Searching this excellent forum, I can see that there are many others who have had problems installing Optware packages caused by the uClibc issue (cannot resolve symbol __guard). In my case, I am trying to get Rsnapshot running.
Like a fool, I updated the firmware on my new MBWE as soon as I got it to Firmware:02.00.18 and lost the compiler etc. It is a moot point if I would have been able to solve the problem this way but I am certain that I do not have the ability to build a cross-compiling environment as suggested elsewhere.
Is there a simpler solution which could be documented here? I imagine that it is more complex than downloading the appropriate compile libraries etc. but there must be a simple solution to this which might help many of us.
So, HELP PLEASE - oh and I am perfectly willing to offer up my MBWE(1TB) as a guinea pig for this exercise.
