Subject: Perl pp error: Seeking some info
Date: Tue, 6 May 2014 20:50:55 +0000
To: "autrijus [...] autrijus.org" <autrijus [...] autrijus.org>
From: "Das, Angan" <angan.das [...] intel.com>
Hi Autrijus, We are trying to use "pp" to compile a Perl-based software developed in-house here at Intel. I have tried perlcc earlier but not with much success. The requirement it might have packages which might call other packages. But once compiled into a binary, it should be truly stand-alone: i.e., able to run from any 64-bit Unix terminal, without assuming any dependencies on Perl whatsoever. What I did is the plain vanilla way: $ pp -o <output>.exe <myfile.pl> When I try the '-help' on the executable on another terminal, I get: $ <output>.exe --help Attempt to reload Scalar/Util.pm aborted. Compilation failed in require at /usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/Compress/Zlib.pm line 8. BEGIN failed--compilation aborted at /usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/Compress/Zlib.pm line 8. Compilation failed in require at -e line 358. It seems I might be missing something. I tried compiling with the few options (-B, -M, etc.) mentioned on the website but not with much success. Could you please help asap? Thanks, Angan

Hi Angan, PAR::Packer should fulfill that requirement :) There's little information in your report to diagnose the problem. Please answer the questions below: - which operating system - which version of Perl: please provide the output of "perl -v" and "perl -V" - where did you get PAR::Packer from: - did you build it yourself (using "cpan" or similar)? - if yes, did you run the test suite and did it pass? - does the problem happen with a trivial script, e.g. $ pp -o hello.exe -e 'print "hello, world\n"' $ ./hello.exe - if not, please provide a minimal example BTW, it's not necessary to explicitly CC any maintainers of the module - they are subscribed to rt.cpan.org anyway. Cheers, Roderich

Hi Angan, PAR::Packer should fulfill that requirement :) There's little information in your report to diagnose the problem. Please answer the questions below: - which operating system Suse on SLES10 and SLES11 machines - which version of Perl: please provide the output of "perl -v" and "perl -V" /usr/bin/perl -v This is perl, v5.8.8 built for x86_64-linux-thread-multi - where did you get PAR::Packer from: - did you build it yourself (using "cpan" or similar)? - if yes, did you run the test suite and did it pass? I tried to build it myself but then noticed its already installed in our environment by the env-team. And so what it implies is its already installed property and tested. /usr/intel/pkgs/perl/5.14.1/bin/pp - does the problem happen with a trivial script, e.g. $ pp -o hello.exe -e 'print "hello, world\n"' $ ./hello.exe Yes and no both. I tried running it on a different setup (basically some shell variables set) and it ran fine. I tried running it on a fresh xterm and it ran fine. However, its failing in some particular xterm in some particular setup. I am sure it would be a setup related problem. But I want to rootcause it or narrow down the case. Also, once compiled on Suse-64, will it run fine across all other OS-es – Redhat, Ubuntu, etc. - if not, please provide a minimal example BTW, it's not necessary to explicitly CC any maintainers of the module - they are subscribed to rt.cpan.org anyway.

Then the above Perl version is irrelevant (that's the distro's Perl), this PAR::Packer (including the pp Perl script) were most likely built against a local (though pre-packaged) Perl installation (guessing from the filename, Perl 5.14.1). Could you please provide the output of "/usr/intel/pkgs/perl/5.14.1/bin/perl -v" and "/usr/intel/pkgs/perl/5.14.1/bin/perl -V". Also check that the first line of /usr/intel/pkgs/perl/5.14.1/bin/pp is #!/usr/intel/pkgs/perl/5.14.1/bin/perl I'm pretty confident that PAR::Packer builds (and works) correctly for the distro Perl of any major Linux distro (Redhat, Suse, Debian etc - some might even package PAR::Packer), but locally built Perl installations might be broken in subtle ways. This might not show with most Perl modules, but PAR::Packer is very peculiar and unlike any other Perl module. That's why I asked for the "hello world" example. If this doesn't run in any scenario, you're PAR::Packer installation is definitely broken. Show quoted text

