Normally, this gets included when __MSC_ is defined instead of stdint.h (in gk_arch.h).

Can you upgrade to the latest? Let us know if this resolves the problem. Barry

Hi Barry

Thanks for your reply.

I check the package parmetis,and the "petsc-pkg-parmetis-45100eac9301.tar.gz" is form https://urldefense.us/v3/__https://bitbucket.org/petsc/pkg-parmetis/get/v4.0... . So I made a mistake about the package.

Then I download the package form https://urldefense.us/v3/__https://bitbucket.org/petsc/pkg-parmetis/get/v4.0... <https://urldefense.us/v3/__https://bitbucket.org/petsc/pkg-parmetis/get/v4.0... >.tar.gz <https://urldefense.us/v3/__https://bitbucket.org/petsc/pkg-parmetis/get/v4.0... > and it is "petsc-pkg-parmetis-f5e3aab04fd5.tar.gz"

Then the compiler option in configuration is: ./configure --with-debugging=0 --with-cc=cl --with-fc=0 --with-cxx=cl --download-f2cblaslapack=/cygdrive/g/mypetsc/f2cblaslapack-3.8.0.q2.tar.gz --with-mpi-include=\[/cygdrive/g/MSmpi/MicrosoftSDKs/Include,/cygdrive/g/MSmpi/MicrosoftSDKs/Include/x64\] --with-mpi-lib=\[/cygdrive/g/MSmpi/MicrosoftSDKs/Lib/x64/msmpifec.lib,/cygdrive/g/MSmpi/MicrosoftSDKs/Lib/x64/msmpi.lib\] --with-mpiexec=/cygdrive/g/MSmpi/MicrosoftMPI/Bin/mpiexec --download-metis=/cygdrive/g/mypetsc/petsc-pkg-metis-69fb26dd0428.tar.gz --download-parmetis=/cygdrive/g/mypetsc/petsc-pkg-parmetis-f5e3aab04fd5.tar.gz --with-strict-petscerrorcode=0 --with-64-bit-indices

but it still have the same error: ********************************************************************************************* ============================================================================================= ============================================================================================= Configuring PARMETIS with CMake; this may take several minutes ============================================================================================= ============================================================================================= Compiling and installing PARMETIS; this may take several minutes =============================================================================================

********************************************************************************************* UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): --------------------------------------------------------------------------------------------- Error running make on PARMETIS

*********************************************************************************************

The new configure.log is attached below.

So I ask for your help again.

Looking forward your reply!

Where/how did you obtain /cygdrive/g/mypetsc/petsc-pkg-parmetis-45100eac9301.tar.gz ? Was it from PETSc ./configure?

self.version = '4.0.3' self.versionname = 'PARMETIS_MAJOR_VERSION.PARMETIS_MINOR_VERSION.PARMETIS_SUBMINOR_VERSION' self.gitcommit = 'v'+self.version+'-p9' self.download = ['git://https://bitbucket.org/petsc/pkg-parmetis.git','https://bitbucket.org/petsc/pkg-parmetis/get/'+self.gitcommit+'.tar.gz']

Hello, 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: 1. PETSc: version 3.14.1 2. VS: version 2022 3. MS MPI: download Microsoft MPI v10.1.2 4. Cygwin

Quick question: Have you considered installing on WSL? I have had much better luck with that on Windows.

This seems to be an incompatibility of ParMetis Windows support and your version:
