rk3568 OpenHarmony 3.2 Release 编译(踩坑记)-从镜像站点获取源码包编译失败_openharmony3.2生成镜像

系统使用LinuxMint-20.3

源码从镜像站点获取：
全量代码（标准、轻量和小型系统） 3.2 Release 21.8 GB

不是通过repo方式获取的，下载后源码压缩包名称code-v3.2-Release.tar.gz
解压后路径root/data/harmony/release_code/2023-040-09/OpenHarmony-v3.2-Release/OpenHarmony，
这个是压缩包里包含的路径，不是我加上去的。

解压源码后在源码目录执行：
bash build/prebuilts_download.sh

执行编译：
./build.sh --product-name rk3568 --ccache

出现如下错误：

[OHOS ERROR] ../../foundation/multimedia/histreamer/engine/plugin/core/plugin_register.cpp:314:5: error: use of undeclared identifier 'RegisterPluginStatic'
[OHOS ERROR]     RegisterPluginStatic(std::make_shared<RegisterImpl>(registerData));

[OHOS ERROR] ../../foundation/multimedia/histreamer/engine/plugin/core/plugin_register.cpp:357:5: error: use of undeclared identifier 'UnregisterPluginStatic'

经分析是因为’RegisterPluginStatic’和’UnregisterPluginStatic’没有定义。
查看foundation/multimedia/histreamer/engine/plugin/core/plugin_register.cpp源码，包含头文件all_plugin_static.h，但是该头文件没有生成，
all_plugin_static.h头文件是python脚本foundation/multimedia/histreamer/engine/plugin/plugins/plugin_config.py生成的，但不知道什么原因，该
脚本好像没有执行，导致头文件没有生成。

自己手动生成all_plugin_static.h文件，并放到foundation/multimedia/histreamer/engine/plugin/core/目录下，继续编译，
出现如下错误：

实在无解，怀疑是源码压缩包解压后的路径不是打包路径，怀疑要完整的按照压缩包解压的路径存放源码，即源码路径/root/data/harmony/release_code/2023-040-09/OpenHarmony-v3.2-Release/OpenHarmony/
由于编译时间比较长，以上疑点就没有验证了，且需要/root目录，这个估计要root权限。

于是使用repo方式下载源码，执行：
repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-3.2-Release --no-repo-verify
repo sync -c
repo forall -c ‘git lfs pull’

编译源码
bash build/prebuilts_download.sh
./build.sh --product-name rk3568 --ccache

编译成功，编译过程丝般顺滑，并没有出现以上错误。

所以为了避免踩坑，建议不要用从镜像站点获取源码包的方式来下载源码，希望openharmony的工程师验证下。
