INSTALLATION ON THE WIN64 PLATFORM
|
||
|
|
----------------------------------
|
||
|
|
|
||
|
|
Caveat lector
|
||
|
|
-------------
|
||
|
|
|
||
|
|
As of moment of this writing Win64 support is classified "initial"
|
||
|
|
for the following reasons.
|
||
|
|
|
||
|
|
- No assembler modules are engaged upon initial 0.9.8 release.
|
||
|
|
- API might change within 0.9.8 life-span, *but* in a manner which
|
||
|
|
doesn't break backward binary compatibility. Or in other words,
|
||
|
|
application programs compiled with initial 0.9.8 headers will
|
||
|
|
be expected to work with future minor release .DLL without need
|
||
|
|
to re-compile, even if future minor release features modified API.
|
||
|
|
- Above mentioned API modifications have everything to do with
|
||
|
|
elimination of a number of limitations, which are normally
|
||
|
|
considered inherent to 32-bit platforms. Which in turn is why they
|
||
|
|
are treated as limitations on 64-bit platform such as Win64:-)
|
||
|
|
The current list comprises [but not necessarily limited to]:
|
||
|
|
|
||
|
|
- null-terminated strings may not be longer than 2G-1 bytes,
|
||
|
|
longer strings are treated as zero-length;
|
||
|
|
- dynamically and *internally* allocated chunks can't be larger
|
||
|
|
than 2G-1 bytes;
|
||
|
|
- inability to encrypt/decrypt chunks of data larger than 4GB
|
||
|
|
[it's possibly to *hash* chunks of arbitrary size through];
|
||
|
|
|
||
|
|
Neither of these is actually big deal and hardly encountered
|
||
|
|
in real-life applications.

||

Compiling procedure
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
You will need Perl. You can run under Cygwin or you can download
|
||
|
|
ActiveState Perl from http://www.activestate.com/ActivePerl.
|
||
|
|
|
||
|
|
You will need Microsoft Platform SDK, available for download at
|
||
|
|
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/. As per
|
||
|
|
April 2005 Platform SDK is equipped with Win64 compilers, as well
|
||
|
|
as assemblers, but it might change in the future.
|
||
|
|
|
||
|
|
To build for Win64/x64:
|
||
|
|
|
||
|
|
> perl Configure VC-WIN64A
|
||
|
|
> ms\do_win64a
|
||
|
|
> nmake -f ms\ntdll.mak
|
||
|
|
> cd out32dll
|
||
|
|
> ..\ms\test
|
||
|
|
|
||
|
|
To build for Win64/IA64:
|
||
|
|
|
||
|
|
> perl Configure VC-WIN64I
|
||
|
|
> ms\do_win64i
|
||
|
|
> nmake -f ms\ntdll.mak
|
||
|
|
> cd out32dll
|
||
|
|
> ..\ms\test
|
||
|
|
|
||
|
|
Naturally test-suite itself has to be executed on the target platform.

Installation
