Building lapack fails in Windows11

[wknm1997]

Dear all,
Thanks for providing the useful cmake files to help build mumps in Windows. I want to build lapack via cmake according to the description. But I found out, should the cmake --build build -t scalapack here be cmake --build scripts/build -t scalapack ?
After I ran this command, unfortunately, it gave the following error :
`-- Could NOT find MPI_C (missing: MPI_C_LIB_NAMES MPI_C_WORKS)
-- Could NOT find MPI_Fortran (missing: MPI_Fortran_LIB_NAMES MPI_Fortran_WORKS)

I would like to say, I have Intel Parallel Studio2020 MPI and Microsoft MPI. Also, I added their folders to the system environment variables. But still this error has not changed. So I sincerely ask you, is there something wrong with my operation?

thanks

Yesterday, I was using -G "MinGW Makefiles". Today I realized to build Lapack with VS2019+oneAPI instead. But it throws a new error.

Part of the error report is shown here, and I've found that this may have something to do with not specifying "main", but this is a library file. So maybe it has something to do with some bug in the cmake file?

With Intel oneAPI or Parallel Studio, you should not build Lapack and Scalapack. They are included with Intel HPC toolkit. The build of Lapack and Scalapack will not be successful.

Hello, after many days of hard work, I found that although your project can be successfully built for the linux system. But there are still many bugs for Windows system. One of them is that when compiling (cdsz)mumps, the following error will be reported:

dmumps.lib(mumps_c.obj) : error LNK2019: unresolved external symbol DMUMPS_F77, referenced in function dmumps_c
dmumps.lib(mumps_c.obj) : error LNK2019: unresolved external symbol DMUMPS_SET_TMP_PTR, referenced in function DMUMPS_SET_TMP_PTR_C

I found that this is due to the 190 and 245 lines of the mumps_c.c file, and there is an error in the macro definition of the MUMPS_F77 and MUMPS_SET_TMP_PTR functions. Maybe there should be {} instead of ;.
I have to say that after I changed this symbol, the above error did not appear again when compiling. Of course, in this process, there are more than one mistakes in the project. If you are interested, we can communicate.

On Windows, you must use -G Ninja or -G "MinGW Makefiles". The Visual Studio generator is known not to work.

[scivision]

I made a separate Windows readme

[scivision]

MKL supports GCC only on Linux. On Windows to use MKL you need to use the oneAPI compiler too.

[wknm1997]

thank you for your patience. But I still didn't succeed, I used mingw and ninja, but I got .a instead of .lib. During this process, there was still not found lapack, so I manually modified the cache file and let it lock ~/mylibs/libs/lapack.lib.
So I wonder if I should use oneAPI instead of GNU as my compiler. But my cmake defaults to GNU. So I used the following command.
cmake -B build -G "MinGW Makefiles" -DCMAKE_C_COMPILER=D:/Program/Intel/oneAPI/compiler/latest/windows/bin/icx.exe -DCMAKE_CXX_COMPILER=D:/Program/Intel/oneAPI/compiler/latest/windows/bin/icx.exe -DCMAKE_FORTRAN_COMPILER=D:/Program/Intel/oneAPI/compiler/latest/windows/bin/ifx.exe
The obtained cmakeError.log is as follows

To use oneAPI on Windows, it's easiest to use the special command prompt for oneAPI. Under Windows Start, Programs, Intel "oneAPI command prompt for Intel 64 for Visual Studio 2022" or just Windows Search "Intel oneAPI command prompt for Intel 64 for Visual Studio 2022"

If you can't find that special command prompt, you can set the necessary variables to use oneAPI at https://www.intel.com/content/www/us/en/develop/documentation/oneapi-programming-guide/top/oneapi-development-environment-setup/use-the-setvars-script-with-windows.html

This can also be done from PowerShell:

$Env:CC="icx"
$Env:FC="ifx"
$Env:CXX="icx"

cmd.exe /c '"%PROGRAMFILES(X86)%\Intel\oneAPI\setvars.bat" && pwsh'

Whenever compiling programs on Windows, the proper environment variables and/or command prompt must be used. This is for any code project on Windows, not just MUMPS.

Use a fresh build directory so that the Intel compilers are properly recognized and not mixed up with the failed GCC build.

[scivision]

Then the command line from oneAPI command prompt would be like:

cmake -G Ninja -B build -DCMAKE_C_COMPILER=icx -DCMAKE_Fortran_COMPILER=ifx -DBUILD_SINGLE=yes -DBUILD_DOUBLE=yes -DBUILD_COMPLEX=yes -DBUILD_COMPLEX16=yes

[wknm1997]

Then the command line from oneAPI command prompt would be like:

cmake -G Ninja -B build -DCMAKE_C_COMPILER=icx -DCMAKE_Fortran_COMPILER=ifx -DBUILD_SINGLE=yes -DBUILD_DOUBLE=yes -DBUILD_COMPLEX=yes -DBUILD_COMPLEX16=yes

Thank you, with your patient help for so many days, I finally successfully compiled mumps with windows. Thanks for your contribution to the project.I will share my joy with you as soon as possible when my paper is published!

[wknm1997]

[scivision]

You need to have the correct command prompt and environment variables as above, or even if someone emailed you the binary libraries, the build would still fail. The correct programming environment is essential for building any Windows program.

[scivision]

The default build type for MUMPS is Release (optimized)

[scivision]

The Matlab interface is from 2006; I'm not sure if it is maintained. The Matlab interface didn't seem to totally work for me. I would work with plain MUMPS.
