Can't install newer Fortran compilier

[dxf_dxf_dxf]

Hi,
I have installedintel_composer_xe_2011_sp1.7.256 on our cluster, and I don't have access to root so I install as a nonroot user. However I find my vasp does not work well, and I think maybe I should choose a newer compiler, so I downloadedintel_composer_xe_2011_sp1.9.293 and try to install it.

I just "rm INSTALLPATH/intel/* -rf" so as to remove older intel compiler, however when I want to install the newer compiler, the system tells me "" so I have no intel compiler now.

and I found in step 4 "

You are now ready to begin installation. You can use all default installation

settings by simply choosing the "Start installation Now" option or you can

customize these settings by selecting any of the change options given below

first. You can view a summary of the settings by selecting

"Show pre-install summary".

1. Start installation Now

2. Change install directory [

/publicfs/dyb/data/userdata/dingxf/intel/composer_xe_2011_sp1.7.256/composer_xe_

2011_sp1.9.293 ]

3. Change components to install [ All ]

4. Show pre-install summary

h. Help

b. Back to the previous menu

q. Quit

--------------------------------------------------------------------------------

Please type a selection or press "Enter" to accept default choice [1]: 2

The install directory path cannot be changed because at least one software

product component was detected as having already been installed on the system.

Press "Enter" key to continue: "

how can I remove the older one completely? thanks!

Did you select the non-root install? If not, you are being stopped from doing something which may conflict with a root install on your system.
If you removed an installation that way when it was registered by rpm, you will need to find the rpm entries e.g.
rpm -qa | grep intel
and run rpm -e on the entries corresponding to what you deleted. If you don't have privilege to do this, you'll need sysadmin help.
You should have run the uninstall script in your compiler installation before removing it.

You seem to have got into the kind of fix I'm in on Windows.

I don't have root priviliage, so the older version is installed via non-root method; and "rpm -qa | grep intel" returns blank line.
I have installed ifort on another machine so as to get the uninstall.sh script; I run it on my computer but only get "installed by another user" and failed. I modified the script to ignore this err, but got "cannot find any installation" err, and failed again.
Now the older one is deleted, and the new one cannot be installed.

Step no: 5 of 6 | Installation

--------------------------------------------------------------------------------

Each component will be installed individually. If you cancel the installation,

components that have been completely installed will remain on your system. This

installation may take several minutes, depending on your system and the options

you selected.

The older one is installed on
${WORKHOME}/intel/composer_xe_2011_sp1.7.256
I rm -f the whole intel menu
And after I installed the newer one (and get "failed"), I found
${WORKHOME}/intel/composer_xe_2011_sp1.7.256/composer_xe_2011_sp1.9.293
was created,
and I found only two under it:

2 days have passed. Does anyone know how to resolve this problem?
I cannot use intel compiler now.

[dxf_dxf_dxf]

I find http://software.intel.com/en-us/forums/showthread.php?t=69116 and rm -rf ~/intel, and the problem is solved.
BTW, I install intel to $WORKHOME/intel/ rather than $HOME/intel.
