If you are getting the error
thunderbird-bin: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by libxul.so)You have come to one of the correct places. This is a continuation of the FIreFox 4 install. Again, I did not come up with this on my own! I just want to spread the word as much as possible that one very enlightened fellow referenced as "rkl" at forums.mozillazine.org has made it possible for the rest of us to hit the "easy button" and got FireFox 4.0 working on CentOS 5.x (CentOS 5.6 at this time). HERE is the original link that I lucked upon while trying to google it on my own.
This is my mostly plagiarized summary based on the original FF4 information for the link above. My testing was specifically done on CentOS 5.6 32bit desktop install:
1. Unpack the Thunderbird thunderbird-5.0.tar.bz2 somewhere (e.g. /opt/thunderbird5). A quick way to get the tar file is from the mozilla Thunderbird EN download link.
2. Download this 32-bit Fedora 9 libstdc++ RPM and unpack it with this command:
rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i --make-directories
3. Move the unpacked shared library into /opt/thunderbird5:
mv usr/lib/libstdc* /opt/thunderbird5/
Note: It's "usr/lib/libstdc*" above (i.e. the unpacked tree from the RPM, not the system /usr/lib tree) - do NOT put a leading slash there!
4. Run Thunderbird 5 with:
I will say that TB5 is an *major* improvement from Thunderbird 3.x. So far there are less mailbox issues than with previous versions.
