Error within the Rheology Framework

1

Hello Brad,

Work is continuing with the poroelastic branch (https://github.com/josimarsilva/pylith/tree/poroelastic), and @josimar and I are having a bit of an issue with a compiled build, producing the following demangled error when pylith is run without command line options or a .cfg file:

   Traceback (most recent call last):

ImportError: /home/dockimble/build/pylith/lib/libpylith.so.0: undefined symbol: pylith::materials::RheologyPoroelasticity::getKernelRHSJacobianBiotCoefficient(spatialdata::geocoords::CoordSys const*) const

Try as I might, I cannot find where this undefined symbol could be; aside from the rheology framework(_rheology->getKernelRHSJacobianBiotCoefficient(coordsys):wink: the offending function is not listed in the manner described.

Any help would be greatly appreciated.

Thank you,
Robert

Never mind, I think I got this one, the problem seemed to be remedied by setting all trailing const = 0 in the RheologyPoroelasticity.hh file.
