Compiling for Windows x64

[Maighstir]

Sure, I could just run the 32-bit version, and thanks to the "easy way to build" topic, it's about as easy as can be to even get the latest sources to binaries. Now, though, I was toying with the idea of building a native 64-bit version, but I'm having huge troubles getting the toolchain to even run. I'm sitting on 64-bit Windows - 7 Ultimate, to be exact - and trying to use MinGW-w64, but I'm no stranger to Linux and will use that if setting up a cross-compiling environment in a virtual machine would be easier than messing around in Windows.

 

Any hints?

 

Yes, I know building it for 64-bit doesn't actually give any benefits whatsoever.

 

Oh, yeah, I have two bat files, one for setting up the 64 or 32-bit env (so I can chose what architecture to compile for), and one to actually run the build. Both are listed below.

 

@echo off
:start
set /p userinp=Chose 32-bit (3) or 64-bit (6):
set userinp=%userinp:~0,1%
if "%userinp%"=="3" goto bit32
if "%userinp%"=="6" goto bit64
echo invalid choice
goto start

:bit32
set PATH=%PATH%;c:\mingw\bin;c:\mingw\include;c:\mingw\lib;c:\mingw\include\SDL;c:\mingw\include\AL;C:\MinGW\include\libpng12;

The 64-bit path needs all those FILEPATHs because for some reason it would otherwise use the 32-bit target versions inside C:\MinGW

 

The 32-bit path runs perfectly, but the 64-bit one (x86_64-w64-mingw32-make.exe) complains about not finding a "libintl-8.dll", if I manage to find the file online and put it in C:\MinGW-w64\bin, I only get some error that "the program cannot be run" (I forgot exactly what, sorry, and now I cannot find that DLL either to recreate the error).

Perhaps the file you are looking at is compiled for the 32bit architecture when it can only link to a 64bit DLL.

I recall having had problems with this library, even on 32 bits. It was with one of the mingw package, can't recall which one, sorry...
