Original name of a PAR-Packed shared object file?

ek15 has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I am seeing the below error when trying to run an executable that I packed with PAR Packer (pp). How can I find out the original name of the shared object file b1934410.so? I'm trying to get more clues as to why this error is coming up. Thanks.

Hi, boot_IO means the original filename was IO.so on linux. On windows it would be IO.dll... I cant remember, but maybe setting https://metacpan.org/pod/PAR%3A%3AEnvironment#PAR_GLOBAL_DEBUG mentions the original filename What command did you use for packing?	[reply]

I was able to verify that b1934410.so is in fact perl5/auto/IO/IO.so. Now I'm wondering why it would succeed on the build system, but fail on another system. The pp command is below. `pp -c -F Crypto -f Crypto -M Filter::Crypto::Decrypt -l /lib64/libcrypto.so.6 [various libs included] -o bin/switchscan switchscan.pl [various modules included]`	[reply] [d/l]

Hi, Does adding `-x` switch change anything?	[reply] [d/l]
