Hi,
I've just installed Visual Studio 2005 (VC++ 8) on my Vista 64 box,
expecting it to be a 64-bit compiler. But I find that sizeof(unsigned long)
is 4 bytes. Where did I screw up ?
(I actually downloaded, installed, and registered "Visual C++ 2005" from:
[url]http://msdn.microsoft.com/vstudio/express/downloads/default.aspx[/url] )
Cheers,
Rob

That's normal. The 64 bit compiler uses 32 bit ints. See...

Aaah ... thanks for the link, Scott.
Cheers,

An additional question re this compiler:
I can't find 'windows.h'. Is there something else I need to download ?
Or does 'windows.h' simply no longer exist ?

Hah! Without windows.h you can't make a window. What you have to do is
install the SDK. If you don't have it on CD you can get it or download
it here:

Heh ... it was my original intention to download and install precisely that.
But none of the links were working, so I decided to give VC 8 a try in the
meantime :-)
I've since managed to download and install that SDK - and I find that VC 8
can indeed make use of the additional includes and libraries that it
contains (by setting INCLUDE and LIB environment variables appropriately).
Of course, the SDK is also a compiler in its own right - so it's doubtful
that I'll need VC 8, anyway (but I'll keep it just in case I do).
Thanks for the help, Scott.
At last I'm starting to feel like I'm getting somewhere. Vista 64 (and
probably also Vista 32) breaks MinGW. I do have a patched version of MinGW's
gcc-3.4.5 (provided by one of the MinGW developers) which works, but I still
don't have a functional g++ or g77. Neither VC 6 nor VC 7 will install (onto
Vista 64) from my disks. It has been a bit of a battle ....
Cheers,
Rob
