[Qemu-devel] qemu-i386 -L / /usr/bin/perl -e 'print `perl -v`' doesn't print

[Jay Schulist]

Hello,
I have an issue with perl and qemu that I'm hoping someone knows what
is happening. I'm using qemu-i386 on a fedora 11 intel system and the
following command fails:

$ qemu-i386 -L / /usr/bin/perl -e 'print `perl -v`'
qemu: Unsupported syscall: 240

I've included the strace at the end of the message. The command should
give the following output:

$ /usr/bin/perl -e 'print `perl -v`'

Note the following works just fine:

$ qemu-i386 -L / /usr/bin/perl -v
qemu: Unsupported syscall: 240

I am using qemu-i386 v0.11.0 as shown below and other binaries run
under qemu look fine. Could you suggest a way to get this perl command
working.

Thank you,
Jay

$ qemu-i386 -v
qemu-i386 version 0.11.0, Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu-i386 [options] program [arguments...]
Linux CPU emulator (compiled for i386 emulation)

Standard options:
-h                print this help
-g port           wait gdb connection to port
-L path           set the elf interpreter prefix (default=/usr/gnemul/qemu-i386)
-s size           set the stack size in bytes (default=524288)
-cpu model        select CPU (-cpu ? for list)
-drop-ld-preload  drop LD_PRELOAD for target process
-E var=value      sets/modifies targets environment variable(s)
-U var            unsets targets environment variable(s)
-0 argv0          forces target process argv[0] to be argv0

Debug options:
-d options   activate log (logfile=/tmp/qemu.log)
-p pagesize  set the host page size to 'pagesize'
-singlestep  always run in singlestep mode
-strace      log system calls

Environment variables:
QEMU_STRACE       Print system calls and arguments similar to the
                  'strace' program.  Enable by setting to any value.
You can use -E and -U options to set/unset environment variables
for target process.  It is possible to provide several variables
by repeating the option.  For example:
    -E var1=val2 -E var2=val2 -U LD_PRELOAD -U LD_DEBUG
Note that if you provide several changes to single variable
last change will stay in effect.
