[Qemu-devel] qemu-i386 segfaults when running wine on a x86 CPU?

[James Supancic]

When I run
qemu-i386 /usr/bin/wine
I get
qemu: uncaught target signal 11 (Segmentation fault) - exiting

I am using the wine version I compiled and installed for my x86 host, not
the one from the qemu website. Do I have to compile my wine version with
some special options to use it with qemu-i386 or set some special
configuration settings?

I know I don't need qemu-i386 to run wine compiled for x86 CPUs on an x86
CPU. I am trying to figure out how to make a version of wine that will work
with qemu-i386, after I figure this out I intend to move the wine
installation over to a sparc CPU.

Thank you for your time,
 James Supancic

Qemu's user mode emulation only works for Linux -> Linux at the moment,
i.e. programs compiled for Linux can be run on a Linux host. (The useful
part is of course that programs compiled for a different CPU
architecture than the host's can be run.)

However, encouraging progress has been made on qemu-darwin-user, which
will do what you want to do. See here:

But, I am using a version of wine on Linux compiled for Linux? wine is a
Linux program is it not?

I got the segfault when I ran
qemu-i386 /usr/bin/wine

when I run file /usr/bin/wine I get
/usr/bin/wine: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.4.1, dynamically linked (uses shared libs), stripped.

I should be able to run 32-bit ELF executable compiled for Intel 80386 CPUs
with qemu-i386, shouldn't I?

Note that, I didn't even try to run a Win32 executable with wine, I just
tried to run "wine", it should have printed its command line options/help
and exited without doing anything strange...

Thank you for your time,

Oops, I wasn't paying attention and thought your message was posted to
darwine-devel. Sorry!

Well, partly so. It actually does quite a lot of fiddling to fake a 
Windows memory layout for one. I remember that there were some problems 
with stack protectors and other permission restricting Linux setups. It 
should be possible to support that startup routine, though.

Just out of interest: Are you running with or without kqemu?
