Hi All ! Probably this is not the correct place to post this question , but I know someone amongst you wise guys will help me out . In the man page of "dlopen" , I came across the gcc compilation command :- gcc -rdynamic -o foo foo.c -ldl But unfortunately , I found that the options are undocumented .i.e. " -rdynamic " & " -ldl " could not be traced in info & man gcc. Can somebody please let me know where I can get more info on this ? Thanks in advance .
