Here I had to add "-Ud_eaccess" to avoid a compilation bug.

Perl will still not finish to compile, stopping with this error message:

Executing the last command alone provides this error hinting at a problem 
with host-qemu, which I was able to solve yet.

$ /home/bernd/.fbr/build/output/build/perl-5.16.1/Cross/run-qemu-i386

LIBPERL_A=libperl.so

qemu: Unsupported syscall: 240

First I got this error message with Debian Squeeze i386 (virtualbox guest, 
Win XP host), but also on Debian wheezy amd64 running non-virtualized.

My .config can be found here: http://pastebin.com/yz1SzeB2
I am using buildroot as part of the FLI4L source package[1].

Kind regards, Bernd

I could reproduce the lastest problem on the HEAD of Buildroot with
qemu_x86_defconfig (which is a smaller config than your FLI4L config).

  Is it possible that this is because the target binary is created with
kernel headers 3.2, but you're running it on a host which is only 2.6.32
(squeeze)?  But then it should work on wheezy, because that has 3.2 as
well (at least since about four months IIRC).  Although...  240 on i386
is futex, which has existed already since long before 2.6.32.

  I do find this bug report:
https://bugs.launchpad.net/ubuntu/+source/qemu-linaro/+bug/758424
but I'm not sure if it is relevant.

  Regards,
  Arnout

Aaah, I didn't think about this problem. This is indeed going to be
really annoying, if the kernel headers chosen for the target have to
somewhat match the kernel version running on the host :-(

I guess this whole qemu thing for Perl is going to be annoying on the
long term. We might need to start looking for a different option, i.e
seeing how to get Perl to build without needing qemu.

Best regards,

Thomas

first, before manually running a command in the build tree, you must
set PERL_MM_OPT
   $ export PERL_MM_OPT="PERL=`pwd`/Cross/miniperl"

the error
    -1 from cpan/Archive-Extract's Makefile.PL at make_ext.pl line 409.
comes from miniperl which fails with a 'system' call.

this problem could be reproduced with a simple one-liner :

$ perl -e "my \$code = system( q(echo), q(hello) ); print(\$code);"
hello
0

$ Cross/miniperl -e "my \$code = system( q(echo), q(hello) ); print(\$code);"
-1

after an installation on the target, this 'miniperl' works fine.
so, the problem comes from Qemu.

I write a small C example :

$ cat sys.c
#include <stdio.h>
#include <stdlib.h>

int main()
{
 	int ret = system("echo hello");
	printf("%d\n", ret);
}

$ ../../host/usr/bin/i686-buildroot-linux-uclibc-gcc -o sys sys.c
$ file sys
sys: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), not stripped
$ ../../host/usr/bin/qemu-i386 ./sys
-1

I also try on various architecture.
I build Perl successfully with qemu-arm and qemu-mips,
the problem occurs with qemu-i386 and qemu-x86_64,
with a qemu-i386 version 1.2.0 built with Buildroot and with a
qemu-i386 version 1.0.50 which comes my distro Ubuntu 12.04 LTS.

Other bad new, these days, the homepage of Qemu (http://wiki.qemu.org) is down.

Hi,

on wheezy I am using kernel 3.5.5.

$ LC_ALL=C apt-cache policy linux-image-3.5-trunk-amd64
linux-image-3.5-trunk-amd64:
  Installed: 3.5.5-1~experimental.1
  Candidate: 3.5.5-1~experimental.1

Kind regards, Bernd

Hi,

maybe this can be of help: http://perlcross.berlios.de/

Kind regards, Bernd

PS: The reason I am fiddling around with Perl is to compile 
Mail::Spamassassin which needs a lot of other modules.

  That sounds like a terrific idea!  Do you feel up to integrating this in
buildroot and sending a patch?

  In that case, I'll try to take a look at it this evening.

  We really need to get this perl mess fixed for the 2012.11 release...

  (Francois, with that I don't want to imply that you did a bad job. On the
contrary, getting the build with qemu running was an important step even if
it will have to be replaced eventually.)
