Hi, looks like a font issue. Do you have a /etc/xorg.conf file? and if so, do you specify the fonts in there? And do you have an $HOME/.xpdfrc file and what does it contain?

Hello my friend:
Thanks at first!
(1)What do you mean $HOME/.xpdfrc ?
My account looks like this: when I open the terminal, it is: [naishi@naishi~]$
when I type in pwd, it shows: /home/naishi
And based your meaning, could you tell me what the $HOME/.xpdfrc is? Or how can I go to the $HOME/.xpdfrc step by step? I am really confused about this point!
Based on my understanding, / is my root; /home/naishi is my current working subdirectory, is this right?
(2)can you tell me when I install a compiler(eg. ifort) whether I has to install this software in my root(ie. under /) or just need to create a subdirectory /home/naishi/intel_compiler and then install the ifort in this sub-directory? Please tell the step by step! Thank you indeed!
Thank you indeed!

Well, HOME is an environment variable containing the path to your home directory. You may see what it contains with echo(1)
Code:
echo $HOME
in a terminal. Now, issue,
Code:
cat $HOME/.xpdfrc
at the terminal and copy then paste the results in this thread. Also, issue
Code:
ls /etc/xorg.conf
grep -i font /etc/xorg.conf
and show me what you get.

As for your second question, you should really open another thread. You should also see whether the intel compiler is not available for your distribution. You could install it with your package manager.
But if you are the only user or the only person needing the compiler, you can install it in /home/naishi/intel_compiler and then, you either invoke it with ~/intel_compiler/ifort or you add $HOME/intel_compiler to the PATH variable,
Code:
PATH=$PATH:$HOME/intel_compiler
or you create an alias for it
Code:
alias ifort="$HOME/intel_compiler/ifort"

dear synss:
thank you very much! you are an expert indeed!
(1)i attach the results I did according to the commands i input:
[naishi@naishi ~]$ echo $HOME
/home/naishi
[naishi@naishi ~]$ cat $HOME/.xpdfrc
cat: /home/naishi/.xpdfrc: no this file or directory
[naishi@naishi ~]$ ls /etc/xorg.conf
ls: unable to visit /etc/xorg.conf :no this file or directory
[naishi@naishi ~]$ grep -i font /etc/xorg.conf
grep: /etc/xorg.conf: no this file or directory
(2)so, based on the info above, where can I get all the files (xorg.conf and ./xpdfrc). Addtionally, do I need to copy the necessary other files, how to get them?
(3)
ifort is the same as intel Fortran compiler, why need to create
/home/naishi/intel_compiler/ifort instead only of /home/naishi/intel_compiler; one more, does that mean if i install sth on the $PATH, then it needs root password or you are unable to do it? and everything installed in the $PATH can be shared by everyone?
thank you indeed! my friend!
i am looking forward to hearing from you soon!

Hi,

it is good that you have neither $HOME/.xpdfrc and /etc/xorg.conf, I was thinking they were cause of your problem. I think that the problem you have is that you are missing the helvetica font. Another thing is that xpdf is very strict with the fonts it requires and this is a bug, IMHO, but nothing you can do about. Could you tell me again if you have a file called /etc/xpdfrc and what it contains? And I think that if you run something like
Code:
LANG=C ls /etc/xpdfrc
etc., I mean by starting every line with LANG=C you should have the error messages in English, and you would not need to translate them. By the way, may I ask where you are from? I am just being curious. You don't have to answer if you don't want to.

Also, xpdf is OK but extremely basic, so if you have issue with it, you may want to try another one, maybe that would be the simplest fix for your problem. There is a bunch of Linux-only, free, pdf viewers, like kpdf (or okular if you use KDE 4), evince, gv, etc. You can also try Adobe Acrobat Reader or Foxit Reader, they both have Windows equivalents.

I personally use Acrobat and Evince.

mmm… This is something you should know. I do not want to sound RTFM, but at this point, you should really find a book or some internet pages about the basics of a Unix-like system. What do PATH and permissions mean, where to install softwares, and so on, is beyond a forum like this one. Moreover, google will most likely return 1000s of pages explaining you all that.

how to solve this problem step by step

Hi Synss,
Thank you very much!
I am in Quebec of Canada here, and I am doing numerical model simulation on UNIX system.And now I have to transfer to the Fedora 7 or 10 linux system on a Duo 2 core intel desk computer to run a big numerical model to do some simulation job there. So nice to know you too! Could you also tell me where you are and the status of you if you feel convenient tell, or no need to do it, okay, my friend!
Based on your good advice,
(1)I type in LANG=C ls /etc/xpdfrc in the command line, then message shows
ls: cannot access /etc/xpdfrc: No such file or directory

(2)could you be kind to tell me how to fix this problem step by step?
Thank you indeed! And learn from you!

Québec ? Je peux lire les messages d'erreur en français…

Anyway, there should be an xpdfrc file in /etc please look for it and show me its contents. Try
Code:
locate xpdfrc
and if it does not work,
Code:
find /etc -name xpdfrc
; one or the other will tell you where this file is and you can tell me what it contains with
Code:
cat
.

I cannot really see what the problem with the other fonts is, but I guess that xpdf does not understand
Quote:
"-*-screen-medium-r-normal--15-*-*-*-*-*-iso8859-1" to type FontStruct
because it should read
Quote:
"-*-screen-medium-r-normal-*-15-*-*-*-*-*-iso8859-1"
Did you try another pdf-reader?

Hi my friend,
Thanks again! You seem to know a lot about French. Where do you come from, my friend, I am also quite curious.
At first, I check the other computer on which xdiff works well there, in the /etc subdirectory, there are the followings(I copied everything here):

-------------------------------------------
So, there are also no .xpdfrc file there. I just wonder which one here take an effect as the same as the .xpdfrc does. Please help clarify this point.

However, in my this computer from which WHEN I access to the computer above the xdiff didn't work. From this one, I also copy all the things under /etc as follows:
------------------------------------------------------

So, there are also no .xpdfrc here. So, why?
And how to fix this problem?

Hope to get good advice from you asap!
Thank you again!

And did you update your system, recently? When? Maybe the problem has been resolved, already.

You could try to set up an xpdfrc file man(5) xpdfrc, by the end, there is a sample file, take what you need from it. I do not know what fonts you have installed on your system and where they are so I cannot really help. See if helvetica is missing.

May as well look at: http://linux.die.net/man/5/xpdfrc

The system configuration file will not be a dot-file (xpdfrc, not .xpdfrc) and if it were a dot-file, it would not show with a simple ls, please find some introductory book on Linux, be it online or at your local library.

I am French, although I leave in Germany.
