I am using CentOS 64-bit (version 4.3) and am running into problems where 32-bit libraries are not installed. I have encountered problems with VMWare and needed to install the 32-bit libraries for X11 using the following command:
Now, I am having a problem with a proprietary server that was built as a 32-bit application as it can't find libstdc++.so.6. I tried the following command:
but I still get the same error when I try to run our application:
Does anyone know how to find out what yum package to install to get the 32-bit version of libstdc++?

Also, can anyone tell me how to find the package to install for a generic library that is missing? I am anticipating that this problem will come up again so I'd like to learn how to determine which package to install if possible.

I found the command searching through some other forums. The following command will install the 32-bit versions of libstdc++:
Can anybody provide any information on how to do this in the generic case? I.E. if I encounter another missing library?

I realise this is an ancient thread, but it could be useful to someone...

if you have a missing library - for example:

do;

then you can do;

and your missing library will be installed.

I'm going to dig up an old thread... I was installing Ventrilo server on Fedora 15 64 bit and realized i couldn't install it due to missing libraries. I seen the file that was missing and I found it exactly by using the whatprovides command. That was amazing.. Anyways much thanks!

I know this thread is old, but this saved me a lot of time. Thanks. I hope other people fun this useful.

The whatprovides should be more documented. I never heard of this until today. This might be yum's must kept secret.

Thanks,

I always use provides rather than whatprovides, because that is what I learned first and because I don't type very well. Maybe whatprovides is more intuitive, so easier to remember.

Unlike many important Linux tools, yum has a very beginner friendly man page. (what)provides is documented there both clearly and early (important for beginner friendly). In other tools some important beginner feature first mentioned on line 4000 of the man page "should be more documented". But that comment is unfair for whatprovides.

Nevertheless, for those too scared of man pages, I'm glad this thread exists.

For Debian based distributions, the corresponding apt functionality seems to be both not installed by default and harder to find in the documentation. I usually give up and instead go to
packages.ubuntu.com and scroll down to Search the contents of packages. Odds are the package which contains fileX in Ubuntu is the same as the package which contains fileX in some other Debian based distribution, so that is an easy place to get the answer, especially if you're looking for the answer at a moment in which you can't run apt (such as while I'm on the Windows computer I'm using right now).

For some major Red Hat based distribution, if someone happens to knows of a similar (public web accessible) substitute for yum provides that would be a nice URL to have posted in this thread.

Dag Weirs' site http(colon)(slash)(slash)dag.wieers.com/rpm/ is an excellent source for RPM's for older Red Hats. Click on the Installation and Configuration link and look up your release and arch. for most there is a choice of yum or apt repositories.
cheers.
