Hi, The PAR::Tutorial suggests using upx to reduce exe sizes however this no
longer seems to work:When I run the upx generated executable I get the
following error messages:
IO error: reading header signature :
at -e line 603.

File exists; Cannot create a file when that file already exists at
C:/strawberry/perl/vendor/lib/Archive/Zip/Archive.pm line 196. Note I get
similar errors with older versions of upx so if upx has worked before (as
implied by PAR::Tutorial) the issue might be with "new magic" used by PAR. For
more details see: https://github.com/upx/upx/issues/289

Don't do that then.
I removed this suggestion from PAR::Tutorial.

Hi, I wouldn't have been trying that if PAR-Packer packed better and upx
generated exes weren't half the size of pp exes. BTW upx -d on the upx
compressed pp exe produces an exe that works so upx isn't throwing away data
required to run. Are the "magics" done by pp and upx incompatible in an
unfixable way? 26.07.2019, 19:46, "Roderich Schupp via RT"
