Dear Webmaster:
  I am  a graduate in China.I have gotten a copy of GALib++ from your ftp site.The GaLib++ library is a so useful tool for me to do genetic-algorithm related programming.When i was working on it,I have encountered some problems.
I will be very grateful if you can tell me how to deal with these problems.Here is my problem:
when i compiled the GaDemo project with microsoft Visual C++6,I got the following error message: can not open file "..\galib-2.4.4\projects\library\Debug\galib.lib".I browsered through the directory of GaLib++,I could not find the galib.lib. I excluded the galib.lib from the project and got the projected compiled.Howerver,I got the following error message:

   Then I did not know how to do .I am looking forward to your answers.
