[petsc-users] Problem in some macro when using VS+intel cl

[冯上玮]

I've followed your advice and include the header's file and libraries in Visual Studio. Such "error" still shows but I can build the project! It's strange!
I expand the CHKERRQ macro and find the error actually locates at



 
What I know from google is that the "__builtin_expect__" is defined in GCC, so is it unsolvable in Windows with visual studio C compiler or Inter C compiler?

Hi, 


After failure with MS-MPI once and once again, I tried icl+oneAPI and succeeded in installing and testing PESTc in Cygwin!


However, (always however) when I copied the example code on Getting Started page on visual studio, there are tons of error like:

I just wonder where the problem locates, I've googled this error message and it seems that it's induced by the difference of compilers, c.f. https://stackoverflow.com/questions/42136395/identifier-builtin-expect-is-undefined-during-ros-on-win-tutorial-talker-ex. But Intel says that they also provide such thing on icl, and I actually use this compiler instead of visual studio cl... 




The IDE is not showing the actual error message. Are you sure that your IDE build has the right includes and libraries? You can
get these using


  cd $PETSC_DIR
  make getincludedirs
  make getlinklibs


  Thanks,

Anyway, the project could be built if I delete these error-checking macro.


Installing feedback (or as a test result):
When configure on windows, only icl + impi works, and in this case, both --with-cc and --with-cxx options need to point out the version like: --with-cc-std-c99 and --with-cxx-std-c++'ver'. Other combinations such as cl + impi, icl + msmpi, cl + msmpi never work. My tutor told me that older version of msmpi may work but I never try this.
