parallel install error! #4352
Comments
This error does not make sense to me. Make sure you have not accidentally edited the source file ( Also, you can try building the latest version, mfem v4.7, instead of mfem v4.5. |
@v-dobrev Thank your response. I haven't edited the code, and my machine's default compiler is the GNU C++ compiler, gcc and g++. mpicxx is used for parallel compiling ... |
even if I compile the serial version. the same error took place.! I use the GNU compiler when serial and parallel (v4.5, v4.6 and v4.7)make, How can I solve the compiling error! |
Can you post the exact command(s) you use for building mfem? I can try to reproduce the issue and see if I can find a solution. Also, can you post the output of |
Thank your response, following is the version of GNU complire and the used OS! For serial version, make serial -j 4 For parallel version make parallel -j 4 (preinstalling metis and hyper) |
I think this is an issue with gcc 5. Please use newer gcc version, e.g. I've used v6.3.1 successfully. |
@v-dobrev It's ok for gcc-9. it is indeed the issue of version of compiler. Thank you very much. |
@v-dobrev Hi, when I compiled the parallel example, I came across some errors. install metis-5.1.0 install mfem-4.7 above operation is successfully. However, when I make the parallel example, ~> make ex0p |
One thing is to make sure all packages are built with the same compiler and that Once you make sure the above is true (and it was not true originally) try rebuilding the packages from scratch. If that does not help, you can try rebuilding hypre while adding the following options to the hypre |
I want to run the miniapps --- NS solver, before run the example ,I must install parallel version mfem library. Following the MPI parallel install guiding(hyper and metis are well installed) ,when in mfem4.5, I make parallel j, the following error appeared !
What caused the above error, and how should I recompile?
