Help for GAlib++

[Ian Wilson]

Down load the galib244-win.zip, that's the quickest and easiest thing to do,
I think.

I found it easier to make the changes to 244, bringing it up to 245, than
starting with 245 and trying to get that to fit into VC++.

The galib244-win provides the necessary project settings, making it much
easier to get going.

Once you have that, build the galib project and then add a reference to the
galib.lib it creates within your projects.

Hope that helps a little.

Ian

P.S. Check under tools, options, directories and make sure you have a the
path to the galib included there.

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.

"..\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:
