Hi everybody!


I recently installed the latest version of Fedora (30) (I was using Fedora 29 until a few days ago), and started having trouble with OpenFOAM (version 6). It's actually working, but anytime I try to compile a solver (even when it's one of the default solvers) an error happens, which I haven't seen until now, and my research on google has not yielded similar errors to other people. I tried recompiling OpenFOAM. The process goes ok, but again when trying to compile a solver, it crashes. I downloaded OpenFOAM-v1812 to see if that way I could circumvent the issue, but nothing's changed. I attach the message I receive when typing "wmake".
I suppose there's a compatibility problem with any of the new features of Fedora 30, but I wanted to hear from anybody who might have experienced this.


Thank you!
J.A.

Hi,

If we omit warnings, the error is:

In file included from myXiFoam.C:101:
myBEqn.H: In function ‘int main(int, char**)’:
myBEqn.H:20:46: error: ‘small’ was not declared in this scope
   20 |        /((b*c)().weightedAverage(mesh.V()) + small)
      |                                              ^~~~~

Is small constant really declared? Since it is myXiFoam.C I am not able to look into sources to check.

Hi Alexey,


Thanks for your answer. You're right, the error popping up with that solver was due to the fact that OpenFOAMv-1812 does not define a "small" variable like OpenFOAM-6 does. Besides that, I think I got confused with all of the warnings thrown by the compiler, which had not shown before updating to the new version of Fedora. But looking closely, there are not errors between the warnings (aside the one you pointed to) so I can compile them just fine.


Thanks for your time!
Joaquín

Hi!


You have SMALL instead of small.
