[petsc-users] Install PETSc with option `--with-shared-libraries=1` failed on MacOS

[Zongze Yang]

Thank you for providing the instructions. I try the first option.

Now, the error of the configuration is related to OpenBLAS.
Add `--CFLAGS=-Wno-int-conversion` to configure command resolve this. Should this be reported to OpenBLAS? Or need to fix the configure in petsc?

The configure.log is attached. The errors are show below:
