Failure Summary

Digest
*build stage failed for Digest: Failed building lib\Digest\SHA.pm

Its the use of σ in lines 94, to 97 on a Windows 8 box

        my $σ0 = [+^] map { rotr @h[0], $_ }, 2, 13, 22;
        my $σ1 = [+^] map { rotr @h[4], $_ }, 6, 11, 25;
        my $t1 = [⊕] @h[7], $σ1, $ch, $K[$j], @w[$j];
        my $t2 = $σ0 ⊕ $maj;

Changed to o $o0 and $o1 from $σ0 and $σ1 and it compiles without issue.

Can't reproduce this on Linux MoarVM. Not sure what to do about it : it's not specific to the library but appears to be a rakudo bug. I suggest trying to find a minimal code reproducing the error and post it at rakudobug@perl.org

What does the following line does?

perl6 --target=mbc --output=test.mbc -e 'my $σ = rand;'

[nsharrok]

my $σ0;

This reproduces the error on windows 8

Please run 'perl6 --version'

This all works fine for me on windows 7 on jvm:

My JVM reports fail, but thats on both linux and windows. However, the examples posted here worked fine. http://testers.p6c.org/reports/35205.html

parrot is not a supported backend for now, so you may want to try a newer distro

[FROGGS]

I'd recommend http://rakudo.org/downloads/star/rakudo-star-2015.02.msi on Windows until the 2015.03 will be available, which will happen in a week or two.

http://rakudo.org/downloads/star/rakudo-star-2015.02.msi is the the distro
I am using

http://rakudo.org/downloads/star/rakudo-star-2015.02.msi does not include the parrot backend (we can determine the backend being used by

I just installed that .msi myself and it did not install parrot. You may have an old rakudo install in your PATH.

Or depending on how the .msi works, the installer might be defaulting to parrot if its already installed even though its not currently supported (since it would bypasses the Configure.pl parrot support message). What does perl6 -v say? What are the contents of the perl6.bat file? Do you have a moar.exe?

Hi Ugexe,
You are correct. I must not have uninstalled the old version o fPerl6
before installing the latest.
C:\Users\nsharrok\Documents>perl6 -v
This is perl6 version 2014.12 built on parrot 6.10.0 revision 0

install the new
C:\Users\nsharrok\Documents>perl6 -v
This is perl6 version 2015.02 built on MoarVM version 2015.02

No wonder I was having such a problem with all sorts of bits and pieces

Thanks
Noel
