that the settings are correct (except for creating the and using dlibtiff.lib in the debug mode, just using the libtiff.lib in I?m debug mode).

I am getting the following errors when I try to compile: MSVCRT.lib(MSVCRT.dll): error LNK2005: _strncmp already defined in LIBCMTD.lib(strncmp.obj) MSVCRT.lib(MSVCRT.dll): error LNK2005: _sprintf already defined in LIBCMTD.lib(sprintf.obj)

I have read & search over the mailing list archive and found this post which is same issue that I having (2). I have read the response and understand the reason of the error, but still having trouble figuring out what I need to do to correct it. The tutorial (1) warns of this problem and I have double checked that my settings match. Either the answer is staring me in the face, or it is not there to be found.

My question/help request is can you please point at what specifically needs to be changed so that I will not have this issue?

Phillip,

The way to build libtiff, described in the tutorial you are mentioned is not supported by the developers. Libtiff comes with a set of makefiles and configuration file (nmake.opt) where the build parameters defined. You should edit the line OPTFLAGS. The most important option is /MD. With this option compiler will use dynamically linked multitreaded runtime libraries. If libtiff is built with the /MD option, the other software you want link against libtiff must be built in the same manner.

There is short and incomplete reference how to build libtiff with the MSVC compiler:
