Since any comments are welcome -- why are you using Microsoft on a production server? In this day and age I just can't wrap my head around not using open source. I mean ... we use Linux servers and NEVER have these issues. EVER. Plus, it's so cheap it's almost free. YMMV. jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply]

Jeffa, Many of our production servers are migrating across to Linux, and believe me when i say i would love to migrate these app servers aswell... Unfortunately the App in question currently only supports Windows, through a combination of requiring Java 1.4 and a propitiatory, currently Windows only DLL for smart-card readers... Yes, i know i know... There is development scheduled to migrate to Linux, but it's a way of yet, so currently have to make do with Windows... Cheers for the comment though... Anyone else? Cheers Gavin	[reply]

You need to link with the same version of Perl DLLs and the same version of the C run-time library, and that means doing that on a 64-bit machine with Microsoft Visual Studio. I expect (though I am not certain) that for the Oracle DBD you will need the Oracle DLLs as well.	[reply]

If you're determined to go down the M$/AS route, IMO you'll have to (get your employer to) invest in M$ VisualC++, install it on the target platform and hope that nmake etc. will understand all of the make(1) script generated by `perl Makefile.PL` when you run the standard CPAN `perl Makefile.PL, make install` sequence.

Of course, Perl by grace of ExtUtils::MakeMaker tries to do the Right Thing, because ExtUTils::MakeMaker outputs `nmake` syntax when it sees that the current Perl uses `nmake` as its `make` tool.	[reply] [d/l] [select]

That is undoubtedly true Corion ... and many more ++ to the authors & maintainers of said module. My point was that my, mostly infuriating, experience(s) attempting to build perl modules using M$ under Windoze suggest that... Adopting Strawberry perl, or similar or ... Making a design decision, at the outset, to use only pure perl modules both offer a path of far less resistance, tho' self-evidently, the latter is far more constraining - almost masochistically so;-) A user level that continues to overstate my experience :-))	[reply]

Ok, i've had a read of the MakeFile.pl for Win32-SystemInfo, and it lists Win32::API as a requirement... Am i right in thinking i'm stuck as i cant use Win32::API on a 64Bit box??? Comments??? Cheers Gavin	[reply]

If you don't have VC (cl.exe) on your PATH, but have MingW and dmake installed, then ActivePerl will automatically use them to builds XS code. `perl Makefile.PL` will automatically generate the correct `Makefile`, not configuration is required beyond putting MinGW and dmake on the PATH.

Ok, lets try and go a different way about this then? Does anybody know a way i can get Perl to read the Total/In Use RAM Counters on a 64Bit Windows Server 2k3 with 8Gb+ Ram??? Cheers Gavin	[reply]

Does anybody know a way i can get Perl to read the Total/In Use RAM Counters on a 64Bit Windows Server 2k3 with 8Gb+ Ram??? If you know of a Windows API function that returns the values you want, then you could access that function from perl using XS or Inline::C. Obviously, on a 32-bit perl, such an XSub could not return a 'uv' (long) value, as 'uvs' aren't guaranteed to be large enough to store the value being returned. But you could have the XSub return the value to perl as an 'nv' (double) or a 'pv' (string). On your 64-bit perl, the XSub could simply return the value as a 'uv' (since it uses 64-bit uvs). I would expect that such a Windows API function does exist ... presumably the modules in question are accessing that Windows API function with Win32::API. Do you know which Windows API function(s) you need to access ? Cheers, Rob	[reply]

Rob, I was trying to use win32::SystemInfo, so dont know if you can pick the info out of that??? Source code is here: http://search.cpan.org/src/CJOHNSTON/Win32-SystemInfo-0.10/SystemInfo.pm Any ideas? Cheers Gavin	[reply]

Not knowing much and caring less, about Windoze, would parsing output from the `perfmon` command (if it exists on your host) be any use ?? Maybe it has a command mode that reports memory only ... or might that be a bit too useful ;-) I don't have a Windoze m/c on which to try it ...
