Everyting's still broke, but it is likely not because of the fixes (which the fixes you sent do work). I think the problem is compatibility with the platform sdk's linker. Unfortunately you cannot use the XP x64 build environment (aka you can't use VC's x64 build enviroment) in Vista x64 driver development because the Vista driver model requires everything to run in user-mode and building in an XP environment will result in kernel mode component compilations. Also, I rebuild the 32-bit library using the 3.8.2 (for consistency) and found that that library was also corrupt when built under the Platform SDK.

I did however resolve my problem through a very brute-force method of copying the source files needed for win32 compilation to my project directory. If it's successful on Vista 64, I'll be sure to let the mailing list know.

Thanks again for your time and help!

unresolved external symbols.

Our build system is quite different so it wouldn't help you. Anyhow, so I became interested and tried compiling 3.8.2. Here's what I did:

Commented out the #define's in tiffconf.h for PIXARLOG_SUPPORT, ZIP_SUPPORT, and JPEG SUPPORT.

From the Start menu, chose Visual Studio 2005 x64 Win64 Command Prompt

cd to the tiff-3.8.2 directory

nmake -f Makefile.vc

This now creates the libtiff.lib file inside the libtiff directory.

For testing, I just cd into libtiff and put the example file source file from the website, http://www.remotesensing.org/libtiff/libtiff.html#tiffrgbaimage (calling it example.c). Commented out the "...process raster data..." section.

Now test compile (in the shell):

cl /Ox /GX /MD example.c /link libtiff.lib

This all compiled and seemed to run fine when I ran it with a test image. Of course, I didn't verify the actual data read. :)
