Retrieving OpenEB source code

Clone the GitHub repository in a path that doesn't contain any spaces:

Note

If you clone into a path that contains spaces, you will get an error when sourcing. This is because the environment variables cannot be set.

Go into path/to/openeb/build/utils/scripts/setup_env.sh.

Either change all to \ :

export PATH=/Users/jozseflurvig/GitHub\ Projects/openeb/build/bin:$PATH
export MV_HAL_PLUGIN_PATH=/Users/jozseflurvig/GitHub\ Projects/openeb/build/lib/metavision/hal/plugins
export PYTHONPATH=/Users/jozseflurvig/GitHub\ Projects/openeb/build/py3:/Users/jozseflurvig/GitHub\ Projects/openeb/sdk/modules/core_ml/python/pypkg:/Users/jozseflurvig/GitHub\ Projects/openeb/sdk/modules/core/python/pypkg::/Users/jozseflurvig/GitHub\ Projects/openeb/utils/python:/Users/jozseflurvig/GitHub\ Projects/openeb/utils/ci:$PYTHONPATH
export HDF5_PLUGIN_PATH=/Users/jozseflurvig/GitHub\ Projects/openeb/build/lib/hdf5/plugin
exec "$@"

or put the whole path in quotation marks:

export PATH="/Users/jozseflurvig/GitHub Projects/openeb/build/bin":$PATH
export MV_HAL_PLUGIN_PATH="/Users/jozseflurvig/GitHub Projects/openeb/build/lib/metavision/hal/plugins"
export PYTHONPATH="/Users/jozseflurvig/GitHub Projects/openeb/build/py3":"/Users/jozseflurvig/GitHub Projects/openeb/sdk/modules/core_ml/python/pypkg":"/Users/jozseflurvig/GitHub Projects/openeb/sdk/modules/core/python/pypkg"::"/Users/jozseflurvig/GitHub Projects/openeb/utils/python":"/Users/jozseflurvig/GitHub Projects/openeb/utils/ci":$PYTHONPATH
export HDF5_PLUGIN_PATH="/Users/jozseflurvig/GitHub Projects/openeb/build/lib/hdf5/plugin"
exec "$@"
git clone git@github.com:prophesee-ai/openeb.git

Prerequisites

Install the following dependencies:

brew update
brew install cmake libusb boost pybind11 opencv glfw

Compilation

Create and open the build directory in OPENEB_SRC_DIR

mkdir build && cd build

Generate the makefiles using CMake

cmake .. -DBUILD_TESTING=OFF

Compile

cmake --build . --config Release -- -j 4

To use OpenEB directly from the build folder, you need to update some environment variables using this script (which you may add to your ~/.bashrc to make it permanent):

source utils/scripts/setup_env.sh

Necessary changes to the code

In sdk/modules/ui/cpp/src/base_window.cpp in the LoadShaders() function, change version 310 es to version 330 (there are two occurencies in the file).

In CMakeLists.txt file (in root folder) add:

if (${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
    include_directories(/usr/local/include)
    link_directories(/usr/local/lib)
    
    include_directories(/opt/homebrew/include)
    link_directories(/opt/homebrew/lib)
endif()

and comment this line:

link_libraries(stdc++fs)
