Hi,

No my Win64 VM I have FPC 2.6.2 and 2.6.4 installed using the official FPC installers. For example: fpc-2.6.4.x86_64-win64.exe

I wanted to upgrade my VM to FPC 3.0.0, but I don't seem to find an official Win64 release like prior versions. All I can find as a what I assume is a 32-bit cross-complier to win64:

fpc-3.0.0.i386-win32.cross.x86_64-win64.exe

Why did FPC stop making official native win64 compilers? Or is this just a naming convension change?

ps:
How do I know if a program (executable) is 32-bit or 64-bit under Windows? Using Unix-like OSes, I can simply use the "file" command. What is the equivalent under Windows?

ps #2:
Why doesn't the Free Pascal SourceForge page contain a "Win64" folder. The prior FPC releases, the native 64-bit installations are filed under the "Win32" folder. This seems a bit confusing.

The windows team doesn't think there are sufficient reasons/arguments for a 64-bit native compiler.

(So, I roll my own. Luckily, this is not that hard)

Right-click in explorer, 'Properties', and then 'details' or so ?

See above.

Lazy buggers! ;-)

I'll do the same, thanks.

Nope, that's the firs place I looked. I've got 64-bit Windows 7 installed. The "Properties -> Details" dialog list the file type, version, copyright etc... but nowhere does it say 32-bit or 64-bit.

I can see the "*32" in the Windows Task Manager which indicates 32-bit or 64-bit applications. But that is only useful for long running apps.For very fast running applications (eg: many console utilities) it appears and disappears to quickly for me to see.

you can use file ;)

or PE Explorer iirc even some objdump builds (maybe even the ones that come with FPC)

It's a naming change: the previous Win64 releases were also cross-compilers. There is no advantage I'm a aware of to having a "native" Win64 release compiler, and there are disadvantages such as the inability to compile for any other x86-64 target (because the x87 fpu is deprecated for 64 bit on Windows).

I have the installs (with unintall support) for 2.6.0 & 2.6.2 on my system, and they are both native Win64 compilers. I believe they are official installers. The 2.6.4 and 3.0.0 installers on SF.net are definitely cross-compilers.

No matter, like Michael said, it is quite easy to build your own, which I did.

Well, at the moment you need to do two downloads & installs to get Win64 support. First you need to install the win32 compiler, then the win64 cross-compiler. But yes, I guess that is minor - how often does one install release compilers anyway. ;-)

Thanks for the info though.

I checked again, and you were on the right track. The easiest way, without installing another program or running the GNU "file" command, is just to right click on the file, choose Properties, and then go the the Compatibility tab. If there are no greyed out options and Windows XP and 9x modes are offered, it's 32-bit. If there are greyed out options and Vista is the earliest mode offered, it's 64-bit.
