RE: Question regarding perl and perl-libwin32 using the latest cygwin ... and an anomaly

["Rafael Kitover" <caelum at debian dot org>]

Hi Alan,

My apologies for not sending out an announcement about this package, was
waiting for the 1.5.7 stuff to die down a bit first, but I will shortly.

test.pl is not a bash script, and that tries to execute it as one since there's
no #!/usr/bin/perl line at the top. My fault for not using the appropriate
ExtUtils function for installing these, but this is a fairly minor bug so I
will fix it on next package revision, as "perl test.pl" should work
fine...unless of course it doesn't and the problem you're describing below can
be reproduced.

Have you tried just running "perl test.pl"? Works here, this is on a fresh
Cygwin install. I can't seem to reproduce this.

Some questions for you:

Do you have the latest perl package?

When you run "perl -V", is
"/usr/lib/perl5/site_perl/5.8.2/cygwin-thread-multi-64int" at the bottom of the
output, in the @INC array? Is archname set to
"archname=cygwin-thread-multi-64int"?

Does "which perl" give you /bin/perl ?

Does perl -MWin32::OLE -le 'print $Win32::OLE::VERSION' print "0.1502" or does
it give you an error?

It seems that there's something wrong with "localtime" in Perl. I can reproduce
this:

$ echo $TZ
PST8PDT7,M4.1.0/2,M10.5.0/2
$ date
Tue Jan 20 23:10:12 PST 2004
$ perl -MPOSIX=strftime -le 'print strftime("%x %X",gmtime)'
Wed Jan 21 2004 07:10:21
$ perl -MPOSIX=strftime -le 'print strftime("%x %X",localtime)'
Wed Jan 21 2004 07:10:26

However, when I try the newlib "localtime" function, it works fine:

$ cat localtime.c
#include <time.h>
#include <stdio.h>

int main(int argc, char** argv)
{
        char buf[1024];
        time_t cur_time = time(NULL);
        strftime(buf, sizeof(buf), "%x %X\n", localtime(&cur_time));
        printf(buf);
        return 0;
}
$ gcc localtime.c -o try.exe && ./try.exe
