Hi All,
I would appreciate if you could give some advice for setting the ‘FormFunction’
for the MatFDColoringSetFunction function call.
I follow what is shown in the example:
https://petsc.org/release/src/snes/tutorials/ex14.c.html
I setup similar code structure like:
PetscErrorCode FormFunction(SNES,Vec,Vec,void*);
Then use it as:
MatFDColoringSetFunction(fdcoloring, (PetscErrorCode(*)(void))SNESFormFunction,
this);
This works fine on my local MacOS. However, when commit it to a remote repo,
the compiler there gives me the following error (where warnings are treated as
errors):
src/base/PETScProblemInterface.C:100:67: error:
cast between incompatible function types from
'PetscErrorCode (*)(SNES, Vec, Vec, void*)' {aka 'int (*)(_p_SNES*, _p_Vec*,
_p_Vec*, void*)'}
to
'PetscErrorCode (*)()' {aka 'int (*)()'} [-Werror=cast-function-type]
Any help is appreciated.
