Can anyone please help me with a short example Perl script that will print
out all the odd numbers between 1 and 10?  I don't know Perl and am trying
to learn it.  I wrote a bash script to do the same thing and wanted to
compare it.

There must be a Perl expert out there somewhere who can help me?

Thanks-
Scott

Re: Perl

[Scott@Charter]

Then why do these groups exist?  Did you ever stop and think that maybe I am
in a rush?  Did you ever stop and think that maybe I am unemployed, looking
for a job, and can't afford a book?  Did you ever stop and think that there
are kind, intelligent people out there who are willing and happy to just
answer questions politely that are asked politely?  I guess we can't all
have your flare for life!

Go spread your cheer in the grumpy user group. (and I'm being nice)  There
are nice people out there who are willing to help me out.  Some people just
want/need a little help with certain things.  Why did you become a member of
this group?

Besides, I have a useless Perl book.

Re: Perl

[Richard Nairn]

Scott,

The issue is that you have sent about a dozen messages, which show little 
effort on your part to try and figure out these basic problems. Quite 
frankly, if you are unable to do these, which you say is a screening 
portion of an interview, that how do you expect to show any compentance 
within the realm if you get past that part.  For a large part (and I don't 
speak for the entire list) everyone is willing to pitch in, if we can see 
that a reasonable effort has been shown, or if someone has a non-trivial 
problem. I still stand by what I said earlier, you are trying to get us to 
do your work for you. The web has a wealth of introductory material for 
all sorts of stuff. Get your feet wet. If you can't afford a book, go to 
the library, or search the web for reference material.

This list is an admin list, not a learn to program bash or perl group. It 
isn't that we don't want to help. But help yourself first. You won't get a 
job if you don't know basic fundamentals.

That said, for printing odd numbers 1-10. you can do it either of a few 
ways. One is simply to start at one and increment by 2 which will give you 
odd numbers all the way. Or if you want to be different, increment by one, 
and use % operator to find numbers that aren't divisible by 2.

#!/usr/bin/perl
for ($i=1; $i < 10 ; $i++)
{
   if ($i%2 !=0)
{
     print "$i\n";
}
}

for ($i=1 ; $i < 10 ; $i+=2)
{
    print "$i\n";
}

Good luck on the job hunt.

Dude,

Relax.  To get good info out of lists come prepared with good questions.  
Especially be prepared for "RTFM".

This list is sparse. But, the best lists I belong to will give you the 
same "grumpy" 
response if your questions are posted like this one.

Don't mean to be cheerless.

Re: Perl

[Adam Lang]

Email lists do not exist to do all the work for you.  You tend to get the
best results in situations where it is "I am trying to do such and such and
such.  This is the config I am using and this is the error I am getting.  I
searched google for an answer, but the solution I found didn't help.  any
ideas?"

People are not here to do the work.  They are here to offer advice and a
push in the right to direction to help get past sticking points.

As for saying "you're in a rush", that is probably the WORST thing you can
say on these lists.  Just about everyone on here is at work and doing their
own job. It is rude and tacky to assume your problems are so important that
you can't do initial research yourself, but we can take time out of our day
to help you because you are lazy.

As for the "afford a book excuse", it has no bearing.  When it comes to
programming, there is SO much documentation and examples online, that the
only reason to buy a book is to have an ordered hard copy reference
material.

Just keep in mind that the "intelligent and friendly people" that are on
lists, are typically at work and very busy themselves.  No one is obligated
to answer your questions and you will see the well run dry if you continue
to expect others to do your work.

Re: Perl

[Bradley Hook]

You would be better off in IRC for quick questions. These mailing lists 
go to a lot of people, so lots of small beginner questions that aren't 
exactly on topic (this isn't a PERL list) will just annoy people. In IRC 
you will likely get a faster response, and thousands of people will be 
spared the 20+ emails that have been generated from your discussion so far.

I would recommend EFNet or Freenode, as I've found lots of helpful folks 
on those networks.

Re: Perl

[Bradley D. Thornton]

Hi Scott :(

Seems you misundertand what these lists are for. These lists are for people
to help people who are helping theirselves, and for people who are helping
themselves receive help from people who want to help people helping
themselves.

There are two things you are going to see when you post something like the
thread you just did, and to varying degrees:

1.) RTFM

2.) STFW

You've already received suggestions like that so I won't bother engaging in
a redundant act.

Now, If you're looking for a job as a Perl programmer and the book you have
isn't doing it for you (and you don't have the money to buy another one),
you prolly shouldn't be looking for a job programming in Perl.

Also, Oreilly has books online for  you, some they charge for but the perl
book is free if you look for it. You can even print a hard copy if you have
enough paper.

Next time, instead of asking someone to "Do it for you", why don't you try
posting your broken code here (or on a list that is more on topic), pointing
out to the rest of us where you think the program is bombing?

You should also prolly d/l OpenPerlIDE at sourceforge, if you're running a
wynd0z3 workstation, it's got a lot of help.

Finally, since you site a lack of money, there are lots of self help
tutorials out there for Perl as well - but if you still want someone to "Do
it for you", instead of "Help you", then I'm your man. Simply lemme know
your fax number and I'll shoot you on over my Technical Services Agreement,
then you sign and fax back. Then I'll write the application for you :)
There's a one hour minimum, of course, so you will be billed for one hour at
$85.00/hr.

Re: Perl

[Bradley D. Thornton]

Well it seems that our friend (NOT), scott.smallsreed@charter.net is a
certifiable bonehead. I just received a response from him with some pretty
colorful language - dayglow, I would say ;)

Scott, I'm not going to dignify your filthy comments by responding to that
email, but your original post, which was is only five days old, certainly
doesn't show the level of your animosity that you shared with me privately.

If that O'Reilly book is too much for you then perhaps this isn't the thing
for you after all. It's an RTFM world out there, and you'll only last one or
two days on the job anyway if you can't swim in that pond.

Since you feel such anger against everyone on these lists, then perhaps it
is best if you just stick to your job as a plumber ;)

One more thing - if you didn't care, then why did you send such a long
private flame? ;)

TTFN.

Nico,

Yes, there are people who know how to explain things properly, and with
class.  To those of you who noticed I discontinued asking questions several
days ago.  To be blind sided, and flamed, like the other guy did, several
days after the question was asked, was completely inappropriate.

I've never seen Bradley Thornton actually ever answer questions but only
flame me.  I think that's all he's good for.  Then he hides behind a news
group.

Thanks Nico!

foreach ( 1 .. 10 ) {
  print "$_ " if ($_ % 2 == 1);
}

".." is an operator that will return a list that is the range between left
and right.  foreach will run the code block for each item of the list,
setting $_ to that item.  print ... if does like it sounds, and % is the
modulo operator, in other words, it returns the remainder if the % had been
a /.

I hope this helps you, and I apologize for the unkind responses you have
received from the list here.

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?

[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.

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.

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%]

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,

I don't understand.  Is this part of a bash script?
It looks like you a trying to assign the fifth parameter 
(path=$5) to a variable named path (which BTW is not the
PATH) and then manipulate it in some way (something to do 
with \ I think).

Perhaps this is some language that I am unfamiliar with?
If so, I apologize.  However, if is bash, I suggest you 
explain in words what you want to do, and I will try to
script it.
