFAST_BUILD_TESTS=OFF -DFAST_BUILD_EXAMPLES=ON
cmake ..

This will build all configured targets:

make -j8

Set CMAKE_INSTALL_PREFIX to where you want to install FAST on your drive. Then run:

make -j8 install

To build a debian package run:

make -j8 package

By enabling FAST_BUILD_DATA_DEB_PACKAGE, a separate package for the FAST test data set will also be created.

When you run cmake, the system may not find the OpenCL library, and you have to set it manually using cmake (e.g. cmake .. -DOpenCL_LIBRARY=/path/to/libOpenCL.so). The library is usually located in /usr/local/cuda/lib64/ for NVIDIA and /opt/amd-gpupro/lib/x864-linux-gnu/ if you use the AMD GPUPRO driver.

If you get the error saying something like "qfontengine_ft_p.h:56:22: fatal error: ft2build.h: No such file or directory" you have to install the fontconfig library "libfontconfig1-dev".

If you get an error like "ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && features.xkbcommon && libs.xcb' failed." This means you forgot to install the xcb an xkb libraries needed:

sudo apt install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev 

Note that you for some reason have to delete the folder build_folder/external/qt5/ and rebuild qt5 for this to take effect.

Next, you may run the tests to make sure the framework is working properly on your system. Instructions on how to do this can be found here.

Examples are found here.
