Don't use PerlApp; therefore, don't know if this is relevant, but since your messages include a reference to the --add command
warn: auto\File\Spec\Unix\Unix.dll not found
refby: perlapp --add
from the AS doc re PerlApp9.3 here's some possibly relevant information:
List additional modules to include in the application. PerlApp also attempts to include
modules that the listed modules depend on. Multiple modules can be separated by whitespace
or a semicolon. This option can be repeated. For example:
perlapp myscript.pl --add IO::Socket --add XML::Parser::Expat
...would include IO::Socket and XML::Parser in your application.
The --add option supports the following wildcard notations: --add Module::* includes Module::Foo,
but neither Module itself nor Module::Foo::Bar. --add Module::** includes Module::Foo and
Module::Foo::Bar, but not Module. --add Module:: works the same as --add Module;Module::**,
including all of Module, Module::Foo and Module::Foo::Bar. Note that you may have to quote
the * character to prevent wildcard expansion by your command shell.
PerlApp uses built-in heuristics to determine any additional modules that may be required at
runtime. When building an executable, missing modules are displayed as errors. In a few cases,
however, the heuristics are used to downgrade errors to warnings. PerlApp issues warnings
for the following:
+ Windows executables built without Unix, Mac, VMS and OS/2 modules
A bit more information about your script and source might win you better help from those more knowledgable of PerlApp than I.
