Intel fortran compiler 10.0.023 under Ubuntu Gutsy

I had the problem that I need to use the Intel fortran compiler under Ubuntu Gutsy. This was a bit harder to setup than I initially expected, since Ubuntu 7.10 is not supported by Intel. After fiddling around for a while I found a way to make it work and I would like share the solution with anybody else that is interested so you wont need waste as much times as I.

Before the installation
First of all I need the installation files from Intel, so I went to the web page
http://www.intel.com/cd/software/products/asmo-na/eng/282048.htm
and chose the “Free Non-Commercial Download”. After registering I received an email with the a license file ending with .lic. I saved the license to /home/tjansson/ as I will need it later.

Some other packages are need to complete the installation of the compiler:

root@dirac:~#aptitude install alien g++-multilib libstdc++5 build-essential

Installation
Since I could not get the default installation to work I ended up finding these pages which really helped me and my mini howto is based on those.
http://www.intel.com/support/performancetools/sb/CS-025939.htm
http://ubuntuforums.org/showthread.php?p=3621092

For some strange reason Ubuntu uses dash and not bash as the shell /bin/sh. This creates problems since dash does not have the same functions as bash which is needed by the Intel programs (and programs others too). So I remove the link from sh to dash and replace it with a link to bash instead.

root@dirac:~#ls -l /bin/sh
lrwxrwxrwx 1 root root 9 2007-10-31 16:57 /bin/sh -> /bin/dash
root@dirac:~#rm /bin/sh
root@dirac:~#ln -s /bin/bash /bin/sh

After this I unpacked the tar ball I downloaded earlier and created a .deb file from the .rpm files included in the tar ball and install the .deb file.

tjansson@dirac:~$tar xvzf l_fc_p_10.0.023_ia32.tar.gz
tjansson@dirac:~$cd l_fc_p_10.0.023_ia32/data/
 
tjansson@dirac:~/l_fc_p_10.0.023_ia32/data$su
Password:
root@dirac:/home/tjansson/l_fc_p_10.0.023_ia32/data# alien -cv intel-ifort100023-10.0.023-1.i386.rpm
root@dirac:/home/tjansson/l_fc_p_10.0.023_ia32/data# dpkg -i intel-ifort100023_10.0.023-2_i386.deb

Even though the program is now installed all the files refer to <INSTALLDIR> and not /opt/intel/fc/10.0.023/ as it should. So I use sed to replace all occurences of <INSTALLDIR> with /opt/intel/fc/10.0.023/ . This has to be done at least with ifort and ifortvars.sh. I ran the following command as root

sed -i 's/&lt;INSTALLDIR&gt;/\/opt\/intel\/fc\/10.0.023/g' /opt/intel/fc/10.0.023/bin/ifortvars.sh

of course this could be done with any editor but I think this is faster. Sorry for the bade code display – WordPress is messing with my style.

Next I moved the license file (.lic) to the license folder created by the Intel compiler installer:

root@bohr:~# mv /home/tjansson/*.lic /opt/intel/fc/10.0.023/licenses/

The final step was to add a line in the file /home/tjansson/.bashrc to make the shell inherit some intel variables:

source /opt/intel/fc/10.0.023/bin/ifortvars.sh

Testing the installation
The final exercise is to test whether or not the compiler works. So I made a simple program and saved it as helloworld.f90

PROGRAM HelloWorld
   PRINT *, "Hello World"
END PROGRAM HelloWorld

Then I tried to compile the code to see if it worked

tjansson@dirac:~$ifort helloworld.f90
tjansson@dirac:~$./a.out
 Hello World

And finally it did 😀

  1. Josh says:

    Thanks for the tips my compiler works now as well.

    Just to let you know there is a typo in your rpm conversion command you have
    ” alien -cv” twice

  2. Glad to know it helped you. 😀 And thx for the heads up on the typo – it should be fixed now.

  3. ping says:

    Thanks for you guide, the intel fortran compiler 10.1.008 works on my ubuntu gusty too.
    But I have one more question,I find ‘ifortvars.sh’ also has some , do we need to replace them with the actual path /opt/intel/fc/10.*.***/bin ?

  4. Christian says:

    Thank you so much for this HowTo – what would I do without ifort :o)?

  5. Rui Caldeira says:

    Thanks for this excellent help!

