1. Installed the
yum install rpmforge-release-0.5.3-1.el6.rf.i686.rpm
but still getting the same error.
I do not see what is the reason that you think installing rpmforge will "fix" the error.
The problem is not in rpm forge. The problem is in declared but undefined (non-existing implementation) of functions (functionality).
Still as crazy and loony as before. Even crazier to think that some rpm forge will define funcitonality of non-existing functions (procedures).
2. When you are talking about "shipped with your linux distro", I do not get it: I simply downloaded the entire distro from CentOS, installed it. When I try to search for wxWidgets in "AddRemove software" of CentOS, it is not found anywhere. Not on local machine not on CentOS site.
3. Just continuous waste of time. It appears people have no clue about any solutions, but posting "solutions" here regardless to look like "pros". Deceiving themselves. You loose credibility. You loose users. You make yourself look like loosers. You do not understand one thing: people who post here are not interested in writing in a vicious loop, forever( look, for, solutions).
Same question as before: why do you use a self-build wxWidgets ?
Always prefer the version shipped for your distro (if possible).
Did you try the packages from my repo ?
