I wrote my inference codes according to this document.In the step Build your application, I can not understand it.I don't know how to build application.
Dear rongrong, wang
First please use OpenVino 2019R2 if you haven't done so already.
It's really simple.
1) copy one of the sample folders C:\Program Files (x86)\IntelSWTools\openvino_2019.2.242\inference_engine\samples into a new one and rename it to your project
2) Change the CMakeLists.txt file to reflect your target (project) name
3) run setupvars.bat (or *.sh) under bin
4) run build_samples_msvc.bat
Your new project will be built automatically. These instructions are for Windows but for Linux it will be similar.
Hope it helps,
A standalone project is a bit more complicated. I'd advise Open Source dldt for that. R2 should be added soon. I have given extensive instructions on how to build a standalone project to github issue 173
