PETSc 3.7.5 error: cannot convert ‘PetscBool’ to ‘PCMGGalerkinType’ in PCMGSetGalerkin(PC, PCMGGalerkinType) #5

Hi,

It seems that there is an issue while compiling with a newer version of PETSc:

/TopOpt_in_PETSc/LinearElasticity.cc:613:32: error: cannot convert ‘PetscBool’ to ‘PCMGGalerkinType’ for argument ‘2’ to ‘PetscErrorCode PCMGSetGalerkin(PC, PCMGGalerkinType)’ PCMGSetGalerkin(pc,PETSC_TRUE);

Hi,

I've just done a check of the framework with PETSc versions 3.7.5 and 3.7.6 - and cannot reproduce the error you have encountered. Also the petsc documentation indicates that the interface to PCMGSetGalerkin() is correct in LinearElasticity. So could you provide more information on your setup, i.e. what platform you use and how did the verification of your PETSc installation state (result of the test after compiling)?

I'm currently utilizing a recent clone from https://bitbucket.org/petsc/petsc in order to achieve cuda acceleration. the config command included: ./configure --download-mpich --with-cuda=1 --with-cusp=1 --with-thrust=1 --with-precision=double --with-clanguage=c Compilation was successful and both test and streams worked at the end of compilation. I apologize for miss-attributing the version number.

I was able to find documentation on the function here: https://www.mcs.anl.gov/petsc/petsc-dev/docs/manualpages/PCMG/PCMGSetGalerkin.html

Thanks for the clarification and thanks for the heads up regarding the change in method interface for the next version of PETSc. I will, however, wait with updating the code until the PETSc developers release a new version officially - but have added a comment in the README file stating the possible issues with using newest git branch. In case you have not already resolved your issue you should use the PCMGGalerkinType to PC_MG_GALERKIN_BOTH.

Has this error been fixed? I am seeing this same error for both LinearElasticity and PDEFilter come up on Ubuntu 18.04 using Petsc-11.4.1. I would greatly appreciate if someone can share how to fix it.
