Hi,

I attempted to cross= compile Qemu for Windows from the meson branch today using a Fedora 32 VM = and using MSYS2 .

In both cases I compiled usi= ng:
=C2=A0./configure --cross-prefix=3Dx86_64-w64-mingw32- --targ= et-list=3Dppc-softmmu --enable-gtk --enable-sdl

For the builds to run on Windows I normally copy the pc-bios folder and t= he required dlls (from \msys64\mingw64\bin for the MSYS2 build and from /us= r/x86_64-w64-mingw32/sys-root/mingw/bin for the Fedora based build).
This has always worked in the past.

As= noticed earlier in discussion with Paolo, with MSYS2 there appears to be a= difference in how grep works on Linux and Windows. Using grep 3.1 as provi= ded by MSYS2, the file config-all-devices.mak file stays empty.
<= br>
On Fedora the compilation process completed successfully. How= ever, the binary crashes. This is the backtrace I could get:

I investigated a = bit further and saw:
ldd in Fedora tells me the executable is "not a dynamic executabl= e".

Meson seems to default to try a static build and= enable pie, whereas a normal build would require --static to enable that a= nd have pie=3Dno
