Most likely the Perl "glue" library for Tk::PNG (probably called
.../TK/PNG/PNG.xs.dll)
is linked with the png library (included in Strawberry Perl as
c/bin/libpng16-16__.dl),
but this libpng isn't included in the executable generated by pp.
PAR::Packer doesn't know about dependencies like this and never packs non-Perl
libraries unless explicitly told to do so. In this case
pp --link libpng16-16__.dll ...
should do the trick. You may verify that libpng gets packed by looking at the
output of
unzip -l your.exe
In general, if module Foo::Bar shows this problem, locate its "glue" library
.../Foo/Bar/Bar.xs.dll, then run
objdump -ax ../Foo/Bar/Bar.xs.dll | perl -ne 'print if /DLL Name/'
to show the libraries it is linked with, e.g.
DLL Name: msvcrt.dll
DLL Name: libpng16-16__.dll
DLL Name: KERNEL32.dll
DLL Name: perl524.dll
Ignore Windows system libraries like msvcrt.dll and KERNEL32.dll, also the
Perl shared library perl*.dll. The rest should be specified as --link's
on the pp command line.
