Dear Masoud,<br><br>thanks very much for your help. I knew that I need to change the path but i did not know how so thanks for thr info. Unfortunately, my CSH shell does not support the EXPORT command so whenever I use it it outputs : Export: command not found. I do not have a /bin because this is running on my network account..I even tried before to use ln -s to copy stuff but permission was denied. is there any other command you are aware of for a csh/sh shell (other than export I mean)?<br><br>Thank you<br><br>ELie<br><br><hr id="stopSpelling">Date: Sat, 16 Apr 2011 14:11:00 +0430<br>From: masoudnahali@gmail.com<br>To: pw_forum@pwscf.org<br>Subject: Re: [Pw_forum] Fortan compiler cannot create executables<br><br>Dear Elie<br><br>Try "export PATH=$PATH:/path/to/your/directory/where/g95/installed" then update your database (updatedb command) and restart your computer. Also, you can copy g95 binary files from where you have installed the g95 to /bin.You should examine "g95" or "gfortran" commands in your linux console before trying to compile the QE. I hope it helps. <br>

Hello everyone,<br>
<br>
<br>
<br>
I am trying to re-install quantum espresso-4.3 on the University's LINUX interface (because of a recent crash and I lost most of my files).<br>
<br>
when I "sudo ./configure ", It is giving an error stating that :<br>
<br>
checking building system type... x86_64-unknown-linux-gnu<br>
<br>
checking architecture... x86_64<br>
<br>

checking for g95... no<br>
<br>
checking for f90... no<br>
<br>
checking for Fortran compiler default output... configure: error: Fortran compiler cannot create executables<br>
<br>
See `config.log' for more details.<br>
<br>
<br>
<br>
I have already installed g95. I really don't know why<br>
this error is coming.<br>
Please can anyone help.<br>
<br>
Thanks<br>
