I've been trying to run this ( paint.hs) program ,shown below, in ghci - but I get this error I don't know how to correct :<br><br>
Loading package wxcore-0.13.2 ... can't load .so/.DLL for: stdc++
(libstdc++.so: cannot open shared object file: No such file or
directory)<br><br>
Does anyone know the fix for it? ( I got the same thing with the other sample programs for wxHaskell)<br>
