# 13

I don't know. And I don't know the NCL program.

But if it's only two users, it shouldn't be that time consuming to set up both.
Save a text backup for the first. And reuse the most of the settings for "number 2".

.

I have recently installed pixman-devel-0.18.4-1.el6_0.1.i686.rpm and
cairo-devel-1.8.8-3.1.el6.i686.rpm along with expat-2.0.1-11.el6_2.i686.rpm but still could not run the command ncargex cpex08 -clean.

[root@tu-localhost Downloads]# ncargex cpex08 -clean

NCAR Graphics Fortran Example <cpex08>

Copying cpex08.f

Copying cpexcc.f

Compiling and linking...
gfortran -fPIC -fno-second-underscore -fno-range-check -O -o cpex08

-lpng -lz -lbz2 -lpthread
/usr/bin/ld: cannot find -lexpat
collect2: ld returned 1 exit status

The compile and link failed.

hi dear
i have a problem same as frist problem of cent_sangeeta
but my system is linux fedore 16 arch i686
when i run NCL by typing:
[code] ng4ex gsun01n -clean

it reply:

ng4ex gsun01n -clean

NCAR Graphics NCL Example <gsun01n>

This example was set up to display the output to an

X11 window.

Copying gsun01n.ncl

Running NCL...

ncl: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory

ncl failed. “

there for i “locate libbz2.so.1.0” it reply : /lib/libbz2.so.1.0.6
and i set : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib in .bashrc file.
how i can solve following error due to libbz2.so.1.0
thanks

dear
it made me crazy
i use
yum install bzip2-lib
and
yum reinstall bzip2-lib
yum install bzip2-devel
but when type :ls /lib | grep libbz2
libbz2.so.1
libbz2.so.1.0.6
and again does not have libbz2.so.1.0

what can i do?
please help me

oh thanks
fortunatlly when i use cd /lib/ ; # ln -s libbz2.so.1.0.6 libbz2.so.1.0
libbz2.so.1.0 appear in /bin/
what does this command do?
please tell me , it makes me surprise.

# 23.

Delete the link in /bin/ .

And redo with :
1) su
2) cd /lib/
3) ln -s libbz2.so.1.0.6 libbz2.so.1.0

The command 'ln -s' creates a symlink. See $ man ln
http://linux.about.com/od/commands/l/blcmdl1_ln.htm

you mean that there was libbz2.so.1.0 in other place than /bin/ in my system and ln -s link that with libbz2.so.1.0.6 that located in /bin/ ?
there fore if libbz2.so.1.0 was not on my system this camman (ln -s) did not work?

# 25 .

There are not supposed to be any libraries at all in /bin/.
And neither will libraries be found, if located in /bin/.
/bin/ is not in the LD_LIBRARY_PATH, and shouldn't be.

-

you are on right. but i want to know that, if "ln -s .."create libbz2.so.1.0 in /bin/ or its task is just linking two libraries that were located previously? this quesion is because at first i did not have mentioned library in /bin/. and suddenly it was seen in home directory.

# 27 .

$ pwd : If your location is /home/name/, and you type ...
$ ln -s libbz2.so.1.0.6 libbz2.so.1.0
.. you can then test with ..
$ ls -l libbz2.so.1.0 : And get this reply ..
lrwxrwxrwx 1 name name <date> <time> libbz2.so.1.0 -> libbz2.so.1.0.6
.. and observe that libbz2.so.1.0 and libbz2.so.1.0.6
are blinking red to tell that it's not a valid link.
