<div>Yes, that is strange. The w2w file
should also be an "ELF 64-bit LSB executable".<br>
<br>
How about the w2w file in the SRC_w2w folder of the ~/WIEN2k.14/
directory, is it also gzip compressed data file?<div><div class="h5"><br>

<div>My system is a 64 bit redhat linux system. It's very
strange that the execution of "file w2w" showed "w2w: gzip
compressed data, from Unix, last modified: Sat Nov 20 04:32:01
2004." Actually I just compiled the latest version of wien2k
in this morning.</div>

<div>I also use the commad "file nn" in $WIENROOT and it gave me
the information about bit of nn.</div>

<div>That error usually happens if the w2w executable

then it is copied and ran on a 32 bit operating system

<br>
$ cd ~/WIEN2k.14/<br>
$ file w2w<br>
