strange error in compilation

[quickNitin]

i am having strange error in compilation. I am presenting some part of my header file and output on terminal

class vA1:public QgsMapTool , public QgisPlugin
{

This code is part of a os project so i will not be in a position to post all code. But what i have figured out is it has got something to do with inclusion of some header files.

Similar code is working fine but i am caught here.
