How to compile QEMU on Win64

[TheCollector1988]

Since the following site URL http://virtuallyfun.superglobalmegacorp.com/?p=3092 no longer provides newer versions of QEMU for Win32 (such as 1.5.x), I decided to put my own guide here (if it's on-topic)

First major step: prepare the MinGW 64-bit environment for the dependency components of QEMU
Requirements
Get the MinGW-w64 package from here:
http://mingw-w64.sourceforge.net/downlo ... ngw-builds
And check the downloads, and, in the installer of MinGW 64-bit, use the sjsj exception, use gcc 4.8.1, and win32 thread and rev1.
However, this does not install MSYS by default, so you need to get it separately, from here: http://sourceforge.net/projects/mingw-w ... 32-bit%29/

Install Python 2.7 from here:
http://www.python.org/download/releases/2.7/
Accept the default directory it gives (C:\Python27).
After being installed, make a copy of python.exe as python2.5.exe.

Once gotten, we can start compiling the dependencies.

1)
Get the latest release of libffi from here:
http://www.mirrorservice.org/sites/sour ... ub/libffi/
compile it with:

Code: Select all

./configure --prefix=/c/mingw-builds/mingw64 --build=x86_64-w64-mingw32
make
make install

2)
Get libiconv-1.14 from here:
http://ftp.gnu.org/pub/gnu/libiconv/lib ... .14.tar.gz
compile it with:

Code: Select all

./configure --prefix=/c/mingw-builds/mingw64 --build=x86_64-w64-mingw32
make
make install

3)
Get the latest release of gettext from here:
http://ftp.gnu.org/gnu/gettext/
compile it with the following options:

Code: Select all

./configure --prefix=/c/mingw-builds/mingw64 --enable-threads=win32 --enable-relocatable --build=x86_64-w64-mingw32
make
make install

Watch out! You need to use these in the shell of MSYS every time you need to compile Glib and Qemu:

Code: Select all

PATH=/c/Python27:/c/Python27/DLLs:$PATH
export PATH

4)
Watch out again! As explained in the official Qemu website, Glib 2.23 and higher in x64 mode won't make Qemu work!.
Get glib for win64 here (x64):
http://www.gtk.org/download/win64.php (grab the sources instead of the dev and bin)
compile it first with:

Code: Select all

export LIBFFI_CFLAGS='-I /c/mingw-builds/mingw64/lib/libffi-3.0.13/include'
export LIBFFI_LIBS=-lffi
export lt_cv_deplibs_check_method="pass_all"
export CFLAGS="-O0 -g -pipe -Wall -mms-bitfields -mthreads"
export CPPFLAGS="-DG_ATOMIC_OP_USE_GCC_BUILTINS=1"
configure -prefix=/c/mingw-builds/mingw64 -with-pcre=internal -disable-static -disable-gtk-doc -enable-silent-rules -build=x86_64-w64-mingw32
make
make install

Fixes for the glib compile failures about libintl.h: Glib can't find the right path to libintl.h, so you need to copy it to the glib-2.26.1 directory and modify configure (the file), search "libintl.h" (with quotes) and replace it with your path of the include directory containing libintl.h (in this case: c:/mingw-builds/mingw64/include/libintl.h)

5)
Grab pkg-config from here:
http://pkgconfig.freedesktop.org/releases/
compile it with:

Code: Select all

export GLIB_CFLAGS="-I /c/mingw-builds/mingw64/include/glib-2.0 -I /c/mingw-builds/mingw64/lib/glib-2.0/include"
export GLIB_LIBS="-lglib-2.0"
configure -prefix=/c/mingw-builds/mingw64 -build=x86_64-w64-mingw32
make
make install

6)
Rebuild Glib with these options instead:

Code: Select all

configure -prefix=/c/mingw-builds/mingw64 -build=x86_64-w64-mingw32
make
make install

7)
Grab SDL from here:
http://www.libsdl.org/download-1.2.php (Select the mingw32 one)
compile it with:

Code: Select all

configure -prefix=/c/mingw-builds/mingw64 -build=x86_64-w64-mingw32
make
make install

8) (Optional for QEMU versions prior to 1.3)
Grab pixman from here:
http://pkgs.fedoraproject.org/repo/pkgs ... 0a9a15f20/
compile it with:

Code: Select all

configure -prefix=/c/mingw-builds/mingw64 -build=x86_64-w64-mingw32
make
make install

Second and last step, compiling QEMU!
If you want to compile QEMU 1.x, you need to put, every time, the python path to the MSYS shell that is shown above in this tutorial.

Grab the latest git release here:
http://wiki.qemu.org/Main_Page

and start compiling with:

Code: Select all

./configure
make
make install

If anyone's having problems starting QEMU, let me know so I can change this guide.

Thank you for this easy to understand guide

[therock247uk]

very very nice!!

[Terra854]

Do we run the commands using bash?

Do we run the commands using bash?

Yes, everything related to MinGW is done in bash.

Thanks for the guide, also the Cirrus patch seems still having some major problems with Windows 3.1...

Thanks for the guide, also the Cirrus patch seems still having some major problems with Windows 3.1...

I fixed that with an old patch (it was originally for 0.11, from 2009/2010) that was posted on a Japanese website, I might provide it someday but it will need to be edited to be compatible with 1.5 or 1.6.

I believe you got it from here?

hmm im trying to build a new environment got everything compiled and happy but on doing ./configure for qemu i get...

ERROR: "cc" either does not exist or does not work

Code: Select all

export CC=gcc

Although I'm not having much luck with the resulting binary.... and I still have glib2 issues.....

I never was that good at debugging this stuff.

waveOutGetID ... I think is causing my crash. Not sure thought. I've also switched to rebuilding with -O1 flags instead of -O2, as I know that used to annoy the win32 build of Qemu in coroutines-win32.c ... But I get the same crash.

I guess all that is left is to try forcing SDL audio "--audio-drv-list=sdl" or switching to the new/slower backend "--enable-tcg-interpreter"

[TheCollector1988]

use -O0 for no optimizations

[louisw3]

use -O0 for no optimizations

what versions are you using? gcc? glib2?

I'm going to trash all my stuff and rebuild... qemu & glib as O0 and see how that goes.

Ok I'll try those... on the rebuild glib phase I get a bunch of undefined crap... and of course if it does work, it'll just fail as un spectacularly as always...

can you build qemu 1.7.0? I'm trying a bunch of versions, but as always a known working thing is so much easier to start with before deviating.

[DJ Deedahx]

Thanks for this tutorial. I will surely refer to it when I get to download QEMU.

But, really, couldn't they have a separate EXE for noobs?
