(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
locate查看下有无libflexiblas64.so.3库：
locate libflexiblas64.so.3
没有，需要安装一下：
sudo dnf makecache
sudo dnf install epel-release -y
sudo dnf --enablerepo=crb install flexiblas-devel -y
sudo dnf install arpack -y
重新安装gdal 没有报错了。
sudo yum install gdal gdal-devel