When it fails - what's the error message? Things to look out for are environment variables PERL5LIB (generally anything starting with PERL), PATH, LD_LIBRARY_PATH. Though - at least in theory - the resulting executable should be immune to these. Show quoted text

Yes. It's as portable to any other 64-bit Linux on the same hardware architecture as any executable that you built by compiling and linking a, say, C program. BTW, pp is not *compiling* your script in any way - it packs up the perl executable and all modules used (recursively) by your script into a zip and prepends the zip with a small program that will extract the stuff into a temp directory and run it from there.

Is there any way to pack all the modules/packages also in the compiled script? For e.g., remove all /usr/bin/ kind of dependencies b'cos I see them as strings inside the compiled binary. And when I remove those paths (since it needs to be shipped to an external customer) thru hacky edits, I see a segmentation fault during my run. - Angan Show quoted text

For e.g. attached is the file containing grep of all *intel* strings out of my pp compiled binary. I want to know if there are any dependencies on these paths. For e.g., whether the binary/compiled/packed script will break on some non-Intel environment. And if not, why does it break and give segmentation fault when I search-and-replace all "/usr/intel" within it to "/usr/test" and rerun the script in Intel environment (during my testing)? - Angan Show quoted text

No. The packed executable is self-contained and doesn't need anything from the original packing site. The strings you saw are # line commentes (see the perlsyn man page for "Plain Old Comments"). Their purpose is so that die() or warn() messages mention the original filename and line number though the actual files when running the executable may have totally different names (or might not be files at all). BTW regarding "my pp compiled binary": pp does *not* compile your perl script in any way. Think of the resulting executable a self-extracting archive that contains your script, any required modules and even a perl binary. Cheers, Roderich

Roderich, Thanks for the help. This brings me to my earlier 2nd question --- If they are truly comments, why do I get segmentation fault when I search-and-replace all "intel" with "TEST" (things however pass with "intel" changed to "INTEL"). Could you kindly take a look at the grepped "intel" strings (file re-attached) and let me know. - Angan Show quoted text

Because you destroy the integrity of the data structure of the packed executable. You must not modify it in any way. Cheers, Roderich

If it is a comment, I am not sure what " integrity" is lost when I change /usr/intel/bin/ to /usr/TEST/bin. Either it is relying on the path or it is not. Could you please see the non-comment lines like the ones below. Why is "gcc" coming in the picture? /usr/intel/pkgs/perl/5.14.1/lib64/site_perl/x86_64-linux /usr/intel/pkgs/perl/5.14.1/lib64/site_perl /usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/x86_64-linux archlib='/usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/x86_64-linux' archlibexp='/usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/x86_64-linux' bin='/usr/intel/pkgs/perl/5.14.1/bin' binexp='/usr/intel/pkgs/perl/5.14.1/bin' cc='/usr/intel/pkgs/gcc/4.5.2/bin/gcc' ccdlflags='-Wl,-E -Wl,-rpath,/usr/intel/pkgs/perl/5.14.1/lib64/5.14.1/x86_64-linux/CORE' ccflags='-O2 -fPIC -I/usr/intel/pkgs/perl/5.14.1/include -L/usr/intel/pkgs/perl/5.14.1/lib64 -Wl,-rpath=/usr/intel/pkgs/perl/5.14.1/lib64 -fno-strict-aliasing -pipe -fstack-protector -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' cf_by='usrintel' - Angan Show quoted text

Because you destroy the integrity of the data structure of the packed executable. You must not modify it in any way. Cheers, Roderich

Read "Anatomy of a Self-Contained PAR executable" in PAR/Tutorial.pod. BTW, rt.cpan.org is a *bug tracker*, not a help forum or a discussion list. Please keep this to actual bugs. For all other purposes, use the mailing list par@perl.org Cheers, Roderich
No more follow up by submitter, closing this bug. Cheers, Roderich
