+
+Python bindings for C++ depthai-core library
+
+## Documentation
+
+Documentation is available over at [Luxonis DepthAI API](https://docs.luxonis.com/projects/api/en/latest/)
+
+## Installation
+
+Prebuilt wheels are available in [Luxonis repository](https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/)
+Make sure pip is upgraded
+```
+python3 -m pip install -U pip
+python3 -m pip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai
+```
+## Building from source
+
+### Dependencies
+ - cmake >= 3.4
+ - C++14 compiler (clang, gcc, msvc, ...)
+ - Python3
+
+Along these, dependencies of depthai-core are also required
+See: [depthai-core dependencies](https://github.com/luxonis/depthai-core#dependencies)
+
+
+### Building
+
+The first time you build, the repository submodules need be initialized:
+```
+git submodule update --init --recursive
+
+# Tip: You can ask Git to do that automatically:
+git config submodule.recurse true
+```
+
+Later submodules also need to be updated.
+
+#### Local build with pip
+To build and install using pip:
+```
+python3 -m pip install .
+```
+Add parameter `-v` to see the output of the building process.
+
+#### Wheel with pip
+To build a wheel, execute the following
+```
+python3 -m pip wheel . -w wheelhouse
+```
+
+#### Shared library
+To build a shared library from source perform the following:
+
+> ℹ️ To speed up build times, use `cmake --build build --parallel [num CPU cores]` (CMake >= 3.12).
+For older versions use: Linux/macOS: `cmake --build build -- -j[num CPU cores]`, MSVC: `cmake --build build -- /MP[num CPU cores]`
+
+```
+cmake -H. -Bbuild
+cmake --build build
+```
+To specify custom Python executable to build for, use `cmake -H. -Bbuild -D PYTHON_EXECUTABLE=/full/path/to/python`.
+
+#### Common issues
+
+* Many build fails due to missing dependencies. This also happens when submodules are missing or outdated (`git submodule update --recursive`).
+* If libraries and headers are not in standard places, or not on the search paths, CMake reports it cannot find what it needs (e.g. `libusb`). CMake can be hinted at where to look, for exmpale: `CMAKE_LIBRARY_PATH=/opt/local/lib CMAKE_INCLUDE_PATH=/opt/local/include pip install .`
+* Some distribution installers may not get the desired library. For example, an install on a RaspberryPi failed, missing `libusb`, as the default installation with APT led to v0.1.3 at the time, whereas the library here required v1.0.
+
+
+## Running tests
+
+To run the tests build the library with the following options
+```
+git submodule update --init --recursive
+cmake -H. -Bbuild -D DEPTHAI_PYTHON_ENABLE_TESTS=ON -D DEPTHAI_PYTHON_ENABLE_EXAMPLES=ON -D DEPTHAI_PYTHON_TEST_EXAMPLES=ON
+cmake --build build
+```
+
+Then navigate to `build` folder and run `ctest`
+```
+cd build
+ctest
+```
+
+To test a specific example/test with a custom timeout (in seconds) use following:
+```
+TEST_TIMEOUT=0 ctest -R "01_rgb_preview" --verbose
+```
+If `TEST_TIMEOUT=0`, the test will run until stopped or it ends.
+
+## Tested platforms
+
+- Windows 10, Windows 11
+- Ubuntu 18.04, 20.04, 22.04;
+- Raspbian 10;
+- macOS 10.14.6, 10.15.4;
+
+### Building documentation
+
+- **Using [Docker](https://docs.docker.com/) (with [Docker Compose](https://docs.docker.com/compose/install/))**
+
+     ```
+     cd docs
+     sudo docker-compose build
+     sudo docker-compose up
+     ```
+
+     > ℹ️ You can leave out the `sudo` if you have added your user to the `docker` group (or are using rootless docker).
+     Then open [http://localhost:8000](http://localhost:8000).
+
+     This docker container will watch changes in the `docs/source` directory and rebuild the docs automatically
+
+- **Linux**
+
+     First, please install the required [dependencies](#Dependencies)
+
+     Then run the following commands to build the docs website
+
+     ```
+     python3 -m pip install -U pip
+     python3 -m pip install -r docs/requirements.txt
+     cmake -H. -Bbuild -D DEPTHAI_BUILD_DOCS=ON -D DEPTHAI_PYTHON_BUILD_DOCS=ON
+     cmake --build build --target sphinx
+     python3 -m http.server --bind 0.0.0.0 8000 --directory build/docs/sphinx
+     ```
+
+     Then open [http://localhost:8000](http://localhost:8000).
