Hello The developer has provided the repository at http://developer.huawei.com/ict/site-euleros/euleros/source/2.2/ I have downloaded some source rpm package from the provided repository, and can see the source file and headers. So I think after finding the location of the source file, this issue has been resolved. Thanks for help! _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
