MXE and QT deployment gives Runtime Error

Question

I'm building a QT application on Ubuntu that works pretty good. Now I have to deploy it on Windows, so I installed MXE in order to cross compile my sources.

MXE build

git clone https://github.com/mxe/mxe.git
cd mxe
# I need posix threads, that why I build static.posix target
make MXE_TARGETS='i686-w64-mingw32.static.posix' qtbase libxml2

I use a personal library (that uses cmake) and a client/server code for my QT code, that I compiled with MXE and it did not give any error (I worked hard to fix them...). Then, the compilation for the QT reaches the end without any error.

Whenever I try to execute the program (with wine on Ubuntu or on Windows) it does not work. wine freezes and Windows shows me a Runtime Error.

I also tried to use the windeployqt.exe using wine on my executable, hopping it will give me the missing dlls, but it tells me :

Z:\path\release\Executable.exe 32 bit, release executable
Z:\path\release\Executable.exe does not seem to be a Qt executable.

I really have no idea on what is broken. Am I forgetting to put dlls, or is my compilation failing silently ? Does anyone knows or have ideas on how to deal with that case ?

EDIT

Apparently I compile correctly my program, the error seems to come from GetAdapterAdresse when using Windows. The problem is not coming from MXE at all (I'm glad I made it work though).

I'll have to have a look on this function, but anyone knows how to make gdb work with MXE ? When I ran make gdb, it has built something, but I can't figure out where is the program.
