Ruediger,
I would suggest you fetch the latest libtiff distribution off
www.libtiff.org, which is 3.5.2. This includes simple makefiles for
Windows and MS VC++.
To build libtiff.lib, and libtiff.dll type the following in libtiff\libtiff:
makefile /f makefile.vc all
To build the example programs type the following in libtiff\tools:
makefile /f makefile.vc
My default the libtiff/libtiff/makefile.vc file is building in console
mode, that is libtiff errors are redirected to stderr. If you want them
to appear in popup windows, recompile with WINMODE set to
-DTIF_PLATFORM_WINDOWED in the makefile (near top).
Let me know if you have problems with this process. I do hope to fix up
the build documentation for windows in an upcoming release, but for now
I would appreciate feedback on the mechanism.
Once the above is complete you would compile you program ensuring that the
"-IC:\libtiff\libtiff" or something similar is specified to find the
include files, and that you link against C:\libtiff\libtiff\libtiff.lib.
If you wish to use the DLL, link against the libtiff_i.lib stub library.
Best regards,