    Everything worked fine during your suggested installation procedure, except that ifort would not start before I added the following line:

    alias ifort=’/opt/intel/fc/10.1.008/bin/./ifort’

    to my ‘.bashrc’ any idea why this difference? I have installed ifort -v 10.1.008

  6. Debabrata says:

    Thanks for your how-to.I am running Ubuntu 7.10. I followed all your steps. But I finnally could not fish with success!!! While try to compile ‘hello world’ code. It shows the error:

    $ ifort fortrantest.f95
    /opt/intel/fc/10.1.008/bin/ifort: line 40: /opt/intel/fc/10.0.023/bin/ifortbin: No such file or directory
    /opt/intel/fc/10.1.008/bin/ifort: line 40: exec: /opt/intel/fc/10.0.023/bin/ifortbin: cannot execute: No such file or directory

    NB: like the last post by Rui Caldeira, ifort did not start before I added the following line:

    alias ifort=’/opt/intel/fc/10.1.008/bin/./ifort’

    to my ‘.bashrc

    ANY idea please!!!

  7. Rul Calderia and Debabrata: I think the reason for this is that the line in in your .bashrc file isn’t working:

    
    source /opt/intel/fc/10.0.023/bin/ifortvars.sh
    

    In this files you $PATH environment variable is altered to include the path of ifort. If it is done correctly the file should look something like this:

    
    if [ -z "${PATH}" ]
    then
        PATH="/opt/intel/fc/10.0.023/bin"; export PATH
    else
        PATH="/opt/intel/fc/10.0.023/bin:${PATH}"; export PATH
    fi
    

    But if ifortvars.sh hasn’t been changed by the sed command I presented you should open the ifortvars.sh and replace all occurrences of
    <INSTALLDIR>
    with
    /opt/intel/fc/10.0.023/

    Update: The reason that it failed was the the sed command attacked
    /opt/intel/fc/10.0.023/bin/ifort
    and not
    /opt/intel/fc/10.0.023/bin/ifortvars.sh
    as it should. Sorry for the typo. 🙁

  8. OK. thanks for your reply. Now I followed your last tips. I just opened the /opt/intel/fc/10.1.008/bin/ifortvars.sh and replaced the
    with
    /opt/intel/fc/10.1.008/

    and so now its working perfectly.

    Thanks. Good luck.

  9. leonardo says:

    thank you for your excellent how-to!
    I’ve one more question.. I cannot find the file *.lic, and it seems that the installation program did not create it…

    any suggestions?

    thanx a lot

  10. guillaume says:

    thanks for your help !

    I have the same problem as Leonardo, no licence file generated by the install.sh script (because it crashes before with bash and dash…)
    can someone provide the license file code please ? does it contain only the serial number ? thanks !

    bye

  11. Leonardo & Guilaume: As I wrote in the beginning of the article – I received the .lic file attached to the mail from Intel. So you register on their site and and you should receive one. 😀

  12. Irian says:

    Thanks a lot it works!

  13. Renato says:

    I’ve followed all the tips but when I try to compile I receive this message:

    renato@snoopy:~/latex/programas/utf-8$ ifort galerkin.for
    fortcom: Info: The input stream is empty
    /opt/intel/fc/10.1.008/lib/for_main.o: In function `main’:

    What’s wrong?

    Thanks a lot.

  14. Georg Madsen says:

    Fremragende. Tak. Det virkede også for icc.
    Jeg installerede 10.1.008 versionerne og her skal man også bruge dit sed hack på selve scriptet:
    —————————————————————
    sed -i ‘s//\/opt\/intel\/cc\/10.1.008/g’ /opt/intel/cc/10.1.008/bin/icc
    —————————————————————
    og ligesådan for ifort

  15. Peter Smale says:

    Thanks! This all worked exactly as you said (I used 10.0.023 too). I’m very happy.

  16. Doug McKee says:

    I don’t know German, but I think I agree with Georg above– these instructions work great (with slight mods) for installing the Intel C compiler (icc) too!

    Thanks!

  17. khaled says:

    HI tjansson
    thanks for u r help…I’m new in linux…..I’ve followed all the tips…
    i’m using the 10.1.008 version…it works but I still have a problem.

    root@Nada:/home/khaled# ifort somme.for
    bash: ifort: command not found
    root@Nada:/home/khaled# alias ifort=’/opt/intel/fc/10.1.008/bin/./ifort’
    root@Nada:/home/khaled# alias
    alias ls=’ls –color=auto’
    alias ifort=’’/opt/intel/fc/10.1.008/bin/./ifort’’
    root@Nada:/home/khaled# ifort somme.for
    bash: ifort: command not found
    root@Nada:/home/khaled# /opt/intel/fc/10.1.008/bin/./ifort somme.for
    root@Nada:/home/khaled#

  18. HI khaled:

    If the line in your .bashrc really worked
    source /opt/intel/fc/10.0.023/bin/ifortvars.sh
    it shouldn’t be necessary but if you would like to do the alias instead there is a strange dot in your path. The correct path in your case would be something like:
    alias ifort=’/opt/intel/fc/10.1.008/bin/ifort’

    I hope this helps 🙂

  19. khaled says:

