Hi, I have a problem with Perl deployment, sorry for the long post but I would like to explain it clearly.
Basically I'm trying to compile XMLTV (which is written in Perl) to run it on my QNAP TS-239 embedded system, which is an x86 architecture.

As I want to distribute XMLTV to others, I want also to be able to compile it for several other QNAP NAS models, which run for example x86_64 or armel but that's a further question.

Let's start with the system information: I'm using the QNAP and a Debian Lenny Virtual Machine.

Using that VM I was able to compile any C code and then - moving those files on the QNAP - they run successfully.

I first tried building the XMLTV on the Debian VM. As I want to deploy the XMLTV application to others, I've built it together with the required modules in a custom folder: /root/out.

I first installed CPAN, changed its configuration data with:

o conf makepl_arg INSTALL_BASE=/root/out
o conf commit

[download]

then I've compiled all the dependecies like LWP and Date::Manip. Sometimes CPAN fails to build a module automatically, like with XML::Parser, so I've used:

look XML::Parser
perl Makefile.PL INSTALL_BASE=/root/out
make && make install
exit

[download]

... obviously by resolving the required dependencies first (which are printed on the console when running perl Makefile.PL).

Finally I've compiled XMLTV too in the folder /root/out/xmltv using the same commands than before; I've exported the PERL5LIB:

export PERL5LIB=/root/out/lib/perl5:/root/out/xmltv/lib/perl5

Then if I run /root/out/xmltv/bin/tv_grab_it on the Debian VM it works OK.

Moving the whole "out" folder inside the QNAP /share/FTP directory, exporting the PERL5LIB (with the corresponding dirs) and running tv_grab_it however gives this error:

# /share/FTP/out/xmltv/bin/tv_grab_it

Actually, the file XML/Parser.pm exists in the folder /share/FTP/out/lib/perl5/i486-linux-gnu-thread-multi; if I try to export that dir also like this:

# export PERL5LIB=/share/FTP/out/lib/perl5:/share/FTP/out/xmltv/lib/pe
+rl5:/share/FTP/out/lib/perl5/i486-linux-gnu-thread-multi

+x-gnu-thread-multi/auto/Storable/Storable.so: undefined symbol: Perl_
+Istack_sp_ptr

It seems that the XS modules cannot be deployed correctly.
I also tried to compile (with the same procedure) XMLTV on the QNAP using CPAN; the funny thing is that then it runs on the QNAP but it fails (with a similar error) on the Debian VM.

So my questions are: is this the correct procedure? How can I compile and deploy XML::Parser and the other Perl modules that require XS, like Storable, on another system?

I want to distribute that libraries on a custom folder and then make Perl load them; I need to build them in a virtual machine because of the other architectures (for example for armel I'm running QEMU with Debian versatile).

Please help me, I'm new to Perl and that has already been difficult for me to reach this point... Thank you, bye.
