[petsc-users] petsc4py Build Problem

Hello, I am trying to build petsc4py-3.5.1 using Cygwin on 64-bit Windows 7. I have built PETSc 3.5.4 with shared and dynamic libraries using mpich2-1.2.1 and successfully ran the installation tests. I am using Python 2.7 and NumPy 1.9.2 and have installed mpi4py. However, when I attempt to install petsc4py (both with pip and distutils) I get a mpicc compiler error due to undefined references/symbols. I have attached the output of running pip install petsc petsc4py --allow-external petsc --allow-external petsc4py Thank you in advance for any help, Mikhail Khodak
