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`' This is perl, v5.10.0 built for i386-linux-thread-multi Copyright 1987-2007, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.

If you have access to the Internet, point your browser at http://www.perl.org/, the Perl Home Page. Note the following works just fine: $ qemu-i386 -L / /usr/bin/perl -v qemu: Unsupported syscall: 240 This is perl, v5.10.0 built for i386-linux-thread-multi Copyright 1987-2007, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.

If you have access to the Internet, point your browser at http://www.perl.org/, the Perl Home Page. 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.
