The unixODBC package can be used to access databases through ODBC drivers. If you want to develop programs that will access data through ODBC, you need to install this package.
We can use yum or dnf to install unixODBC-devel on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install unixODBC-devel.
Install unixODBC-devel on CentOS 7 Using yum
Update yum database with yum using the following command.
sudo yum makecache
After updating yum database, We can install unixODBC-devel using yum by running the following command:
sudo yum -y install unixODBC-devel
Install unixODBC-devel on CentOS 7 Using dnf
If you don't have dnf installed you can install dnf first. Update yum database with dnf using the following command.
sudo dnf makecache
After updating yum database, We can install unixODBC-devel using dnf by running the following command:
sudo dnf -y install unixODBC-devel
How To Uninstall unixODBC-devel on CentOS 7
To uninstall only the unixODBC-devel package we can use the following command:
