I've never ever built or test petsc4py under Cygwin. The errors you see are expected. Perhaps you can manually workaround the issues following the following steps: 1) Download the petsc4py tarball and unpack it. 2) Open the file "src/libpetsc4py/libpetsc4py.h", add remove all occurences of DL_IMPORT, i.e, replace DL_IMPORT(XYZ) for just XYZ 3) Use pip again: pip install petsc pip install . The last line assumes your current working directory is the one having petsc4py's setup.py Finally, I do not guarantee this will work. I'm just guessing, petsc4py never explicitly supported Windows and/or Cygwin. -- Lisandro Dalcin ============ Research Scientist Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Numerical Porous Media Center (NumPor) King Abdullah University of Science and Technology (KAUST) http://numpor.kaust.edu.sa/ 4700 King Abdullah University of Science and Technology al-Khawarizmi Bldg (Bldg 1), Office # 4332 Thuwal 23955-6900, Kingdom of Saudi Arabia http://www.kaust.edu.sa Office Phone: +966 12 808-0459
