libucb.s0.1: open failed...

Hi all.
I try to start an application, but libucb.so1 is missing.

After adding LD_LIBRARY_PATH

Starting OpenWindows in 2 seconds (type Control-C to interrupt)

XXXXXXX console login:

I changed the path /usr/ucblib:$LD_LIBRARY_PATH to /usr/lib:$LD_LIBRARY_PATH - the Openwindows run OK thereafter. :confused:

What is wrong? :mad:
Thanks.

So add both library paths to your LD_LIBRARY_PATH:

LD_LIBRARY_PATH=/usr/lib:/usr/ucblib:$LD_LIBRARY_PATH; export LD_LIBRARY_PATH

You would normally want /usr/dt/lib and /usr/openwin/lib in your LD_LIBRARY_PATH also.

vi .login

# Erasing LD_LIBRARY_PATH &

setenv LD_LIBRARY_PATH


# Important Paths set

setenv LD_LIBRARY_PATH     /usr/ucblib:$LD_LIBRARY_PATH

# Openwindows

setenv LD_LIBRARY_PATH    /usr/openwin/lib:$LD_LIBRARY_PATH

I tried many of variants.
But when I include the path /usr/ucblib exactly - OpenWindows doesn't run OK (e.g. start cmdtool window without csh % prompt etc.).

Setting LD_LIBRARY_PATH globally is a poor practice and leads to the issues you are experiencing. You need to either fix appl23 by recompiling it with providing the correct options or, if you have no access to the developement environment, set LD_LIBRARY_PATH just for that command:

env LD_LIBRARY_PATH=/usr/ucblib appl123
5

I do just the same Solaris 2.6 simply, but my box is running Solaris 8 02/04.

now, follow Jilliagre advice:

# setenv LD_LIBRARY_PATH
# setenv LD_LIBRARY_PATH   /usr/ucblib:$LD_LIBRARY_PATH appl23
setenv: Too many arguments
#
6

That wasn't my advice. Please read closer the command I suggested.

7

Am I missing something? Just create a symbolic link in /usr/lib for the missing libraries. I've done this before and it worked fine. I wouldn't mess with the LD_LIBRARY_PATH

8

I tried to create the symbolic link for the libucb.so.1 at /usr/lib.

# ln -s /usr/ucblib/libucb.so.1 /usr/lib/libucb.so.1
#
# cd /usr/lib
# ls -l
...
...
...
libucb.so.1 -> /usr/ucblib/libucb.so.1

But after adding in LD_LYBRARY_PATH - /usr/ucblib. OpenWindows run not OK.
see above.
Thanks.

You might have something else going on. If you left breadcrumbs, remove the links you created in /usr/lib and revert .login back to original. Concentrate on getting OpenWindows working then re-create the sym links.

Is the OpenWindows error the same as before?

10

The answer is to not change the LD_LIBRARY_PATH for your whole environment (never a good idea anyway) so don't put the change in ~/.login or ~/.profile but to write a wrapper scipt for you particular application, e.g.:

cat appl123.sh
#!/bin/ksh
LD_LIBRARY_PATH=/usr/ucblib:/usr/lib:/usr/openwin/lib:/usr/dt/lib
export LD_LIBRARY_PATH
appl123

That way only the environment for the application is changed.

chmod appl123.sh to 755 and then run appl123.sh instead of running appl123 directly.

HTH

K. I'm going to try that today.
I did that just the same Solaris 2.6 simply.
At 2.6 version that run without problem.
What is difference?

Thanks.

That's similar to what I suggested here two days ago but you apparently failed to copy/paste ... :

I tried following.

  1. I have two missing librarys ( libucb.so.1 and libXpm.so.4.0), see above please.
  2. By adding the path where is libucb.so.1, OpenWindows run not OK.
  3. I did the copy of libucb.so.1 from old mashine (sol 2.6)to new mashine/usr/ucblib. Old mashine ran appl23 some time.
  4. At /usr/lib I created the symbolic link to /usr/ucblib/libucb.so.1
  5. I did the copy of libXpm.so.4.0 from old mashine (sol 2.6) to new mashine /usr/lib.
  6. I did LD_LIBRARY_PATH=usr/openwin/lib:/usr/lib:
  7. I checked OpenWindows starting - OK
  8. appl23 was starting with other problems.

It's correctly?

14

In short, no.

I look for the SUNWxwrtl package therefore.
