== Package, install Skype 2.2.0.25 on CentOS 5 == CentOS 5 has its own **GCC Standard C++ Library** package, but it is relatively old: {{{ $ rpm -q --provides libstdc++-4.1.2-48.el5.i386 |grep GLIBC 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++.so.6(GLIBCXX_3.4.8) $ }}} Precompiled version of **Skype 2.2 Beta for Linux** requires a slightly newer version, {{{libstdc++.so.6(GLIBCXX_3.4.9)}}}. Will install the {{{libstdc++}}} package from **Fedora 10**, and make sure that it won't overwrite the one that came with the CentOS. 1. Download, install the GCC Standard C++ Library RPM from the Fedora 10 archive. {{{ # rpm -i --relocate /usr/lib=/usr/local/lib \ http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/10/Fedora/i386/os/Packages/libstdc++-4.3.2-7.i386.rpm # # rpm -ql libstdc++-4.3.2-7 /usr/local/lib/libstdc++.so.6 /usr/local/lib/libstdc++.so.6.0.10 # # ( cd /usr/local/lib ; ls -log libstdc++* ) lrwxrwxrwx 1 19 Apr 6 12:00 libstdc++.so.6 -> libstdc++.so.6.0.10 -rwxr-xr-x 1 954544 Nov 5 2008 libstdc++.so.6.0.10 # # whereis libstdc++.so.6 libstdc++.so: /usr/lib/libstdc++.so.6 /usr/local/lib/libstdc++.so.6 # }}} Now will download a few files, build and install the RPM. 2. Download statically compiled version of Skype (to avoid installation of **Qt 4**). {{{ # cd /usr/src/redhat/SOURCES # wget http://www.skype.com/go/getskype-linux-static/skype_static-2.2.0.25.tar.bz2 }}} 3.
