Using glpng in windows with codeblocks

[xanas3712]

I am coming as a user of kdevelop in linux, but I wanted to build a windows version of my application so I went ahead and setup code::blocks for this purpose.

Anyway, I've got everything working (I think anyway) except glpng, which is something I use to make loading png graphics easier.  I have never loaded them manually so I'd hate to have to change what I'm using here.

I get the following errors when trying to use the glpng.lib file (which I have put in code::blocks lib directory)

From the output I guess you're using MinGW, but trying to link against a VC library.

You'll need to build a library for MinGW (.a extension) for this purpose. I guess that information can be found somewhere in glpng's documentation/README/website

 :shock:  Actually not! (glpng is a pretty small project and is not too complex, but it does what I want and that's why I have been using it).

But I figured out how to compile a static lib with codeblocks after reading that someone else had the same issue with DevC++

So it's all good

However, I noticed that I can't resize the application whenever I want to like I can in linux (I use the window resize event with sdl)..

Not sure what is up with it, but it will just create a white screen if I try to resize the display.
