This probably means that tk wasn't installed properly.

编译insight-6.8前必须修改insight-6.8的源代码。
1)修改insight-6.8/tk/generic/tk.h
将(line 653)
#define VirtualEvent (LASTEvent)
#define ActivateNotify (LASTEvent + 1)
#define DeactivateNotify (LASTEvent + 2)
#define MouseWheelEvent (LASTEvent + 3)
#define TK_LASTEVENT (LASTEvent + 4)
改为：
#define VirtualEvent (MappingNotify)
#define ActivateNotify (MappingNotify + 1)
#define DeactivateNotify (MappingNotify + 2)
#define MouseWheelEvent (MappingNotify + 3)
#define TK_LASTEVENT (MappingNotify + 4)
并将随后的#define TK_LASTEVENT (LASTEvent + 4)删除(line 661附近)
2)修改insight-6.8/tk/generic/tkBind.c
在line 586和line 587之间增加
#ifdef GenericEvent
/* GenericEvent */ 0,
#endif

经测试，已经可以正常启动arm-linux-insight


补充一下：我安装的tk8.5和tcl8.5
