Conflicting Eigen namespaces

Hi all,
I updated today my OpenGeoSys development version (for coupling with the
GEMS4R -> Reaktoro chemical solver) to the latest trunk version. It
looks like there are some changes in the way the Eigen library is used
in OGS. In any case, I have now after the upgrade a conflict in Eigen
namespaces. Rektoro, which is linked as external library, is linked
against Eigen and the header files point to one version of the Eigen
library downloaded/installed during compilation of GEMS4R/Reaktoro. OGS
has now its own - probably modified - version of Eigen in the Thirdparty
directory. Of course the two different versions give different errors
during compilation, depending which of the Eigen libraries is referenced
first via include/header files.

So the answer to the C++/developer/cmake cracks: Is there a way we can
resolve this? I guess the clean solution would be, if I can compile both
software packages against the same external version of Eigen, or?
As Reaktoro already downloads an up-to-date version of Eigen, I would
like to compile OGS against this version or a version available in
standard directories on my linux box!
CU, Georg

Dear Georg,

I'm certainly not the cmake geek here, but my best shot would be the following: you'll have to compile the latest version of eigen first, then link these to your Reaktoro code, which afterwards is included as a library during compilation of OGS, which again uses the firstly compiled eigen library.

Therefore, the question is rather to you, if you have a cmake file for Reaktoro, which you can include into the OGS cmake setup? If yes, you could easily specify one unique eigen lib.

Lars can certainly correct me or give more detailed advice.

Cheers,
Marc

Hi Georg,

Eigen (3.0.7) is included since https://svn.ufz.de/ogs/changeset/13664

I had a look on Reaktoro too. The problem is that neither OGS nor Reaktoro provide a way to use an external eigen library (e.g. via find_package()). As a quick solution you can try to replace the contents of the ThirdParty/Eigen-folder with the recent version (3.2.5) from Reaktoro (see https://github.com/bilke/ogs5/tree/eigen-3.2.5). At least it builds out of the box.

Best,
Lars

Hi Lars,
thanks! That is what I think I will do as workaround :wink:
But on the long term one should think on changing this (in both packages).

Marc, strangely Google thought your email could be spam and stopped it. They informed it to me today because I am a moderator of the mailing list. I added your email address to the white list so you email will never be held from now.
