One of the most dreaded things that you can see while trying to run some application or trying to install an rpm package is a message saying that some required library is missing.
Generally this is not a big problem, because most often the library that you miss is packaged in a package named similarly to the library. Sometime however this is not the case… Suppose for example that you’re trying to install IBM JDK 5.0 on a Fedora 11 box. You’ll most likely get the following error message:
error: Failed dependencies: libstdc++.so.5 is needed by ibm-java2-i386-sdk-5.0-9.0.i386
and there is no package named libstdc++ that you can install, so how can you find out which package do you need?
The answer is simple:
$ yum provides libstdc++.so.5 Loaded plugins: fastestmirror, presto, refresh-packagekit compat-libstdc++-33-3.2.3-66.i586 : Compatibility standard C++ libraries Repo : fedora Matched from: Other : libstdc++.so.5
Pretty neat, eh?