    Thanks Jansson,
    first ,wish u a happy new year..
    ..Now everything works well….
    I just want to notice that, what i wrote about the alias is due to the “kommentar ” of Debabrata siger:
    24. november 2007 kl. 19:08
    NB: like the last post by Rui Caldeira, ifort did not start before I added the following line:

    alias ifort=’/opt/intel/fc/10.1.008/bin/./ifort’

    ..I still need an unser about this :
    I’ve 2 prgms : 1) somme.for and 2) test.for
    when i compile them with ifort..it always give me [ a.out ]…… what command should i type to have for example [ somme.out ]and [ test.out ]

    thank you again for u r help

  20. Hi Khaled

    When you compille just use the -o option:

    ifort test.for -o test.out

    Glad I could help. 🙂
    The manual is online if you need more help look into:

    Thanks a lot my friend really appreciate the help…

  27. Mario says:

    I have a little problem with this. It works all right, but when i exit the terminal it forget the commande ifort…
    I have to run source /opt/intel/fc/10.1.018/bin/ifortvars.sh again, them ifort works on this terminal…
    I think is not correct to run source every time…
    I couldn’t find the problem, have you got any idea?
    thanks from Argentina
    Mario

  28. Mario says:

    Isolved the problem adding the line:

    excellent guide . i was struggling to install until i got to ur web page. keep up the good work

  30. Joao says:

    I followed your instructions. They are a good help.

    HOWEVER when I try to compile a simple “hello world” program with the instruction “ifort hello.F90” i get this error:

    ld: /opt/intel/fce/10.1.018/lib/for_main.o: No such file: No such file or directory

    This is strange because THERE IS a file called for_main.o in that directory!

    Note that my version is 10.1.018

    Can somebody help???

    Thanks

    J

  31. joao says:

    ok… I managed to sort the problem by simply running intel script. It seems to work fine!!!

    J

  32. Yes it sounded like a LD_LIBRARY_PATH problem. 🙂 Glad you got it fixed.

  33. Ben Pietras says:

    Hi, for hardy after downloading the l_fc_p_10.1.018.tar.gz, gunzip, ./install.sh and putting in my

    N3KT-LJZGNDL3 verification code all I needed to do was add

    if [ -f /opt/intel/fc/10.1.018/bin/ifortvars.sh ]; then
    . /opt/intel/fc/10.1.018/bin/ifortvars.sh
    fi

    to ~/.bashrc

  34. kevinchkin says:

    Dude, Thanks a lot man. It was annoying me since forever and then your article came up like a savior.

    I just had to run this command for both files i.e. ifort and ifortvars.sh
    sed -i ‘s//\/opt\/intel\/fc\/10.0.023/g’ /opt/intel/fc/10.0.023/bin/ifortvars.sh

    After that it worked like a charm.

    Thanks once again bro.

  35. mohammad says:

    Dear Users,

    Actually I want to install Ifort and KML on RedHat 4 Linux, but first of all I do not have this software (any body can help me to find a freely version ?) I installed ifort evaluation but I want to uninstall it , can any one help me to do that ? because I can not find its name, for example I am using of $rpm -e , but I do not know which name should I mention to uninstall, because when i write intell fortran or ifront , it says this file can not find .

  37. Hi Sork

    I has been a while since I have used Intel Compilers ( I wrote this in 2007 and I am not using them at my work, so I a bit rusty). It definitely looks like that you have a PATH problem:

    /bin/bash: ifort: orden no encontrada

    Which means that bash does understand the command “ifort” – which is because this does point to any executable. To test if ifort really works try to use the “which” command. Here I try to find where xterm points to and it shows me the path to the executable

    tjansson@euler:~$which xterm
    /usr/bin/xterm

    If I tried to do the same to ifort, which I do not have installed I would get this:

    tjansson@euler:~$which ifort
    tjansson@euler:~$

    What I would do was to open a new terminal and try to execute the

    source /opt/intel/composerxe-2011.2.137/bin/ifortvars.sh intel64

    command. If this gives an error or does not make ifort a part of you path – you should open up this script and try out why it fails.

    Finally also check that the ifort binary actually is in the folders:
    /opt/intel/bin
    /opt/intel/composerxe-2011.2.137/bin/intel64

    Kind regards
    Thomas Jansson

    Can anyone tell me how to uninstall ifort from linux OS. I am using fedora tn version of linux OS.

  39. fahrettin says:

    it’s been years. 😀
    But you may help me, I have followed the instructions that u gave for installation of ifort (10.0.023 is my version) on ubuntu 12.04. My problem is *.lic file. I registered intel and they sent me only a serial number in format NTJL-********. There was no attachment.
    Any help would be greatly appreciated.

  40. Hi Fahrettin

    I am sure that the procedure on Intel side has changed over the seven years since I wrote this piece and I have not been using the compiler for last many years, so I cannot help you unfortunately.

    All the best
    Thomas
