OpenMPI, Emacs and libotf problems

[Amit Saha]

Hello all:

I am hoping it is OK to discuss this here. I came across this problem
when I was building a custom spin where the kickstart file installs
'openmpi' before 'emacs'.

When I start emacs, here is what I get:

$emacs
emacs: error while loading shared libraries: libotf.so.0: cannot open
shared object file: No such file or directory

So, this library is missing. However, this should have been installed
as its a dependency, right?

It can be seen that there are two providers listed for libotf.so.0.
Since 'openmpi' was already installed, so it didn't bother installing
'libotf'. I could simulate the scenario on a Fedora 15 installation:


Step1: Dependency listing
---------------------------------

$yum deplist emacs

 dependency: libotf.so.0
   provider: openmpi.i686 1.5-3.fc15
   provider: libotf.i686 0.9.12-2.fc15



To verify this scenario, the next step attempts to install emacs on a
machine without emacs, libotf and openmpi:

Step 2: Installing emacs
------------------------------

[gene at soma ~]$ sudo yum install emacs
Loaded plugins: langpacks, presto, refresh-packagekit
Setting up Install Process
Resolving Dependencies
--> Running transaction check
---> Package emacs.i686 1:23.2-19.fc15 will be installed
--> Processing Dependency: libotf.so.0 for package: 1:emacs-23.2-19.fc15.i686
--> Running transaction check
---> Package libotf.i686 0:0.9.12-2.fc15 will be installed
--> Finished Dependency Resolution

all good here.

(I don't proceed with the install)



Step 3: Installing openmpi
------------------------------
Next, I just install openmpi, which is listed as a provider for libotf.so.0:

[gene at soma ~]$ sudo yum install openmpi
Loaded plugins: langpacks, presto, refresh-packagekit

--> Running transaction check

Transaction Summary
===========================================================================================
Install       1 Package(s)

Total download size: 1.7 M
Installed size: 6.7 M


Install done.

Step 4: Installing Emacs after installing openmpi
---------------------------------------------------------------

[gene at soma ~]$ sudo yum install emacs
Loaded plugins: langpacks, presto, refresh-packagekit
Setting up Install Process
Resolving Dependencies
--> Running transaction check
---> Package emacs.i686 1:23.2-19.fc15 will be installed
--> Finished Dependency Resolution

                1/1

Installed:
  emacs.i686 1:23.2-19.fc15


It doesn;t list the dependeny anymore on libotf.so.0, since openmpi is
already installed.

And the result:

$emacs
emacs: error while loading shared libraries: libotf.so.0: cannot open
shared object file: No such file or directory


I also noted this discrepancy:

$sudo yum whatprovides libotf.so.0

Sorry for the long email, and I would be very happy to give any more
