Is GLIBCXX_3.4.9 required if I already set GLIBCXX_4.1.2?

Question

I am installing the latest version of MediainfoDLL on Fedora 8/9 64bits ( http://mediainfo.sourceforge.net/es/Download/Fedora ). I downloaded the libmediainfo-0.7.20 and libzen0-0.4.3 files.

When I tried installing libzen0, I get this output:

# rpm -i libzen0-0.4.3-1.x86_64.Fedora_9.rpm
warning: libzen0-0.4.3-1.x86_64.Fedora_9.rpm: Header V3 DSA signature: NOKEY, key ID dfb2ef23
error: Failed dependencies:
        libstdc++.so.6(GLIBCXX_3.4.9)(64bit) is needed by libzen0-0.4.3-3.1.x86_64

But the problem is that I already installed version of libstdC ++ 4.1.2:

# yum list libstdc++

libstdc++.x86_64                                                              4.1.2-33                                                               installed

How can I solve this problem?

Answer 1

Interestingly, I see an almost identical output from rpm -q --provides libstdc++. I suspect that the libzen0 RPM you are using has been compiled against the version of libstdC ++, which is not actually sent to your OS.

libzen0 ? ; RPM - . libzen0 RHEL 5.3?

64- , rpm: (Fedora 8) :

$ rpm -q --provides libstdc++
libstdc++.so.6
libstdc++.so.6(CXXABI_1.3)
libstdc++.so.6(CXXABI_1.3.1)
libstdc++.so.6(GLIBCXX_3.4)
libstdc++.so.6(GLIBCXX_3.4.1)
libstdc++.so.6(GLIBCXX_3.4.2)
libstdc++.so.6(GLIBCXX_3.4.3)
libstdc++.so.6(GLIBCXX_3.4.4)
libstdc++.so.6(GLIBCXX_3.4.5)
libstdc++.so.6(GLIBCXX_3.4.6)
libstdc++.so.6(GLIBCXX_3.4.7)

libstdc++ = 4.1.2-33
