I would like to compile PETSc under Windows with Intel MKL and Pardiso. I tried to run ./configure with --with-blaslapack-dir=’/c/PROGRA~2/Intel/oneAPI/mkl/latest’ --with-mkl\_pardiso-dir=’/c/PROGRA~2/Intel/oneAPI/mkl/latest’ Unfortunately, this gave an error: “Could not find a functional BLAS. Run with --with-blas-lib= to indicate the library containing BLAS.” Then, I tried --with-blaslapack-include=’’ --with-blaslapack-lib=’/c/PROGRA~2/Intel/oneAPI/mkl/latest/lib/intel64/mkl\_blas95\_lp64.lib’ (similar to --with-blaslapack-include=’’ --with-blaslapack-lib=’/mingw64/bin/libopenblas.dll’ which worked) This gave the following error: “You set a value for --with-blaslapack-lib=, but [’/c/PROGRA~2/Intel/oneAPI/mkl/latest/lib/intel64/mkl\_blas95\_lp64.lib’] cannot be used” Any idea what I could do to use Intel MKL and Pardiso? Thank you! ---

I think the easiest would be to compile PETSc with PARDISO, and then let FreeFEM pickup PETSc variables. I cannot test this because I don’t have oneAPI on Windows, but there are PETSc configure scripts available with this. Would that suit your needs? ---

Sure! Where would I find those configure scripts? And will I have a working configure line for PETSc with MKL Pardiso on Windows in the end? Should I follow the windows install instructions to achieve this? Thank you! ---

There is on here that you should be able to adapt I think: [config/examples/arch-ci-mswin-opt-impi.py · main · PETSc / petsc · GitLab](https://gitlab.com/petsc/petsc/-/blob/main/config/examples/arch-ci-mswin-opt-impi.py#L14). You’ll need to follow the installation prerequisites, with respect to the packages that you need to install on MinGW. Then, do `make petsc-slepc` in `3rdparty/ff-petsc`, but change in the configure line the `--with-blaslapack-lib` with the one you are seeing in PETSc repo. ---

I am getting “You set a value for --with-blaslapack-lib=, but [’-L/c/PROGRA~2/INTEL/oneAPI/mkl/latest/lib/intel64/’, ‘mkl\_intel\_lp64\_dll.lib’, ‘mkl\_sequential\_dll.lib’, ‘mkl\_core\_dll.lib’] cannot be used” or You set a value for --with-blaslapack-lib=, but [’-L/e/Programme/ComposerXE2013SP1/mkl/lib/intel64’, ‘mkl\_intel\_lp64\_dll.lib’, ‘mkl\_sequential\_dll.lib’, ‘mkl\_core\_dll.lib’] cannot be used The configure line you sent is for cygwin, right? Is it expected also to work under mingw64? Where would I enter the modified configure line in 3rdparty/ff-petsc? ---

Could you please share your `configure.log`? Also, I’m seeing you posted a different issue on the `petsc-maint` mailing list. Do you need to use Visual Studio with FreeFEM, or would you be content sticking to MinGW? ---

Dear prj, I would like to use PETSc + Intel MKL Pardiso. I am not attached to either cygwin or MinGW. I contacted petsc-maint with the cygwin question, because that’s what they propose on their website. Just trying out different routes here. At least I got PETsc to work with MinGW using GNU compilers following the instructions on your website. However, only with OpenBlas and without PARDISO. I cannot attach any documents (new user). Any other way to send you configure.log? Should I just post the full log? Thank you! ---

OK, if you don’t care about Visual Studio, it will be easier to stick to MinGW, I think. Can’t you upload the log somewhere and send me the link? ---

Sure (see [GigaMove 2.0](https://gigamove.rwth-aachen.de/de/download/85e112dbca1a072ddaf4704f0c7814e7)). I am a little confused here. Will I be able to link to an existing Visual Studio 2019 project in the end with MinGW or not? ---

What do you mean by “link”? FreeFEM can’t be “linked” (e.g., with a compile line) with other software. ---

Ok, I see. I thought there would be an easy way to use PETSc on Windows via FreeFEM from an existing project. And since you have a lot of experience with building PETSc on Windows, I thought this might be the place to ask. Thank you! ---

OK, if you are mostly interested about PETSc + Visual Studio, best to stick to the PETSc mailing list. I’m a developer there as well so I’ll help you if I can, though other developers are more used to Cygwin, so they’ll most likely do a better job than me. ---

Ok. I will stick to petsc-maint then, but will try both routes via cygwin and mingw. Thank you for your help! ---

In MinGW, there is an issue with your option `--with-blaslapack-lib`. Maybe you could try: `--with-blaslapack-lib=[/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_intel_lp64_dll.lib,/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_sequential_dll.lib,/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_core_dll.lib]` You’ll have to double check that these `.lib` exist (maybe it’s `libmkl_intel_lp64_dll.lib` & co. instead of simply `mkl_intel_lp64_dll.lib`?). ---

I double checked that these libraries exist. Unfortunately, I still get ``` UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): ``` * * * You set a value for --with-blaslapack-lib=, but [’/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl\_intel\_lp64\_dll.lib’, ‘/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl\_sequential\_dll.lib’, ‘/e/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl\_core\_dll.lib’] cannot be used (see [GigaMove 2.0](https://gigamove.rwth-aachen.de/de/download/2300ab3028c40d819706cf6245b54c42)) Thank you! ---

I see ```auto C:/Ruby30-x64/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: E:/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_intel_lp64_dll.lib(_dgetrs_lp64.obj):(.text[dgetrs]+0x1d): undefined reference to `__security_cookie' C:/Ruby30-x64/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: E:/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_intel_lp64_dll.lib(_dgetrs_lp64.obj):(.text[dgetrs]+0xd4): undefined reference to `__security_check_cookie' C:/Ruby30-x64/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: E:/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_intel_lp64_dll.lib(_dgetrs_lp64.obj):(.text[dgetrs]+0x187): undefined reference to `__security_check_cookie' C:/Ruby30-x64/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: E:/FGH/Programme/ComposerXE2013SP1/mkl/lib/intel64/mkl_intel_lp64_dll.lib(_dgetrs_lp64.obj):(.xdata+0x10): undefined reference to `__GSHandlerCheck' ``` So it looks like it’s not possible to link a code compiled with Intel toolchain and one compiled with MinGW toolchain… ---

I see you are using the same compilers then, so it’s expected to work indeed. Glad you got that straightened out.
