Change __attribute__((packed)) to /* __attribute__((packed)) */ in include/petscmath.h and run make again. I think you should install a new version of Microsoft's compilers etc. Barry

Hi Barry

Thanks for your advice. I use AI help me that change the file on the petsc-3.24.1/arch-mswin-c-opt/externalpackages/petsc-pkg-parmetis-f5e3aab04fd5/headers/gk_arch.

The change is from:

#ifdef __MSC__ #include "ms_stdint.h" #include "ms_inttypes.h" #include "ms_stat.h" #else #ifndef SUNOS #include <stdint.h> #endif #if !defined(WIN32) && !defined(__MINGW32__) #include <sys/resource.h> #endif #include <inttypes.h> #include <sys/types.h> #include <sys/time.h> #endif

To:

#if (defined(__MSC__) || defined(_MSC_VER)) && defined(_MSC_VER) && _MSC_VER < 1900 #include "ms_stdint.h" #include "ms_inttypes.h" #include "ms_stat.h" #else #ifndef SUNOS #include <stdint.h> #endif #if !defined(WIN32) && !defined(__MINGW32__) && !defined(_MSC_VER) #include <sys/resource.h> #endif #include <inttypes.h> #include <sys/types.h> #if !defined(_MSC_VER) #include <sys/time.h> #endif #endif

Then I configure the PETSc:

./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

It seems good, but then I make it

it have the error:

make[3]: *** [gmakefile:211: arch-mswin-c-opt/obj/src/sys/objects/device/interface/mark_dcontext.o] Error 2 make[3]: Leaving directory '/cygdrive/g/mypetsc/petsc-3.24.1' make[2]: *** [/cygdrive/g/mypetsc/petsc-3.24.1/lib/petsc/conf/rules_doc.mk:5: libs] Error 2 make[2]: Leaving directory '/cygdrive/g/mypetsc/petsc-3.24.1' **************************ERROR************************************* Error during compile, check arch-mswin-c-opt/lib/petsc/conf/make.log Send it and arch-mswin-c-opt/lib/petsc/conf/configure.log to [email protected] <mailto:[email protected]> ******************************************************************** make[1]: *** [makefile:44: all] Error 1 make: *** [GNUmakefile:9: all] Error 2

The new configure.log and make.log is attached below.

I don't know if it is caused by the change I made or the other problems.

So I ask for your help again. Looking forward your reply!

sinserely, Cheng.

Parmetis has its own definitions for many C standard types, etc in headers\ms_stdint.h that duplicate what is available in stdint.h on Unix systems. Normally, this gets included when __MSC_ is defined instead of stdint.h (in gk_arch.h).

But for some reason, with your system it appears that Microsoft's stdint.h is also getting included; presumably brought in through some other system include file since it is only included in one place.

$ git grep stdint.h headers/gk_arch.h: #include "ms_stdint.h" headers/gk_arch.h: #include <stdint.h> headers/ms_inttypes.h:#include "ms_stdint.h" headers/ms_stdint.h:// ISO C9x compliant stdint.h for Microsoft Visual Studio

You have a fairly old VisualStudio, 2022. Can you upgrade to the latest? Let us know if this resolves the problem.

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... and it is "petsc-pkg-parmetis-f5e3aab04fd5.tar.gz"

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 <git://https//bitbucket.org/petsc/pkg-parmetis.git','https://bitbucket.org/petsc/pkg-parmetis/get/'+self.gitcommit+'.tar.gz>']

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:
