Welcome to the forge wiki!

Document Outline:

GLFW or SDL2
freetype
boost - not a runtime dependency.
FreeImage - (optional).
fontconfig on Linux and OSX.
Documentation Generation (preferred & recommended version of python is 3.*)
- Doxygen
- Sphinx with extensions: Breathe, recommonmark

Linux/Unix: Dependencies should be available via respective package managers. Windows: We recommend vcpkg.

$ git clone https://github.com/arrayfire/forge.git

CMake Options:

¹ Defaults to Debug for cloned repository, Release otherwise.
² Turned ON if doxygen is found.
³ CPU examples are built always. CUDA & OpenCL examples are built if CUDA toolkit and OpenCL libraries are found.
⁴ Currently, only OpenGL available.
⁵ SDL2 is the only current alternative.
⁵ FreeImage support only turned ON if dev package is found.

Microsoft Visual Studio 2017 or later
CMake v3.5.1 and above
vcpkg (latest version)

1. Configure

Dependency installation is also taken care of by the below cmake configure command.

cd forge
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 \
  -DCMAKE_TOOLCHAIN_FILE="<vcpkg_dir>\scripts\buildsystems\vcpkg.cmake" \
  -DVCPKG_MANIFEST_DIR=..\vcpkg ..

If you are building the CUDA examples with Visual Studio 2017 (v15.5 and above), you will need to point to the v140(or later) toolset during the configuration step:

cmake -Tv140 -G "Visual Studio 15 2017 Win64" \
  -DCMAKE_TOOLCHAIN_FILE="<vcpkg_dir>\scripts\buildsystems\vcpkg.cmake" ..

Follow the instructions from here to install v140 toolset in Visual Studio 2017.

2. Build ArrayFire

Once Forge has been configured, you may build Forge by opening the build\Forge.sln file in Visual Studio.

With latest master, there is no need to install dependencies manually. However, in the case your workflow is setup in such fashion do keep note of the following points.

Using freetype installed in vcpkg folder is sufficient for developement purposes. However, if the intention behind building forge is to create a custom package(using cpack), then we recommend using a static version of freetype that can be installed in vcpkg using the instructions from this page.
As of writing this page, there is an issue with freetype (dynamic library version) provided by vcpkg when we do the following: freetype link-library(lib file) is installed instead of the dll file. Until this is fixed upstream, the above mentioned work around can be employed to correctly package forge usign cpack.

install(FILES $<TARGET_FILE:Freetype::Freetype> ...)

The instructions are based on Ubuntu 16.04. Change the packages and package manager to the distro of your choice.

Required: gcc (>=4.7), g++, git (>=1.8), make, cmake(v3.5.1 and above)
Recommended: FreeImage (version 3), cmake-curses-gui

sudo apt-get install -y build-essential git cmake
sudo apt-get install -y cmake-curses-gui

sudo apt-get install -y libboost-all-dev libfontconfig1-dev libfreeimage-dev libglfw3-dev

Fontconfig package installs freetype as it's dependency.

cd /path/to/dir/forge
mkdir build && cd build && cmake ..
make -j8 # or number of threads of your choosing

The default installation prefix is /usr/local. That is, includes are installed to /usr/local/include, libs are installed to /usr/local/lib, and examples are installed to /usr/local/forge.

To change the install prefix use

cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install/dir

NOTE: If the default gcc on your machine is gcc >= 6.1 and you will have to do the following to build CUDA examples.

For example on archlinux, you'd have to install gcc version suitable for CUDA compilation from the Arch repositories and then run the followinng commad.

cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install/dir -DCUDA_HOST_COMPILER:FILEPATH=/usr/bin/g++-<compatible-version-number>

Then run make install (use sudo to install to system directories).

The instructions are based on OSX 10.9 or later.

Required: cmake(v3.5.1 and above)

brew install boost fontconfig freeimage glfw3

cd /path/to/dir/forge
mkdir build && cd build && cmake ..
make -j8 # or number of threads of your choosing

The default installation prefix is /usr/local. That is, includes are installed to /usr/local/include, libs are installed to /usr/local/lib, examples are installed to /usr/local/forge.

To change the install prefix use

cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install/dir

Make sure you are still in build folder, then:
