<span style="font-size:14px">Hello,</span><br>
<span style="font-size:14px">Recently I try to install PETSc with Cygwin since I'd like to use PETSc with Visual Studio on Windows10 plateform.For the sake of clarity, I firstly list the softwares/packages used below:</span><br>
<span style="font-size:14px">1. PETSc: version 3.14.1</span><br>
<span style="font-size:14px">2. VS: version 2022 </span><br>
<span style="font-size:14px">3. MS MPI: download <span>Microsoft MPI v10.1.2</span></span><br>
<span style="font-size:14px">4. Cygwin</span></div></div></blockquote><div><br></div><div>Quick question: Have you considered installing on WSL? I have had much better luck with that on Windows.</div><div><br></div><div>This seems to be an incompatibility of ParMetis Windows support and your version:</div><div><br></div><div>
