OpenHarmony 4.0 Release 编译异常处理

一、环境配置

���译环境：Ubuntu 20.04

（）

OpenHarmony 软件版本：4.0 Release

设备平台：rk3568

（）

二、下拉代码

参考官网步骤：

OpenHarmony 4.0 Release 源码获取

repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-4.0-Release --no-repo-verifyrepo sync -crepo forall -c 'git lfs pull'

三、编译代码

参考官网构建步骤：

v4.0 Release 编译构建

 bash build/prebuilts_download.sh./build.sh --product-name rk3568 --ccache

如果上述步骤一切顺利，编译通过，build log如下：

...Please modify according to README.md[OHOS INFO] rk3568 build success[OHOS INFO] Cost time:  0:58:44=====build  successful=====2023-11-08 14:48:55++++++++++++++++++++++++++++++++++++++++

四、下拉及编译中遇到的问题

4.1、repo: error: unable to resolve “fork_flow”

下拉代码执行报错

$ repo init -u https://gitee.com/openharmony/manifest -b master --no-repo-verifyDownloading Repo source from https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/remote: Enumerating objects: 4885, done.remote: Counting objects: 100% (4885/4885), done.remote: Compressing objects: 100% (2425/2425), done.remote: Total 8626 (delta 4312), reused 2460 (delta 2460), pack-reused 3741Receiving objects: 100% (8626/8626), 4.16 MiB | 9.25 MiB/s, done.Resolving deltas: 100% (5577/5577), done.repo: warning: verification of repo code has been disabled;repo will not be able to verify the integrity of itself.repo: error: unable to resolve "fork_flow"fatal: cloning the git-repo repository failed, will remove '.repo/repo'

unable to resolve “fork_flow”" 表明repo工具无法解析名为 “fork_flow”,实际上fork_flow是repo仓库的一个分支

repo源码：开源中国/repo

解决方案：修改REPO_REV默认值为stable

$ which repo#查看repo安装路径/home/xxx/bin/repo$ sudo vim /home/xxx/bin/repo #REPO_REV = 'fork_flow' 改为 REPO_REV = 'stable' 

4.2 ERROR: HTTP error 404 while getting http://repo.huaweicloud.com/repository/pypi/…

执行bash build/prebuilts_download.sh后出现如下报错

$ bash build/prebuilts_download.sh Defaulting to user installation because normal site-packages is not writeableLooking in indexes: http://repo.huaweicloud.com/repository/pypi/simpleCollecting rich  Obtaining dependency information for rich from http://repo.huaweicloud.com/repository/pypi/packages/8d/5f/21a93b2ec205f4b79853ff6e838e3c99064d5dbe85ec6b05967506f14af0/rich-13.5.2-py3-none-any.whl.metadata  ERROR: HTTP error 404 while getting http://repo.huaweicloud.com/repository/pypi/packages/8d/5f/21a93b2ec205f4b79853ff6e838e3c99064d5dbe85ec6b05967506f14af0/rich-13.5.2-py3-none-any.whl.metadataERROR: 404 Client Error: Not Found for url: http://repo.huaweicloud.com/repository/pypi/packages/8d/5f/21a93b2ec205f4b79853ff6e838e3c99064d5dbe85ec6b05967506f14af0/rich-13.5.2-py3-none-any.whl.metadataprebuilts_download start...

无效url:http://repo.huaweicloud.com/repository/pypi/packages/…

解决方案：

使用其他国内（清华）镜像源替换华为的pypi源,修改如下：

# build/prebuilts_download.sh-    pypi_url='http://repo.huaweicloud.com/repository/pypi/simple'+    pypi_url='https://pypi.tuna.tsinghua.edu.cn/simple'

4.3 一直卡在start npm install, please wait.

执行bash build/prebuilts_download.sh后一直卡在start npm install, please wait.

分析prebuilts_download.sh代码发现是npm源的问题，于是替换npm默认url

解决方案：

使用国内（淘宝）镜像源替换华为npm源，修改如下：

# build/prebuilts_download.py-    parser.add_argument('--npm-registry', default='https://repo.huaweicloud.com/repository/npm/',+    parser.add_argument('--npm-registry', default='https://registry.npm.taobao.org/',

先从出现ERROR开始处分析一遍报错log，若无明显代码报错，可尝试：

sudo ./build.sh -p rk3568

sudo 命令在共用编译服务器慎用，以免影响其他人的编译环境。

若使用sudo编译通过，则说明与编译环境有关，可从以下几个方面处理：

• 重新配置编译
• 重装编译系统
• 使用docker编辑编译，可参考博文：Docker 编译OpenHarmony 4.0 release
