解决方案 #

1. 修复CentOS 8 YUM源 #

CentOS 8官方源已停止维护，需切换到归档源：

• 备份原有repo文件：

sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
sudo mv /etc/yum.repos.d/CentOS-AppStream.repo /etc/yum.repos.d/CentOS-AppStream.repo.bak

• 创建新的BaseOS和AppStream repo文件：

sudo tee /etc/yum.repos.d/CentOS-Base.repo <<EOF
[base]
name=CentOS-\$releasever - Base
baseurl=http://vault.centos.org/centos/\$releasever/BaseOS/\$basearch/os/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
EOF

sudo tee /etc/yum.repos.d/CentOS-AppStream.repo <<EOF
[appstream]
name=CentOS-\$releasever - AppStream
baseurl=http://vault.centos.org/centos/\$releasever/AppStream/\$basearch/os/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
EOF

• 清理并更新YUM缓存：

sudo yum clean all
sudo yum makecache

2. 安装编译所需依赖 #

修复源后，安装缺失的静态库和编译工具：

sudo yum install -y glibc-static libstdc++-static gcc gcc-c++

注：libpthread属于glibc-static包的一部分，无需单独安装libpthread-stubs。

3. 重新编译Go代码 #

再次执行编译命令：

CGO_ENABLED=1 go build
