Pupanvr create project and management script (2)

Introduce

PUPANVR Is an open source embedded system NVR System , Designed to create a multi platform , Easy to use , The stability of the NVR System .

NVR Project description

Configuration of the project , Compilation is a reference Live555 Written in an open source way , It is mainly reflected in the root directory config Folder . But some scripts are from other chip manufacturers BSP You can take it in , For example, some scripts in Hisilicon security chip . Pay attention to the environment bash Used for debugging , Other environments have not been tested and used .

Purpose of the project

Implement different hardware in the same project , chip , Product function , Try to maintain a set of code .

Directory description

├── app Main application source code directory

├── config Product configuration catalog of different models

├── doc Document directory

├── hardware Some documents corresponding to different hardware

├── product Some documents corresponding to different products

└── tool Some tools will be packed when packaging , Put it here

Compile the way

1.  For different products , For example, the hardware is different or the business is different , stay config Write a configuration file in the directory ;
2.  Execute in the project directory  ./config/genMakefiles P30 (P30 Is the corresponding product configuration file name ,config Under the table of contents ), This step will generate buildout Catalog , And generate... In the directory Makefile;
3.  Execute directly under the project directory make app Compile application ;

　 stay buildout In the directory Makefile How is it generated , Please check out config Inside genMakefiles Related scripts .

In the past product development practice , Will face different hardware , Different product definitions , Function and other changes . In the project directory, a hardware The catalog of , Use this directory to isolate hardware related differences between different products .

stay product Directory , This directory can be used to isolate the differences between different products ,

also tool The subdirectories of the directory are used to distinguish and place files by chip , It is also convenient to distinguish different products , Different chip hardware , There may be some duplicate files .

app The directory stores the application engineering code , Use CMake To manage code scripts .

Product configuration example

Such as config In the directory P30 file , Content ：

# Define the cross compilation tool chain 
export PROJECT_CROSS_COMPILE=arm-hisiv600-linux

# Define the chip model 
export DEV_CHIP=hi3536c
export DEV_OS=LINUX
export DEV_SDK=hi3536c

# Define the product model 
export PRODUCT_SCRIPT=normal
# Product model 
export PRODUCT_MODEL=P30
export PRODUCT_BOARD=P30

export PRODUCT_MODEL_NUMBER=PUPANVR

export PROJECT_CFLAGS=""
export PROJECT_CPPFLAGS=""

Tool chains are defined respectively , Chip model , Product model , Hardware board end model , These macros will be imported into a header file through scripts , These macros can also be used in applications to distinguish different products ！
