If this results in an error for you it looks like a wrong glibconfig.h (where this macro is defined) is used or maybe you use some ancient GTK+ version which had a bug in it. For the reference, I can build wx 2.8.4 just fine under 64 bit Linux and the macro is defined like this here: #define GPOINTER_TO_UINT(p) ((guint) (gulong) (p)) Regards, VZ -- TT-Solutions: wxWidgets consultancy and technical support http://www.tt-solutions.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: wx-users-unsubscribe(a)lists.wxwidgets.org For additional commands, e-mail: wx-users-help(a)lists.wxwidgets.org
