Use of uninitialized value (Perl)

[maesaar]

The issue is same as stated in #196. Can you explain why I get this message at the end of Roary's run:

Use of uninitialized value in require at /System/Library/Perl/5.18/darwin-thread-multi-2level/Encode.pm line 60.

The error is likely a bug in the perl module itself. It doesn't seem to affect roary results.

The error is in this section - and you can see a bugzilla report about it. I don't think we can fix it.

# Make a %Encoding package variable to allow a certain amount of cheating
our %Encoding;
our %ExtModule;
require Encode::Config;
#  See
#  https://bugzilla.redhat.com/show_bug.cgi?id=435505#c2
#  to find why sig handers inside eval{} are disabled.
eval {
    local $SIG{__DIE__};
    local $SIG{__WARN__};
    require Encode::ConfigLocal;    #### HERE I THINK
};

Oh, that's a relief. It was worrisome since it said error instead of warning! Thanks for the clarification.
I see a similar error too:

Use of uninitialized value in require at /anaconda2/lib/site_perl/5.26.2/darwin-thread-multi-2level/Encode.pm line 61.
Use of uninitialized value in require at (eval 734) line 1.

I encountered this error currently with perl 5.22.1, while it seems to work correctly if I comment out require Encode::ConfigLocal; #### HERE I THINK. Roary's maintainers suggest simply updating perl Encode, but I wasn't able to get that fix to work.

run the command
enc2xs -C
which should create ConfigLocal.pm for you

OMG THANK YOU @trstickland i've been trying to figure out how to resolve that for YEARS.
