Hi
I have i686 machine with centos 6.I am trying to install CISL's NCAR Command Language but problem arises due to libbz2.so.1.0
on giving command I get,

[root@tu-localhos Desktop]# ng4ex gsun01n

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.

so I tried to locate libbz2.so.1.0 and I got
[root@tu-localhost Desktop]# locate libbz2.so.1.0
/lib/libbz2.so.1.0.4


Sangeeta Maharjan

CentOS 6, bzip2-libs-1.0.5-*

Providing : /lib/libbz2.so.1 ,/lib/libbz2.so.1.0.4


You can just add the symlink "libbz2.so.1.0" : 1) cd lib/
2) su
3) ln -s libbz2.so.1.0.4 libbz2.so.1.0


.

Hi,

[root@tu-localhost Desktop]# ln -s /lib/libbz2.so.1.0.4 /lib/libbz2.so.1.0
ln: creating symbolic link `/lib/libbz2.so.1.0': File exists

Sorry, I didn't understand u well.do I need to download bzip2-libs-1.0.5-* and I have no idea about symlink so I try to find it


Thanks,
Sangeeta Maharjan

hi Knudfl,
I have Downloaded bzip2-libs-1.0.5-7.el6_0.i686.rpm and installed it but again my ncl didnot worke well so I removed it.To my surprise ,I get following messages

1st command->
[root@tu-localhost Downloads]# rpm -q bzip2-libs-1.0.5-7.el6_0.i686.rpm
package bzip2-libs-1.0.5-7.el6_0.i686.rpm is not installed

2nd command ->
[root@tu-localhost Downloads]# rpm -i bzip2-libs-1.0.5-7.el6_0.i686.rpm
package bzip2-libs-1.0.5-7.el6_0.i686 is already installed
3rd command->
[root@tu-localhost Downloads]# rpm -q bzip2-libs-1.0.5-7.el6_0.i686.rpm
package bzip2-libs-1.0.5-7.el6_0.i686.rpm is not installed

4th command ->
[root@tu-localhost Downloads]# rpm -i bzip2-libs-1.0.5-7.el6_0.i686.rpm
package bzip2-libs-1.0.5-7.el6_0.i686 is already installed

Thanks,
Sangeeta Maharjan

You are not supposed to install anything with # rpm -i

'rpm -i ' is for the exceptions, where you want two versions of a library.
And from the beginning you already had the correct package.
( The system command for package install is # rpm -Uvh )
For all package install, please use yum, if possible.


rpm -q bzip2-libs-1.0.5-7.el6_0.i686.rpm : Not a valid package name.
The package name can be verified with : $ rpm -qa | grep bzip2-libs


Post # 1 says you have : /lib/libbz2.so.1.0.4
Then it's simply # ln -s libbz2.so.1.0.4 libbz2.so.1.0

Knudlf,
It worked,
rpm -Uvh bzip2-libs-1.0.5-7.el6_0.i686.rpm

[root@tu-localhost Desktop]# locate libbz2.so.1.0
/lib/libbz2.so.1.0
/lib/libbz2.so.1.0.4

But another thing I didnt understand is while giving command ng4ex gsun01n it worked but didn't get [root@tu-localhost Desktop]# to go further

[root@tu-localhost Desktop]# ng4ex gsun01n

NCAR Graphics NCL Example <gsun01n>


This example was set up to display the output to an
X11 window.

Hi,I was bit hurry in last post.Actually it worked succesfully.

Finished running 'ncl < gsun01n'...

But again I encountered the problem in next command

User commands are not supposed to be run as root.

Your "user command" examples :
[root@tu-localhos Desktop]# ng4ex gsun01n
[root@tu-localhost Desktop]# locate libbz2.so.1.0
[root@tu-localhost Downloads]# rpm -q bzip2-libs-1.0.5-7.el6_0.i686.rpm
[root@tu-localhost Desktop]# locate libbz2.so.1.0
They can all be run as unprivileged user.
And : The most "GUI applications commands" will not work as root.

Please try the "ng4ex gsun01n command" as unprivileged user.

Root is for administrative tasks only. And using root is unsafe.

Hello Knudfl,
I have downloaded expat-devel-2.0.1-11.el6_2.i686.rpm.

Setting up Install Process
No package libexpat-devel available.
Error: Nothing to do

I will try to migrate in unprivileged user as soon as I set all the environment variables.
Thank you,
Sangeeta Maharjan.

It looks like you have no Internet connection ?

Or that something in the network setup in preventing the connection.

Actually I have downloaded this package in my home and tried to install in the lab.As we have very slow net connection.

Knudlf,
I have 2 unprivileged users. In order to run NCL in every unprivileged users, do I have to set all environment variables in all of them or do we have some method to manage it from the superuser(root).

Thank you,
Sangeeta Maharjan
