Hi Larry, I tried your suggestion (also suggested to me off-list), but no change sadly. I am really at a loss here ! :-/ So in despair, I attached a cut-down, single file ( < 60 lines), compileable piece of code that reproduces the problem. Make file comes with it. I can't offer a beer for real via e-mail of course, however I am more than willing to send 2 or 3 Euros (via Paypal) to whoever picks his brain on it and can compile it without getting the warnings below, so he can go buy himself a real beer ! :-) menu.c:35: warning: initialization from incompatible pointer type menu.c:36: warning: initialization from incompatible pointer type menu.c: In function ‘menu_run’: menu.c:44: warning: type qualifiers ignored on function return type menu.c:47: warning: assignment makes pointer from integer without a cast menu.c:48: warning: assignment makes pointer from integer without a cast Thanks in advance to all the participants !..... -- Vince, getting desperate indeed
