I use the “HTML Validator” Firefox plugin daily. I found it does not work out of the box in Linux namely Fedora Core 6 and Fedora 7. You immediately get a HTML-rendered screen that states:
FATAL ERROR : The dynamic C library contained in the extension file could not be found
Getting rid of this message took me a few minutes of research and I never found a step-by-step HOW-TO for Fedora — so here goes!
Here is how you get rid of this message and get the plugin working in Fedora Core 6 or Fedora 7:
- First, uninstall the plugin by clicking on Tools–>Add-ons and clicking uninstall
- Second, close all instances of Firefox
- Next, install three packages using yum
- compat-libstdc++-296
- compat-libstdc++-33
- tidy
yum install compat-libstdc++-296 compat-libstdc++-33 tidy
- Reinstall the HTML Validator plugin
- Restart Firefox, done!
HTML Validator should now be installed inside of Firefox on Fedora Core 6 or Fedora 7
