We are trying to build 5.20.1 64bit on win7 with VS2010 in our
company, and get errors on building encodings. The error messages were
like in #118261 https://rt.perl.org/Public/Bug/Display.html?id=118261
(note that cl usage issue, but the enc2xs error described at the
beginning of that post. )

We guess the problem is at enc2xs, line 125

eval "\@​ARGV = map(glob(\$_),\@​ARGV)" if ($^O eq 'MSWin32');

And we added some print statements (eg. print "DEBUG before glob​: ",
join(' ', @​ARGV), "\n";) before/after this line to check it. And the
log is like below,

if exist ..\..\..\lib\auto\Encode\Byte\Byte.dll.manifest mt -nologo
-man ifest ..\..\..\lib\auto\Encode\Byte\Byte.dll.manifest

So it turned out that after this glob, it may lose file name in @​ARGV.
(See the two "DEBUG" output above) This issue happens intermittently,
and if you nmake clean and nmake again, it may happen at another place
that relates to enc2xs. And there is a small chance that it could pass
making.

Thanks.

Do you see the same problem if you run glob manually using miniperl?

eg.

  .\miniperl -le "print for glob(shift)" -- -Q,-o,ir_04_t.c,-f,ir_04_t.fnm

Hi Tony,

I tried running it for like 20~30 times. And for two times it got errors.

Thanks.
