When I try to install waves2foam on OpenFOAMv1906, there is an error message:

postProcessing/postProcessingWaves/spectralAnalysis/spectralMethods/complexExp.C:31:15: error: redefinition of ‘Foam::complex Foam::exp(const Foam::complex&)’

Does anyone know what the problem is and how to fix it? Thanks!

Hi,

You cannot have two definitions of the same function. It seems the new OpenFOAM version added new functions for complex type objects which already exist in waves2foam.

Is it possible to modify waves2foam to remove Foam::complex exp() thereat?

In new version of waves2foam, there might be refactoring in their code, so that this duplication can be removed. Is it possible for you to issue a bug ticket in waves2foam?

Hi,

Thank you for your reply! I understand that the error was coming from the redefinition of an existing function in the new version of OpenFOAM.

I have checked the waves2foam website on OpenFOAMWiki (https://openfoamwiki.net/index.php/Contrib/waves2Foam) and found in the source code history that even the newest version of waves2foam has not been compatible with OpenFOAMv1906 yet. So it is reasonable that such error occurs. Now I have turned to an older version of OpenFOAM and the installation of waves2foam went well.

Thanks,
