PAR compilation of custom perl script fails during run

[winksmith]

I have a perl script 4500 line script that i want to compile into a single executable on ubuntu 12.04 system. this will allow it to be run in a configured environment quite easily (e.g. the correct modules are loaded, etc.).

the compilation completes without error, but when i go to run the resulting executable it runs for a while, but as soon as it gets to doing its SOAP HTTPS calls it fails as follows:

I've tried various --module and --link flags, but no luck. i focused around the Crypt::SSLeay, LWP, Net:HTTP, Net::SSL, libssl.so.0.9.8 objects.

My google-foo has let me down this time. Anyone seen this before and/or can give some guidance as to how to make this work?

Did you use -x option?

How about increasing debugging level? Because "read failed" doesn't say why it failed -- the why is the important part

[winksmith]

i didn't see any debugging level specifiable on 'pp'. i had -c, but not -x. when you mentioned it, i tried, but there was no difference. it seemed like a lot of detailed output and related to SSL and/or dynamic loading in LWP. I found a reasonable solution after reading the next reply. see below.

So you think Test::SOAP::connect: read failed is an error message that comes from pp?

See PAR::Environment for debugging PAR

but not -x. when you mentioned it, i tried, but there was no difference. it seemed like a lot of detailed output and related to SSL and/or dynamic loading in LWP. I found a reasonable solution after reading the next reply. see below.

When you used -x did your program attempt to load a https website?

Thats the thing with on-demand plugins, unless you demand them, they're not loaded :)

The long answer can be found at Re: Again with PAR::Packer troubles. The followup has the answer you seek. Full disclosure: I've hit a very similar problem before.

[winksmith]

that was a helpful post. though it didn't exactly hit the spot it suggested setting debug99 for IO::Socket::SSL. once i did this, all errors went away! my next step was to remove the debug flag and magically everything was fine. so, my top level .pl script, even though it doesn't use IO::Socket::SSL directly, benefits from calling it at the top level. i've simplified my pp line quite a bit and everything seems much better. thanks.
