I am compiling a software xchm on solaris 10.
First i run './configure'
There is no error.

But when i start compiling using 'gmake'
following error shown

/usr/local/include/wx-2.6/wx/x11/brush.h: In copy constructor `wxBrush::wxBrush(const wxBrush&)':

Please help me and tell me what is this error and how to solve this problem

Are you using g++ or Sun's Studio-11?

Both g++ and sunstudio 11 installed on my system and make project using gmake

It basically looks like you've got some C++ compilation problems to solve.

I would recommend ensuring that gcc and g++ are used, if that does not solve the problem then you have some work to do fixing somebody's C++ code.
