Hi there, I am new to the codeblocks forum! I have posted this on stack overflow a couple of days ago, and haven't recieved any responses, so I thought I would try my luck here aswell...
I have set up a mingw cross-compiler (i686-w64-mingw32) to compile a windows .exe on ubuntu with the Codeblocks IDE. My "hello world" test shows this to be working. I am now trying to cross-compile my full app which statically links to a number of SDL2 libraries. I am facing this list of errors:

I have done a bit of research, and from what I gather, it is because SDL2 wants to dynamically link to some of the windows system libraries. I have also gathered that either mingw or SDL2 comes with the resources to resolve these issues, but I can't figure out what or where these are. While some resources seem to solve the issue, I can never totally follow what the solution actually was. Here are a small selection of the resources I have found on stackoverflow that I think are relevant:
http://stackoverflow.com/questions/28260245/receiving-undefined-references-to-various-windows-libraries-when-compiling-withhttp://stackoverflow.com/questions/19396669/wxwidgets-how-to-cross-compile-an-application-for-windows-from-linux-using-codebhttp://stackoverflow.com/questions/30157718/linking-libcurl-while-cross-compiling-with-mingw32-under-linux-for-windowsThe first link lists the .dlls that SDL2 wants to link to. The solution didn't however mention how to link to them. I have found all these libraries on my windows machine, and I did naively attempt to put them in my project folder and dynamically link them, but ubuntu doesn't recognise the .dlls.
The second link is regarding cross-compiling a wxWidgets app for windows, from ubuntu, using Codeblocks IDE. A particular couple of lines from the solution interest me. They regard setting up the compiler.
Compiler Settings > Other Options : `/usr/local/i586-mingw32/bin/wx-config --cxxflags`
Linker Settings > Other Options : `/usr/local/i586-mingw32/bin/wx-config --libs`
This is the only part of the solution's compiler setup that differ from my own compiler setup. I have nothing in either of these "Other Options" sections. Obviously the particular filepaths/filenames relate to wxWidgets specifically, but I was wondering if I would need to find some similar files for my SDL2 libraries? I have had a scout around the file system, and no luck.
The third link discusses linking to a .dll, by cross-compiling it in mingw first. I don't understand all the instructions there, maybe because I've had my life sugarcoated with IDE's and have never dealt with the nitty-gritty of compiling a program, regardless, I am fairly certain this resource is relevant.
Any help will be much appreciated!
Pete.
