c++ runtime libs are missing (or not accessible)


Dear All,

I am using RedHat5 and trying to install some programs. However, after trying to start the program, i got the following error message.("cara_1.8.4_linux" is the program I want to run)


[wen@wenpc ~/CARA]$ cara_1.8.4_linux
cara_1.8.4_linux: error while loading shared libraries: libstdc++.so.5: cannot o pen shared object file: No such file or directory


Does this mean the c++ runtime libs are missing or not accessible in the path? If do, how can I get it work?

I am not a linux person. So please help! I will greatly appreciate your help! Thank you very much!

That message usually means that the package is missing. You could try to install the libstdc++ package from repo if you can find one.

Red Hat 5 is horribly old release, you should change to a newer distro like Fedora 7 or CentOS.

Not that old if the OP means Red Hat Enterprise 5.

I assume that you need compat-libstdc++. Install it and do rpm -qpl to check whether it does provide libstdc++5.

Applications > System Settings > Add/Remove Applications.

Locate the package in question (as I said, probably compat-libstc++), select and click on apply.

This implies that you have working internet.

Thank you so muuch for helping me.

I did the following: System> Add/Remove Software, after I typed root passwaod, a "Package Manager" window appears, from "all packages", i found the following one:


libstdc++ - 4.1.1-52.el5.i386- GNU Standard C++ library


It seems that this package is already installed.

Is this package too old? Or should I do a software updte? Do I have to do the updata through RedHat.com?

Did you look for compat-libstdc++?

And no, the package that is installed is not too old, on the contrary - which doesn't mean you should remove it; I'm sure that it is needed by other applications.

libstc++ is not new software so doing an update won't help in this case.

Unfortunately, No.

libstdc++ is the only one I found.

I found a website:

http://rpm2html.osmirror.nl/libstdc++.so.5.html

do you think the one " libstdc++-3.2.2-5.i386 " will be applicable for my case? I downloaded it, but i don't know how to install. I am sorry to waste you so much time.

Weird. I should be there somehow. Try this command from a terminal

su -
(root password)
yum install libstdc++.so.5

Does that return anything?

If that doesn't help, you can install that file you found. But this is not the recommended way: the package is apparently more than a year old and it may at some point start producing issues with later packages.

If you do want to install it, place it on your desktop, then from a terminal:

cd /home/username/Desktop
rpm -ivh [name of the package]

If it installs, the downloaded file can be deleted (or saved somewhere else for later use).

Is it possible the path is not correctly set so that my program couldn't find the libstdc++?

OK, yum can't find it either - which is normal: it can only install packages listed in Add/Remove Applications. I assume that you could easily find the package if you registered with Red Hat but I don't know whether you intend to. If not, installing the package you already downloaded is the only option (other than installing a free version of Red Hat).

Here is the result after I tried to install the downloaded file:
