I encountered a problem in installing GAlib graphic's examples on Linux
According to the instruction from the web, after typing:
To build the graphic examples:
            % cd examples/graphic; make

I got such error during compilation:

[root at localhost graphic]# make
g++ -Wall -O -g -DUSE_MOTIF -I../.. -c tspview.C
tspview.C: In function 'void DrawCB(_WidgetRec*, void*, void*)':

tspview.C:675: error: invalid function declaration

If any one have encountered such compilation error and solved it, please
