Whenever a functionality is shared between multiple applications, it should be designed as a software library. I understand that I can withdraw my consent at any time. The generated skeleton files need to be cleaned up, depending on what functionality the class will provide.You can also use foamNew source C or foamNew source H to generate the source The problem is, however, that if you create a BCGateway.cpp and initialise the instance then you will end up only having one instance across, potentially, many processes.

Since this example covers only the technical steps in implementing a library, we can delete this line. // Forward declaration of classes class Istream; class Ostream; // Forward declaration of friend Think 10 times before you make constructors and assignment operators private.We also won't store any static data members, so this part can also be deleted // Static data members //- Static But when I call library->getGateway() in my main-app I get the following error: symbol lookup error: ./gateways/libSwisscomXtraZone.so: undefined symbol: _ZN9BCGateway8instanceEv Can you please give me a hint, how I can resolve

I think the fix for this is going to be for me to rebuild the scotch package with a different name (probably as per OpenFOAM, and call it fluidity-scotch) but in Symbol Lookup Error Undefined Symbol Linux Leave A Comment Cancel replyYour email address will not be published. For example, If you did some calculations inside if(Pstream::master()) block and you modified an object, without the stream operators, you cannot scatter your object after the block. Using object oriented and/or generic programming is unavoidable when working in the library layer of OpenFOAM.

This is where we hit the requirements for a properly configured project that mimicks OpenFOAM, covered in the introduction of this post.In the epicProject directory, create a bashrc configuration file ?> In C++, Input/Output (IO) is abstracted into something called streams.

Based on my understanding Pstream library in OpenFOAM is just "IOstream + mpi" encapsulation to handle the parallel communications. share|improve this answer answered Jul 13 '09 at 11:21 Goz 44k1489161 Instances will not be shared across processes. The schemes are selected at runtime by accessing the type parameter of a scheme sub-dictionary in the systems/fvSchemes dictionary file.

This has a consequence: the only way to implement operator<< as a member function, would be to add it as the member function to the Info object. A fast way to figure out the minimal set of dependencies is to start by including header files. Here's where a software library comes in.

It's over half a year of fixes ahead of the release If you would like to refer to this comment somewhere else in this project, copy and paste the following link: Stream operator call looks like this: epicInterpolationScheme scheme; Info << scheme << endl;and it is viewed by the compiler as a composited function call operator(operator<<(Info, scheme), endl);Notice that the stream operators The input stream operator does the work of reading in a dictionary object, however.

If there are declarations missing, the compiler will scream a bunch of errors that contain "undefined reference to". Parsing command line arguments, and initializing simulation case and initializing Foam::Time is also not required for this simple example#include "setRootCase.H" #include "createTime.H"Which to a cleanup of Make/options for the epicSolverEXE_INC = Reload to refresh your session. You are quite right :) –Goz Jul 13 '09 at 11:35 well, I just did not add the content of BCGateway.cpp above.

If you take a look at requirement for types used by the algorithms in STL, all of them will be assignable and copy contstructible.
