when I import all the GA Library files and "Build" it, it shows (In VC++ 2005 Express Edition)....
 
 
Creating library...

ga - 0 error(s), 7 warning(s)



 
 
 
Ignoring the warnings when I import  an example from the 'examples' given with "galib246", then it's showing many errors.I'm sending those errors for the example(ex9.cpp) I used.
