do someone have a idea ?

Please provide the steps to reproduce the issue and the source code repository.

[lystrys2030]

I use qemu clone with the command "git clone ..." the offical last version on the github source and I build qemu on the MINGW64 console with this script : "PATH_PREFIX=$HOME/qemu/qemu-8.1
PATH_BINAIRE=$HOME/qemu

cd $PATH_BINAIRE
echo $PATH_PREFIX

./configure --prefix=$HOME/qemu/qemu-8.1
--enable-hax
--enable-libusb
--enable-vvfat
--enable-libudev
--enable-whpx
--cpu=x86_64
--enable-gtk
--target-list=x86_64-softmmu
--cross-prefix=x86_64-w64-mingw32-
--libdir=c/msys64/mingw64/lib
--libexecdir=/c/msys64/mingw64/bin
--includedir=/c/msys64/mingw64/include
--bindir=/home/lystrys/qemu/build/qemu-8.1/exe "

[Biswa96]

I can not reproduce the error. Here is what I did.

1. Install all the dependencies.

cd MINGW-packages/mingw-w64-qemu
makepkg-mingw -seoc

2. Clone the qemu repository.

git clone --depth=1 https://gitlab.com/qemu-project/qemu.git

3. Configure the build

cd qemu
./configure \
--enable-hax \
--enable-libusb \
--enable-vvfat \
--enable-libudev \
--enable-whpx \
--cpu=x86_64 \
--enable-gtk \
--target-list=x86_64-softmmu

Though I did get the following warning, it can be ignored.

ln: failed to create symbolic link 'x86_64-softmmu/qemu-system-x86_64.exe': No such file or directory

[lystrys2030]

think I go to try like this

[lystrys2030]

I don't find this command "cd MINGW-packages/mingw-w64-qemu
makepkg-mingw -seoc" where do you find it ? not in the source qemu repertory ...

[Biswa96]

That step is optional and just to make the installation of dependencies easier. That directory is this repository. You can install the dependencies manually.

I 've this error so I find the solution with reference link issue : bincrafters/community#1089

I can run configure any ,problem I just try to build qemu in present et see if there's not problem

[Biswa96]

try without --cross-prefix option.

[lystrys2030]

so when I execute the "make" I've this error

I need to investing the problem again

[lystrys2030]

well I desinstall qemu and download this version

I execute this command :

./configure --prefix=$HOME/qemu-8.1 \

--cpu=x86_64
--enable-gtk
--target-list=x86_64-softmmu
--enable-libusb
--libdir=/c/msys64/mingw64/lib
--libexecdir=/c/msys64/mingw64/bin
--includedir=/c/msys64/mingw64/include
--localedir=/msys64/mingw64/share

for instant the configure and make is ok

[lystrys2030]

you could read on discord history discussion the result after the run "make install"
