OpenHarmony 4.0 源码编译hb 问题排查记录

OS:Ubuntu 22.04 x86_64

下载好Openharmony 4.0Beta2 的源码

$ pip3 install ohos-build
$ cd openharmony-4.0b2
$ hb set
Traceback (most recent call last):
  File "/home/loongson/.local/bin/hb", line 8, in 
    sys.exit(main())
  File "/home/loongson/.local/lib/python3.10/site-packages/hb/__main__.py", line 49, in main
    topdir = find_top()
  File "/home/loongson/.local/lib/python3.10/site-packages/hb/__main__.py", line 37, in find_top
    raise Exception("Please call hb utilities inside source root directory")
Exception: Please call hb utilities inside source root directory

从错信息看是找到某个目录，hb 是python写的，所以打算看看源码是找个目录出错了，根据出错信息直接看源码文件。

$ vim /home/loongson/.local/lib/python3.10/site-packages/hb/__main__.py

VERSION = "0.4.6"


def find_top():
    cur_dir = os.getcwd()
    while cur_dir != "/":
        hb_internal = os.path.join(cur_dir, 'build/lite/hb_internal')
        if os.path.exists(hb_internal):
            return cur_dir

        cur_dir = os.path.dirname(cur_dir)
    raise Exception("Please call hb utilities inside source root directory")

查看python 代码可知报错原因是没找到 build/lite/hb_internal，在OpenHamony 源码下确实没有发现有build/lite/hb_internal, 去OpenHarmony 源码仓发现build_lite这个仓库里面有，所以从这里下载一份到源码放到OpenHarmony 中去。

下载build_lite 源码, 从中复制hb_internal 到openharmony 的源码目录即可。

$ cd ../
$ git clone https://gitee.com/openharmony/build_lite
$ cd build_lite
$ cp -rf hb_internal ../openharmony-4.0b2/build/lite

$ cd ../openharmony-4.0b2
