Linux Compilation Tutorial

The tutorial requires some basic knowledge about Linux OS!

Though it is unclear why it needs to run in Linux... Anyway in case somebody needs it_(:з」∠)_

If you meet any other problems, please feel free to submit issue to us.

Download and Compile 3rd-party Libraries

Opencv

Please search the tutorial and install. Nothing to mention. The version 4.5.3 is confirmed to be able to use. Other versions should be OK as well, but 4.5.3 is recommended to keep it the same as the project and avoid some unnecessary problems. Installing Opencv itself is enough. opencv_contrib is not required.

PaddleOCR

Use a hacked version: https://github.com/MistEO/PaddleOCR.
Refer to this tutorial.
Download extra dependencies for PaddlePaddle. Both avx and mkl are recommended, which can improve the efficiency of calculation. However, if your CPU does not support them, you can choose compatible version of either noavx or openblas (new CPUs should support them, even AMD). cuda and cudnn are GPU libraries, but I haven't tried it on PaddleOCR yet. Feel free to try it out.
If cmake cannot find Opencv, you can try editing the finding path of Opencv.
If you are using MKL version, you can change the MKL Macro to true to improve performance.

Compilation flags for your reference

cmake ../ -DPADDLE_LIB=/your_path/paddle_inference/ -DOpenCV_DIR=/your_path_to_opencv/ -DWITH_STATIC_LIB=OFF -DBUILD_SHARED=ON
# If your device does not support MKL, you can add `-DWITH_MKL=OFF` flag, and download corresponding PaddlePaddle version.

zlib

In Ubuntu:

sudo apt update && sudo apt install zlib1g-dev
sudo ldconfig

If zlib does not exist in other distribution, you can try compiling from source.

MeoAssistant

Copy the compiled 3rd-party library to 3rdparty/lib or change CMakeLists.txt to indicate 3rd-party library path manually.
The header files in 3rdparty/include/opencv is version 4.5.3. If you are using other versions, please notice there may be conflicts in header files (you can simply replace them with your opencv header files).
Install adb, and change resource/config.json - Custom.adb.path to "adb"
Copy resource files to the same folder of libMeoAssitant.so.

cd tools
sh ./update_resource.sh <YourBuildDir>

Call by Python interface or C interface, requiring you to write some code.
cmake can compile a demo for testing by adding -DBUILD_TEST=ON flag
