[vtkusers] error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup

[Jon Haitz Legarreta]

AFAIK, you should compile the sources first in order to get them
used/installed elsewhere. That is, the instructions there say that you
should directly build the INSTALL project, which I have not used myself.

But AFAIK, the INSTALL project just copies the headers and compiled
libraries to a given location when you do not want to have access to the
source files from that other location. And in order to produce the
libraries (whether they are linked as static (*.lib in Windows) or dynamic
(*.dll in Windows), you should first build all core projects.

Now, may be if VTK sees that the sources are not compiled when you compile
INSTALL, it compiles them first. I am not sure about this.

There are a couple of linker issues outlined on that page as well. Check
that you actually have the necessary libraries built and that the test or
example you are trying to run knows where they lie.

VTK's CMakeLists should do that for you if you are running its built-in
examples.

You may also check some compatibility issues between the VTK version you
are using and your compiler.

HTH.
