I have changed from Ubuntu to Mandriva. Formerly, after I compiled a program, I could click on the icon and it would run. Now, I am asked what program to use to open/run the program (the program - very simple - runs from the command line). I am missing something very basic, but I cannot find out what in numerous web searches. Probably the answer is too obvious. Just not for me.
Thank you. I did right-click the Properties tab and changed some of the permissions and the programs now work. It is a relief to have a simple solution!
