Using yum history. I already tried to undo a trans. Didn't work hence my post. It's also a CentOS7 system. I chose that os for some other things I have running on the headless system.
if it's headless why build the QT version of EGC, the daemon form might be more useful and has fewer dependencies.
So now I'm sort of a rock and a hard place kind of deal. I remember when doing all these libraries initially so I could make my own QT I wanted to rip my hair out... really don't want to go through any more sleepless nights.
why didn't you use the system libraries, if you built the libraries from source then that could easily be your issue.
Also. What can / would I type to see current boost lib that's installed since the error references 1.57.0 ?
rpm -qa and grep can show you the installed packages, ldd might show what libraries you're linking against. Having EGC looking for boost 1.57 suggests something odd in your setup as that's not the version bundled in CentOS. If you're running a website this is probably stuff you should know...
