[petsc-users] error of compiling complex

[Satish Balay]

Something wrong with your build. This source-file should not get compiled for complex.

And this relative path looks wierd. How are you building PETSc?

Might start with a fresh petsc install. [and look at updating to latest release - petsc-3.13]

And send complete build logs - if you still have issues.
