[Lee Revell]

I've been trying to cross compile Perl for a PPC440 board and it just
isn't happening.  Perl is probably the least amenable application to
cross compiling I've found.

I tried the instructions in the Cross/ directory of the Perl distro but
they don't work - "sh Configure" fails on my target because it expects a
full C development environment, which won't fit.

Is there any easy solution?  Can someone send me a binary?

How do I build a perl binary with it?  I'm not looking to replace my
toolchain or create a full BSP or anything.  I just need a /usr/bin/perl
that will run on PPC440.

buildroot, another rootfs framework, doesn't even try to cross-compile all of 
perl. It does build something called 'miniperl', which is just the perl 
binary without all of the supporting libraries and features. It may be enough 
for you. You can look at the makefile here:

http://buildroot.uclibc.org/cgi-bin/viewcvs.cgi/trunk/buildroot/package/microperl/microperl.mk?rev=11418&view=markup

Configure and make perl natively on your target platform. I have done it 
some time ago with the ELDK.

I don't think this is an option, the perl build has too many
dependencies.

I confirm that building Perl on the target system using the ELDK root
file system over NFS works fine.

Just try it out. It may be slow, but CPU cyles are cheap.

I've done this successfully with ELDK 4.0 and 3.1.1 on PPC440EP Yosemite
board. Resulting perl binary is working with ELDK ppc_4xx filesystem
(linux 2.6.13 has been used).

However it doesn't run on original Yosemite filesystem (I've copied all
perl files there) - it doesn't find certain glibc symbols. With ELDK 4.0
it's quite understood - it uses glibc 2.3.4, while my filesystem has
glibc 2.3.1. But ELDK 3.1.1 has glibc 2.3.1, yet when I try to run perl,
natively compiled with ELDK 3.1.1 fs on my fs (glibc 2.3.1 as well), it
says:

tmp # /opt/bin/perl warnings.pl
/opt/bin/perl: relocation error: /opt/bin/perl: symbol __floatsidf,
version GLIBC_2.3.2 not defined in file libc.so.6 wie

When I copy libc-2.3.1.so from ELDK filesystem to ours, it fails:

/tmp # /opt/bin/perl warnings.pl
Segmentation fault
=20
Did I something wrong?

Thanks,

Leonid.

What is your "original" filesystem? Any standard distro, or what?

Looks as if you used the ppc_4xx packages for  this,  which  are  for
FPU-less  4xx  processors.  On  the  yosemite,  you  should  use  the
ppc_4xxFP tools instead.

Yes. You mixed soft-fload and hard-float binaries and libraries.

[Leonid] The one, supplied by AMCC with Yosemite board - came from DENX
originally I believe though I'm not sure.

[Leonid] That must be it! I'll recompile, using ppc_4xxFP target.

Thanks a lot,

I've almost got the cross compile method described in INSTALL to work
(using SSH to the target).  But it just hangs forever at "Checking how
to flush all pending stdio output...".  Argh.

Compiling natively on the target is not an option, the perl build
process has too many dependencies.  It depends on stuff fron GNU
coreutils like /bin/comm that is not available in busybox.

Does no one out there have a binary they are willing to send me?

    You can also use something like a Mac PowerBook with ppc4xx 
crosstools as a build and test environment.
    I did most of my early link port work that way, though I now use 
crosstools under colinux.

Agreed.

Compile natively on the board, using a NFS root environment.

Hi Lee,

there's a quick'n'dirty way to get a perl running on your CPU.
Take the Fedora Core 4 ppc binary rpm (perl-5.8.6-15.ppc.rpm) and install it 
from an ELDK 4 root filesystem:

bash-3.00# rpm -ihv --nodeps perl-5.8.6-15.ppc.rpm
warning: perl-5.8.6-15.ppc.rpm: Header V3 DSA signature: NOKEY, key ID

   1:perl                   ########################################### [100%]
bash-3.00# perl -v

This will only work if you are running on a system where your CPU has
a full-blown CPU,  32  bytes  cache  line  size,  and  your  run-time
environment (all system libraries) are configured to use the FPU.

It will fail on  FPU-less  or  FPU-restricted  systems  like  MPC8xx,
PPC4xx, or MPC85xx.

I guess you didn't do much testing. You should try some  mathematics,
and  you  might  be surprised what happens when your Perl binary uses
the (emulated) FPU, while the system libraries use soft-float.

Re: Perl

Hi Wolfgang,

I used FC4 ppc binaries for some testing. xlibs, xterm and python where 
the first packages I did some tests with. It was just a try to see what 
happens.

FPU emulation was the first I needed (of course). Then I switched to the ELDK 
ppc_4xxFP root filesystem. This makes it even possible to use perl with math:

bash-3.00# perl -e 'print ("sin(pi/2)=",sin(3.14/2),"\n")'
sin(pi/2)=0.999999682931835
bash-3.00# perl -e 'print ("sqrt(3)=",sqrt(3),"\n")'
sqrt(3)=1.73205080756888
bash-3.00# cat /proc/cpuinfo
processor       : 0
cpu             : 405GPr
clock           : 399MHz
revision        : 9.81 (pvr 5091 0951)
bogomips        : 495.61
machine         : esd CPCI-405
plb bus clock   : 133MHz
pci bus clock   : 33MHz
bash-3.00#  

I would not recommend to use this for production. But its a good starting 
point before turning on the compiler :-)

I don't know much about the ppc440 and it's core. But maybe you
can use mine?!
I am using perl successfully on a MPC8540 CPU which has an e500
core w/o an FPU. I don't need to cross compile and it comes with
only the necessary dependencies:

$ prt-get deptree perl
-- dependencies ([i] = installed, '-->' = seen before)
[i] perl
[i]   db
[i]   gdbm

all that on top of glibc-2.3.4
If you want to try those three tar.gz's please contact me off list
and I can send it to you.
It's also possible to recompile that stuff to a different ppc target...

Greets,

Just found this (notes!) :-

'Perl 5.6.4

Copy the etc/Digest directory from perl-5.8.2

Enable MD5 to be statically loaded in perl sh Configure

Also enable threaded'

Is this a cross compile or a native build you're describing?  If it's a
cross compile do you use the method from Cross/README or INSTALL in the
perl directory?
