[openharmony] [rk2206] build openharmony compiler (2)

Above, ：

[OpenHarmony] Quickly build linux development environment +OpenHarmony Environmental Science ( One )

One 、 structure OpenHarmony compiler

1. download 【 Lingzhi electronics / Xiaoling sect -RK2206 Development board 】SDK
   from gitee download ： 【 Lingzhi electronics / Xiaoling sect -RK2206 Development board 】
   from csdn download ：lockzhiner-rk2206-openharmony3.0lts.zip

After downloading , Put it in linux Share Directory .
（1） stay D Disk creation prog Folder , And unzip it here .

If provided by this article linux, stay linux The input terminal ：cd /mnt/d/prog/lockzhiner-rk2206-openharmony3.0lts

If through other channels linux, Then share windos Catalog , Refer to appendix .
then cd Get into lockzhiner-rk2206-openharmony3.0lts Catalog .

（2） install hb Tools , The input terminal ：python3 -m pip install --user build/lite

（3） precompile , The input terminal ： ./build/prebuilts_download.sh

Compilation failure ：
① Complete dependencies are not installed , Please implement as above hm_install.sh, And run .
② shell Not changed to bash, Please follow the above operation .
③ python The version is not in 3.7-3.8 Inside , Build failed .
④ Not enough permissions , be chmod 777, Yes sdk The directory is weighted . Remember not to sudo function , Will report a mistake ！！！
⑤ Cannot create to “xx” The symbolic connection of : Operation not allowed . reason ： stay windos Shared folder perhaps Use windos Unzipped the file , The format is damaged . Please use linux Of unzip decompression sdk

（4） Set the environment variable , The input terminal ：source build/envsetup.sh

（5）hb For the first time, you need to add -root, The input terminal ： hb set -root $code_dir
（6） Select compile development board , The input terminal ： hb set
Use the direction key ↑↓, choice lockzhiner-rk2206.（ Ben SDK One by default , Press enter directly ）

Two 、 compile OpenHarmony project

（1） Clear old files , The input terminal ： hb clean
（2） compile , Suggestion plus -f Compile all , The input terminal ： hb build -f

Compilation failure ：

1. [OHOS ERROR] ./build.sh: 16: Syntax error: “(” unexpected
   reason ： Did not correctly handle shell Change it to bash
2. [OHOS ERROR] FAILED: obj/device/rockchip/rk2206/third_party/lwip/rk2206_lwip
   reason ： Complete dependencies are not installed , Please implement as above hm_install.sh, And run , then （1） Clear old files .
3. COPY Command not found ,python The version is not in 3.7-3.8 Inside , And there are errors in the composition of the environment

Shared directory reference ：virtualbox Set up shared directory

（1） The input terminal ：cd /mnt
（2） newly build Ubuntu Shared folders , The input terminal ：sudo mkdir /mnt/lockzhiner-rk2206-openharmony3.0lts
（3） Mount shared folder , The input terminal ：sudo mount -t vboxsf lockzhiner-rk2206-openharmony3.0lts /mnt/lockzhiner-rk2206-openharmony3.0lts/
Format ：sudo mount -t vboxsf Shared folder name ( See above ) To mount a directory
（4） Realize automatic mount after power on ,vim sudo gedit /etc/fstab

	 Input i, Enter edit mode , Add the following at the end . Press again esc, Exit edit mode . then shift+:, Enter command mode , Input wq, Press enter to save the changes .

lockzhiner-rk2206-openharmony3.0lts /mnt/lockzhiner-rk2206-openharmony3.0lts/ vboxsf defaults 0 0

Wrong situation ：

xxx The symbolic connection of : Operation not allowed
tar: Because of the last mistake , Will exit... In the last error state

This is because in the linux Used windos Caused by shared directory ！！！ Please put sdk From the shared directory to Linux Any path , Re decompress ！！！！
