I’ve compiled PETSc ( `--with-scalar-type=complex --with-petsc4py --download-mpi4py` ) as well as dolfinx c++ library.
I tried now to compile the python API however I get an error:
```auto
[92%] Building CXX object CMakeFiles/cpp.dir/dolfinx/wrappers/refinement.cpp.o
In file included from /home/manuel/petsc/arch-linux-c-debug/lib/petsc4py/include/petsc4py/../../PETSc_api.h:9,

```
(so close, 92% … 😢 )
By the way, I also get the message:
```auto

Requirements should be satisfied by a PEP 517 installer.
If you are using pip, you can try `pip install --use-pep517`.

```
I don’t really know which kind of system information can I supply so it’s easier for someone to help me. Thank you very much!!
PS:
I was using the `main` branch from `dolfinx` and the `release` branch from `PETSc`. I tested now with the `main` branch from `PETSc` and the installation breaks earlier, not being able to compile the c++ dolfinx library.