+
+     This will build documentation based on current sources, so if some new changes will be made, run this command
+     in a new terminal window to update the website source
+
+     ```
+     cmake --build build --target sphinx
+     ```
+
+     Then refresh your page - it should load the updated website that was just built
+
+## Troubleshooting
+
+### Relocation link error
+
+Build failure on Ubuntu 18.04 ("relocation ..." link error) with gcc 7.4.0 (default) - [**issue #3**](https://github.com/luxonis/depthai-api/issues/3)
+   - the solution was to upgrade gcc to version 8:
+
+         sudo apt install g++-8
+         sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 70
+         sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-8 70
+### Hunter
+Hunter is a CMake-only dependency manager for C/C++ projects.
+
+If you are stuck with error message which mentions external libraries (subdirectory of `.hunter`) like the following:
+```
+/usr/bin/ld: /home/[user]/.hunter/_Base/062a19a/ccfed35/a84a713/Install/lib/liblzma.a(stream_flags_decoder.c.o): warning: relocation against `lzma_footer_magic' in read-only section `.text'
+```
+
+Try erasing the **Hunter** **cache** folder.
+
+Linux/MacOS:
+```
+rm -r ~/.hunter
+```
+Windows:
+```
+del C:/.hunter
+```
+or
+```
+del C:/[user]/.hunter
+```
+
+### LTO - link time optimization
+
+If following message appears:
+```
+lto1: internal compiler error: in add_symbol_to_partition_1, at lto/lto-partition.c:152
+Please submit a full bug report,
+with preprocessed source if appropriate.
+See <file:///usr/share/doc/gcc-10/README.Bugs> for instructions.
+lto-wrapper: fatal error: /usr/bin/c++ returned 1 exit status
+compilation terminated.
+/usr/bin/ld: error: lto-wrapper failed
+collect2: error: ld returned 1 exit status
+make[2]: *** [CMakeFiles/depthai.dir/build.make:227: depthai.cpython-38-x86_64-linux-gnu.so] Error 1
+make[1]: *** [CMakeFiles/Makefile2:98: CMakeFiles/depthai.dir/all] Error 2
+make: *** [Makefile:130: all] Error 2
+```
+
+One fix is to update linker: (In case you are on Ubuntu 20.04: `/usr/bin/ld --version`: 2.30)
+```
+# Add to the end of /etc/apt/sources.list:
+
+echo "deb http://ro.archive.ubuntu.com/ubuntu groovy main" >> /etc/apt/sources.list
+
+# Replace ro with your countries local cache server (check the content of the file to find out which is)
+# Not mandatory, but faster
+
+sudo apt update
+sudo apt install binutils
+
+# Should upgrade to 2.35.1
+# Check version:
+/usr/bin/ld --version
+# Output should be: GNU ld (GNU Binutils for Ubuntu) 2.35.1
+# Revert /etc/apt/sources.list to previous state (comment out line) to prevent updating other packages.
+sudo apt update
+```
+
+Another option is to use **clang** compiler:
+```
+sudo apt install clang-10
+mkdir build && cd build
+CC=clang-10 CXX=clang++-10 cmake ..
+cmake --build . --parallel
+```
+

+If you are stuck with error message which mentions external libraries (subdirectory of `.hunter`) like the following:
+```
+/usr/bin/ld: /home/[user]/.hunter/_Base/062a19a/ccfed35/a84a713/Install/lib/liblzma.a(stream_flags_decoder.c.o): warning: relocation against `lzma_footer_magic' in read-only section `.text'
+```
+
+Try erasing the **Hunter** **cache** folder.
+
+Linux/MacOS:
+```
+rm -r ~/.hunter
+```
+Windows:
+```
+del C:/.hunter
+```
+or
+```
+del C:/[user]/.hunter
+```
+
+### LTO - link time optimization
+
+If following message appears:
+```
+lto1: internal compiler error: in add_symbol_to_partition_1, at lto/lto-partition.c:152
+Please submit a full bug report,
+with preprocessed source if appropriate.
+See <file:///usr/share/doc/gcc-10/README.Bugs> for instructions.
+lto-wrapper: fatal error: /usr/bin/c++ returned 1 exit status
+compilation terminated.
+/usr/bin/ld: error: lto-wrapper failed

+```
+
+One fix is to update linker: (In case you are on Ubuntu 20.04: `/usr/bin/ld --version`: 2.30)
+```
+# Add to the end of /etc/apt/sources.list:
+
+echo "deb http://ro.archive.ubuntu.com/ubuntu groovy main" >> /etc/apt/sources.list
+
+# Replace ro with your countries local cache server (check the content of the file to find out which is)
+# Not mandatory, but faster
+
+sudo apt update
+sudo apt install binutils
+
+# Should upgrade to 2.35.1
+# Check version:
+/usr/bin/ld --version
+# Output should be: GNU ld (GNU Binutils for Ubuntu) 2.35.1
+# Revert /etc/apt/sources.list to previous state (comment out line) to prevent updating other packages.
+sudo apt update
+```
+
+Another option is to use **clang** compiler:
+```
+sudo apt install clang-10
+mkdir build && cd build
+CC=clang-10 CXX=clang++-10 cmake ..
+cmake --build . --parallel
+```
