[Insight-users] using vcf2c.lib

[Luis Ibanez]

Hi Jeffrey,


The first block of error messages that you are getting
is due to a mix of compilation options in your code.

Some of your code seems to be compiled with the
"Debug Multithread DLL" option, while other parts
seems to be compiled with the option "Single Threaded".
Each one of these compiling option requires to link
with a particular set of libraries. VC++ is now trying
to satisfy both demands but they are conflicting.


You can verify this from Visual Studio on the menu
option :

  Project -> Settings -> C/C++ -> CodeGeneration

ITK use by default : "Debug Multithreaded DLL", so
probably some of the code that you are adding should
be using the other option.

In practice, the best way to make sure that all your
code is consistant is to avoid to create the project
by hand and use CMake instead.  CMake will generate
.dsw, .dsp file on windows and makefiles on Unix that
are consistent with the whole configuration you have.

The secon block of errors is due to a missing library
in your link options.

If you want to create a new project it may be a good
idea to start from the example in :

          Insight/Examples/SampleProject

a CMakeLists.txt file is provided there. You may want
to start from this one and modify it to fit your
settings.

Please let us know if you encounter any problems
setting up your CMakeLists.txt file.



   Thanks

    Luis
