[Trilinos-Users] newbie, using Trilinos 10.0.4 on Ubuntu 10.0.4

[Day, David]

Dear Monosij,
I too am new to C++. I am not a Trilinos developer.   However I think that the Export_Makefile tools do not work with CMake.
Sincerely,
David Day

Subject: [Trilinos-Users] newbie, using Trilinos 10.0.4 on Ubuntu 10.0.4

I am in my first attempts into getting into Trilinos and also somewhat new to C++, Makefiles and such. However have a strong Java, DB background.

I installed Trilinos from the repository and can get some of the examples to compile using g++ - giving the specific paths to the compiler from the command.

However cannot get the makefiles to run. Specifically I am trying to work with Epetra and am attempting to compile this example:

http://code.google.com/p/trilinos/wiki/EpetraSimpleVector

<http://code.google.com/p/trilinos/wiki/EpetraSimpleVector>with a modification of this makefile.

http://trilinos.sandia.gov/Export_Makefile_example.txt

So in the makefile it is supposed to pick up variables from: Makefile.export.Epetra.
----------
So my questions were:

1. It seems the mpic++ compiler is used, which I have installed. However it gives errors.

2. I can seem to include Makefile.export.Epetra by giving the full path to it as in: /usr/include/trilinos/Makefile.export.Epetra. However if I have /usr/include/trilinos in my PATH and just have Makefile.export.Epetra in the Makefile, it can't seem to find it.

3. Why is the mpic++ compiler being used and not g++.

4. Would it better to try and use CMake from the get go rather than Make? Are there some examples in using CMake to start some basic tutorials with.
----------
So these are likely very basic questions and appreciate your patience - however would appreciate any pointers to them especially specific things I may need to be doing with regards to Ubuntu as I could not find much documentation on it.

Also I am happy to help in this regard as well.

Thanks for your help.
