Untar the File

If you received a tar file of LAPACK via the World Wide Web or anonymous ftp, enter the following two commands to untar the file:

gunzip -c lapack.tgz | tar xvf -

This will create a top-level directory called LAPACK, which requires approximately 34 Mbytes of disk space. The total space requirements including the object files and executables is approximately 100 Mbytes for all four data types.
