The usual trick of tricking the executable by creating a symlink named with the earlier version doesn't work; firefox-bin then complains that it can't find the symbols GLIBCPP_3.2 and CXXABI_1.2 in what it thinks to be so.5, but is of course so.6. Reproducible: Always Steps to Reproduce: 1. Install granparadiso-alpha1 to desktop directory with that name 2. In shell, cd to granparadiso-alpha1 and run ./firefox & 3. firefox-bin returns the errors above and fails
I'm not speaking from experience, but it seems like you are missing compat-libstdc++-33
Receiving the same error message as Peter the submitter above. Steps to reproduce. 1) Install Fedora Core 6 I downloaded in Dec. 2) Then update all installed packages: Navigate to Applications | System Tools | Software updater tool to update all packages 3) Download Firefox 2 from Mozilla web site 4) extract tar file and run ./firefox The error message "./firefox-bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory" 5) tried Arie's suggestion and went to Applications | Add/Remove Software and searched for the package 'compat-libstdc++-33' and updated suggested package 6) Tried running ./firefox again and now it works. As steps 1 to 4 are what a normal user on the net would do. In my opinion this is still a bug eventhough Aries suggestion fixes it. (ie. I spent the last 2 days searching many forums for solutions and was only able to find it here. Most users would give up and keep using Firefox 1.5 which comes with FC6) Regards, good bug Peter.
No response from reporter in 2 months and this is not a bug in Firefox -> Marking Invalid @jmarbas: The libstdc++5 requirement is specified in the system requirements at http://www.mozilla.com/en-US/firefox/system-requirements.html and the first result of a Google search for [firefox error libstdc++.so.5] is a Mozillazine kb entry with directions to solve this exact error.
