Hi Mark,

I finally got the zlib+jpeg+libtiff combo to play happily in Microsoft-land with a strange mix of a VC IDE project file for jpeg (never got the command line compile to work right), and command line compiles of libtiff and zlib. I can send these to you if you like, but they do include some compiler switches that require either VC7 or the 2003 optimizing compiler download from microsoft--it's free if you have VC6. Please contact me directly if you want the files and more details.

Yeah, I am getting the drift of what Larry, Jeff and Edward are saying. I am trying different things along those lines, including adding the /MDd to "makefile.vc" and to the command line link options in Codewarrior.

And I don't set the flag for JPEG_SUPPORT, so it only creates binaries for libtiff.dll and libtiff.lib, and my program only requires the libtiff.dll now.

But still no luck. Same error:

"Invalid Address specified to RtlFreeHeap"

I will check out the light reading at the msdn weblink that Jeff gave me and try to get better insight into this peculiar problem.

Yeah, like Jeff said.

I've run into similar strangeness. If you are linking zlib and jpeg you should also compile those with the same static or multithreaded options or you can run into problems.

Check to make sure your program and libtiff were compiled

I was able to compile a binary lib and dll using "nmake" (begrudgingly), which is a MS Visual Studio utility (I have it, but don't use much).

I read comments in "makefile.vc" in the libtiff distribution which said to execute

nmake /f makefile.vc all

and that worked to supply me with natively compiled libtiff.lib and libtiff.dll.

Linking them into my program using Codewarrior IDE, I am

Since I am using two different linking environments,

MSVC, I am thinking that the problem lies there.

Anyway, thanks to Edward L. for the new direction.

I'll work with Cygwin gcc and make and let you know how it goes. Gotta install Cygwin first though.

I really recommend setting up make. There's a win32 version of make that you can compile as well although I'm not sure how well it works. We're using the cygwin version of gnu make.
