Hi Paolo,

I don't know how much of this is already meant to work, but I run into several issues when compiling the latest code from the meson-poc-next branch.

1. MSYS2-based Windows build: The guide to compile e.g., qemu-system-ppc on Windows with Msys2 works OK to compile Qemu: https://wiki.qemu.org/Hosts/W32#Native_builds_with_MSYS2

However, when I compile the meson-poc-next branch I run into the following error:

hsp@HSP-W10-X64-I7 MINGW64 ~/src/qemu-meson-gitlab/build
$ ../configure --cross-prefix=x86_64-w64-mingw32- --target-list=ppc-softmmu --enable-gtk --enable-sdl

...
Program python3 found: NO
../meson.build:32:0: ERROR: /mingw64/bin/python3 not found
A full log can be found at C:/msys64/home/hsp/src/qemu-meson-gitlab/build/meson-logs/meson-log.txt
ERROR: meson setup failed

2. When cross compiling from Fedora 32 for Windows with

../configure --cross-prefix=x86_64-w64-mingw32- --enable-gtk --enable-sdl --target-list=ppc-softmmu

I get the error below even though the v2 commit message says there is a fix for the absolute path error included:

The Meson build system
Version: 0.55.0
Source dir: /home/hsp/src/qemu-meson-gitlab
Build dir: /home/hsp/src/qemu-meson-gitlab/build
Build type: cross build

../meson.build:1:0: ERROR: prefix value 'c:/Program Files/QEMU' must be an absolute path

A full log can be found at /home/hsp/src/qemu-meson-gitlab/build/meson-logs/meson-log.txt

ERROR: meson setup failed

3. As mentioned earlier here concerning a build on fedora 32 host:

https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg02307.html

Both SDL and GTK Guis do not seem to work, only the vnc server is started.

4. The v2 patch set seems to not apply cleanly to current qemu-master, I get this error:

5: And one question: Should the compiled binary etc be placed in the build directory, or should they go into (in my case) the ppc-softmmu folder as with a default build?

Best,

Howard
