MUMPS is not available as an official port in vcpkg. I assume you used the fortran-ports branch of my fork with the Fortran compiler set to GNU. GNU/gfortran support is experimental only at the moment since MinGW does not support linking to the new UCRT yet (hence you are seeing the errors). Please take a look at #1098 and #485 for more information.

You may want to switch the compilers. Intel should work but is not free. PGI is free and should work as well, but you need to install Visual Studio 2015 (although after that you can use the Visual Studio 2017 toolset). GNU has the problems mentioned above. Flang is the new hope because it is free but it is still in kind of early develepment states. Maybe @isuruf or @xoviat can comment on what the current status of Flang is.

Are there any problems with flang? The main issue is that we haven't had enough battle testing but that requires people to use it.

[albertziegenhagel]

I did not do a lot of testing as well. The last time when I tried to build MUMPS there was an error about a missing include file although my first impression was that all -I<path> arguments where correct.

@xoviat Is flang-5.0.0-vc14_1 still the most up-to-date build of flang in the conda packages? If not, just let me know which packages is up to date and I will update the flang version that is downloaded in my fortran branch.

[isuruf]

Latest packages

clangdev:       5.0.0-flang_3       conda-forge [flang vc14]
flang:          5.0.0-vc14_20180101 conda-forge [vc14      ]
libflang:       5.0.0-vc14_20180101 conda-forge [vc14      ]
openmp:         5.0.0-vc14_0        conda-forge [vc14      ]

[albertziegenhagel]

Thanks! Are those stable links or will they be removed as soon as you upload an updated package?

[isuruf]

If you want, I can set a label conda-forge/label/archive so that even if these packages were removed from conda-forge main channel, it will be available in the conda-forge/label/archive channel

[albertziegenhagel]

I think that would be great!

[isuruf]

Done. Now, even if they are removed from the main codna-forge channel, the links will be stable.

flang should have been able to build MUMPS without any issues. Let me attempt to reproduce this...

FYI Perhaps you should add triplets to your branch.

So the first problem that I encountered is that the reference LAPACK failed to build. However, I was able to build the reference lapack without any problems here.

[albertziegenhagel]

FYI Perhaps you should add triplets to your branch.

I think the policy of vcpkg is not to have to many default triplets provided. Instead the user should adjust the triplets himself if he needs to.

So the first problem that I encountered is that the reference LAPACK failed to build.

The last time I checked it was working correctly. I will try to update Flang and check again. Thanks for the hint.

[sweety2142]

Thanks guys~ I solved problem with option adding

[ghost]

Sorry, I forgot to mention this: flang currently requires the CMake development branch; the version available on conda is patched until the next release comes out. That might be why the build is currently failing.

[ghost]

Currently the best build performance is available using the CMake development branch and kitware ninja. Eventually patches will be merged into mainline, but ninja is moving very slowly.
