When building Rakudo under Windows, I noticed several warnings "fatal​:
No names found, cannot describe anything." during the make process.
Investigating it closer, it stems from Windows Command.exe CLI being
obstreperous about what quoting it will accept.

In /build/gen_version.pl, the line​:

if (-d '.git' && open(my $GIT, '-|', "git describe --match '2*'")) {

https://github.com/rakudo/rakudo/blob/master/build/gen_version.pl#L17

fails because the Command.exe doesn't like the single quotes around
'2*'. Changing it to​:

if (-d '.git' && open(my $GIT, '-|', "git describe --match \"2*\"")) {

lets it work correctly and shouldn't affect less brain dead terminals
negatively.

Before​:

C​:\Rakudo>C​:\strawberry\perl\bin\perl.exe build\gen_version.pl
# generated by build/gen_version.pl
fatal​: No names found, cannot describe anything.
.macro_const RAKUDO_VERSION ''
.macro_const RAKUDO_BUILD_DATE '2011-01-20T12​:59​:53Z'

C​:\Rakudo>perl6 -v
This is Rakudo Perl 6, version built on parrot 3.0.0 RELEASE_3_0_0

After​:

.macro_const RAKUDO_VERSION '2010.12-47-g13b405c'

C​:\Rakudo>perl6 -v

Thanks for the report.

This file is now here​: parrot/tools/build/gen_version.pl

And no longer has the line referenced above; so any remaining problems are hopefully different. Closing ticket.

If you still have windows build problems with the current build system, please open a new ticket, thanks!
