[Trilinos-Users] Problem running my own example with visual studio 2013

Tue Sep 16 12:09:41 MDT 2014

One more point: the cmake generator in your example should match the

cmake generator for Trilinos.

First, you should try to get rid of the warning perhaps using the suggestion here.

http://www.cmake.org/pipermail/cmake/2014-September/058517.html

Second, make sure TRILINOS_PATH in your cmake call for the example points to the

path to your Trilinos installation and not source code base directory.  And make sure that

installation has include/lib directories and Epetra_SerialComm.h is present there.

If this still leads to the error that Epetra_SerialComm.h is not found,

then check for the include paths in visual studio project properties.

Thanks for your reply. 

When I opened my example project in visual studio I changed the solution platform from Win32 to x64 which got rid of the error,
however this has been replaced with a new error:

2>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppBuild.targets(381,5): warning MSB8028: The intermediate
directory (x64\Debug\) contains files shared from another project (ZERO_CHECK.vcxproj).  This can lead to incorrect clean and
rebuild behavior.

2>  main.cpp

2>main.cpp(43): fatal error C1083: Cannot open include file: 'Epetra_SerialComm.h': No such file or directory

This is probably a really silly error on my part but I'm new to Trilinos and still confused about this. As I mentioned I am just
trying to run a very simplified Epetra example. Here is the code from my main.cpp file:

#include "Epetra_SerialComm.h"

#include "Epetra_Map.h"

#include "Epetra_Vector.h"

#include "Epetra_Version.h"

int main(int argc, char *argv[])

{

  std::cout << Epetra_Version() << std::endl << std::endl;

  Epetra_SerialComm Comm;

  int NumElements = 1000;

  std::cout << "NumElements = " << NumElements << std::endl;

  return 0;

}

Do I need to list the header files Epetra_SerialComm.h, ... ,Epetra_Version.h in the sources part of the CMakeLists.txt file? I have
tried doing this and I then get an error that it cannot open include file: Épetra_config.h. 

Here is my do-configure file:

-------------------------------------------------------------------------------------------

cmake \

  -D TRILINOS_PATH:FILEPATH="C:/Trilinos" \

  -D CMAKE_BUILD_TYPE:STRING=DEBUG \

  -D BUILD_SHARED_LIBS:BOOL=OFF \

  -D CMAKE_VERBOSE_MAKEFILE:BOOL=ON \

.

And CMakeLists.txt:

Sorry if I have made a stupid mistake somewhere but I'm finding this very confusing. Any help would be greatly appreciated.
