Hi Communityer Regarding the StarlingX Build Guide： When we built the latest version of StarlingX, we found some build guide issues and raised them here.： Guide Path：https://docs.starlingx.io/developer_resources/build_guide.html ★Issues (1). Paragraph: Build the CentOS mirror repository cd $HOME/tools/centos-mirror-tools/ docker run -it --volume $(pwd):/localdisk local/$USER-stx-builder:7.4 bash cd localdisk && bash download_mirror.sh The above steps are no longer applicable to the current StarlingX Master environment construction. At the same time, this step will directly lead to the following download error. [root@5fc5c5f5f610 /]# cd localdisk && bash download_mirror.sh download_mirror.sh: line 8: /localdisk/../toCOPY/lst_utils.sh: No such file or directory download_mirror.sh: line 232: merge_lst: command not found download_mirror.sh: line 233: merge_lst: command not found download_mirror.sh: line 234: merge_lst: command not found download_mirror.sh: line 235: merge_lst: command not found download_mirror.sh: line 236: merge_lst: command not found -------------------------------------------------------------- WARNING: this script HAS TO access internet (http/https/ftp), so please make sure your network working properly!! step #0: Configuring yum repos ... download_mirror.sh: line 345: [: !=: unary operator expected As the result, the compilation and construction of StarlingX could not be implemented. Temporary countermeasure: In order for download_mirror.sh to run normally, we have adopted the following methods to deal with it, Methods as below: cd $HOME/tools bash tb.sh run bash tb.sh exec -------------------------- [zs@af1b85270819 /]$ cd $MY_REPO_ROOT_DIR [zs@af1b85270819 starlingx]$ cd stx-tools/centos-mirror-tools/ [zs@af1b85270819 centos-mirror-tools]$sudo MY_REPO=/localdisk/designer/zs/starlingx/cgcs-root ./download_mirror.sh Although this solution can currently solve the download_mirror.sh Error problem temporarily. However,We hope the community can provide better solutions to share, Thank you! -------------- From: Neusoft - Shuai --------------------------------------------------------------------------------------------------- Confidentiality Notice: The information contained in this e-mail and any accompanying attachment(s) is intended only for the use of the intended recipient and may be confidential and/or privileged of Neusoft Corporation, its subsidiaries and/or its affiliates.
