This commit breaks building these files on Windows:

     hw/arm/{boot.c,vexpress.c,imx8mp-evk.c,raspi4b.c}

Error is :

     fatal error: libfdt.h: No such file or directory

Thanks,

C.

Is libfdt available in your windows environment? If yes, is it in a non 
standard path?
On my side, it built successfully, so I first need to reproduce this.

Thanks,
Pierrick

Hi Pierrick,

For what it's worth, those files were also breaking on Ubuntu and Debian for me.
I had to explicitly `sudo apt install libfdt-dev` for it to work
again. I don't believe
it was installed at all previously, but QEMU was building and working correctly
without it being explicitly installed.

Thanks,
Nabih

yes. I had to install libfdt-dev/el on some systems too.

However, for the windows (on Linux) build :

   ./configure --cross-prefix=x86_64-w64-mingw32- --target-list=aarch64-softmmu,ppc64-softmmu,x86_64-softmmu,s390x-softmmu --disable-docs --disable-sdl

It's still broken.

Thanks,

Thanks Cédric, I could reproduce it using the fedora-win64-cross 
container. After investigation, it's related to having a target-list, 
and in a specific order (hum, hum, feels bad). I observe the same 
behaviour when building normally for Linux too.

Those 3 commands work as expected:
$ ./configure --target-list=aarch64-softmmu  && \
ninja -C build libsystem_arm.a.p/hw_arm_raspi4b.c.o
$ ./configure && \
ninja -C build libsystem_arm.a.p/hw_arm_raspi4b.c.o
$ ./configure --target-list=s390x-softmmu,aarch64-softmmu && \
ninja -C build libsystem_arm.a.p/hw_arm_raspi4b.c.o

This one fails:
$ ./configure --target-list=aarch64-softmmu,s390x-softmmu && \
ninja -C build libsystem_arm.a.p/hw_arm_raspi4b.c.o

I will investigate more, but I strongly suspect there is a bug in the 
meson libraries patch I wrote, with a variable being reused when it 
should not.
Sorry for the inconvenience.

Regards,
Pierrick
