Qemu-i386 Options

[Borealid]

Applying the gist of the changes from this message, I have successfully built a qemu-i386 and qemu-img binary on my Zaurus SL-C3100 (inside a Debian chroot).

I hoped to use it to launch wine in user mode, so I grabbed the full i386 deptree of Debian's testing Wine distribution and ran "dpkg -x --instdir=/x86" on each .deb, creating a tree that (theoretically) contains all the x86 binaries and libs that wine needs to run. However, I following Qemu's user-mode documentation, I tried to run /x86/usr/bin/yes and get:

"Unable to load interpreter
Segmentation fault"

The program is able to display its --help just fine.

I'm not at all familiar with cross-compilation and such, which is why I went for the prepackaged i386 environment instead of rolling my own glibc; is the problem there, or is the qemu executable I built somehow bad?

I'd love to get qemu-i386 and wine working together on the Z, and it seems tantalizingly close to possibility... It should be working now, in theory.

Is there any help out there?

I believe that Wine under qemu would probably be a superior solution to a full Windows environment under bochs or the like. Not having the massive overhead of a complete Windows implementation might be helpful.

But either way, it requires CPU emulation - either qemu or bochs.

hello borealid,

sorry, but i have problems with your ipk. first it is not a real ipk, its a *.tar.gz.
this is not the problem. i unpacked it and ran the binary (qemu --help), that works,
but it does not work if i apply it to a linux binary, for instance a simple hello program.
i have a working, but old version of qemu (0.5.3). any hints? i install the gnemul package
(i386 libraries) from the qemu homepage to /usr/gnemul. which libraries you
installed to start wine with qemu? thank you for your help...

i have to apologize. first i should read the whole thread and then write
something that makes more sense than the above:-) sorry...

hello,

i want to report my similar experiences with qemu onboard compilation:

i also applied the above mentioned patches to the sources of qemu 0.7.1 resp.
0.8 and compiled within pocket workstation. first i got some reference errors in
block.c, so i commented out the last lines of it resp. changed the Makefile.
a step by step compilation (starting without the patches) showed that all patches
seem to be necessary, but the result is n both cases an unbelievable slow
qemu-i386 binary. i was not able to compile a static version.

i was only confused by the different debian packages for sdl and that compared
to my linux desktop "sdl static link" was not available.

maybe i will try to compile within dev-img1.5 or cross compile it. but first i
have to setup these, for instance how can i add libsdl-dev to dev-img?!
