I don't have any experience with Lahey Fortran in many, many years. Could it be that their installation script is out of date and the required files are just in different locations? Perhaps /lib or /usr/lib?Quote:

sudo updatedb
On my box, it foundCode:locate libelf
/usr/lib/x86_64-linux-gnu/libelf-0.152.so
/usr/lib/x86_64-linux-gnu/libelf.so.1
One of those was a softlink to the other.
If that's the case you have a few options.
* fix the installation script to find the libraries already installed in different locations
* if all the required libs are in 1 directory, softlink that directory to /usr/lib64.
* if all the required libs are in multiple directories, softlink each into /usr/lib64.
* if all the required libs are in multiple directories, hardlink each file into /usr/lib64.
There are issues with soft-linking to either types, since any package update could remove them. You could use a hardlink to the exact library and that will keep it around, but that could cause other issues. A complete understanding of soft and hard links would help with your decision. http://linuxgazette.net/105/pitcher.html can help.
Softlinks are also known as symbolic links.
thanks for your reply..
But there are lot of files expected in /usr/lib64 folder.
actually it seems, this folder is needed for various other packages.
This /usr/lib64 was already present in earlier versions of ubuntu.
Is it possible to install in this 12.04 LTS version.
I got it Lahey FORTRAN installed under 12.04 LTS.Quote:

Create /usr/lib64, as this directory does not exist in 12.04.
Then link with sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib64.
Install Lahey
