Problem for cross compiling to windows 10

[daerlnaxe sur gmail]

Hi,

I don't know at all how to use mingw i tried several days to make cross 
compile, sometimes under msys2 sometimes under ubuntu or even debian, i 
saw errors and errors i tried to remove. On Ubuntu i can compile but i 
have no *.exe at the end, probably a prefix problem but on the wiki page 
i can't understand...

It says i must use msvc i looked at ubuntu 20 and didn't find it on the 
hdd, same for debian11. Installation guide seems to be outdated for 
mingw (perhaps it's me), and at a moment when there is the line to use 
the prefix i saw "msvc-" must have enter "-gcc" after ? Something like 
that ?

I asked on the git, stackexchange, forums that use my native language... 
nothing. I need to understand to use patch, i want to use QEMU on win 10 
with a 3d support on w98. Someone made a patch for it, he refuses to 
help, this option can be forsake, this why i want to understand how to 
compile by myself QEMU (raw). I successfull dit it for Ubuntu, it was 
very easy, but for windows 10 ...

My purpose is also to make a tutorial in my language at the end, when i 
will sure to successfull compile, to help people and promote QEMU for 
retrogaming with win9x games. I tried probably all the others solutions, 
it's the best i saw (virtualbox, vmware, pcem, 86box, dosbox-x, 
Bochs...). It's efficient on a low machine like an old i5 laptop, i 
played thanks to precompiled packages for windows10, to several 2d games 
perfectly. Perfect on my i7 4770k. There is 2 things missing for me:
- a 3d support this is why i want patch it.
- Scanlines & shaders effect, for windows 10 i found ShaderGlass.

I know how to program with tools like Visual Studio, Eclipse, but here 
i'm totally lost and need probably a step by step guide according to the 
last tools.


Best regards.
