[Nek5000-users] Compilation of nek5000 in ubuntu

Wed Jan 14 05:31:37 CST 2015

Hi Kamal,

I am really thankful that you give so detailed information on compilation of Open-mpi. Everything went well when following your first 4 steps except for Step 5 in which creation of dir /sur/local/openmpi/share was denied. So I re-do Step 5 with command "sudo make check install", and then it compiled well without errors.

Then I followed Step 6 but it was found that no mpif77 nor mpicc files were under dir /use/local/openmpi/. After checking files under dir /use/local/openmpi/bin, there exist mpiff77 and mpicc files. So finally I changed makenek to "F77 = /usr/local/openmpi/bin/mpif77" and " CC = /usr/local/openmpi/bin/mpicc" and then type "./makenek eddy_uv".

Unluckily, the error came again as following:

--------------------------------------------------------------------------
Unfortunately, this installation of Open MPI was not compiled with
Fortran 77 support.  As such, the mpif77 compiler is non-functional.
--------------------------------------------------------------------------
FATAL ERROR: Basic compiler test for /usr/local/openmpi/bin/mpif77 failed!

It seems fortran 77 not ready yet. Do you have any comments about it?

Thanks,

Simon

  Hi Simon,

   1) Download the Open-Mpi file from here : www.open-mpi.org/software/ompi/v1.8/downloads/openmpi-1.8.4.tar.gz<http://www.open-mpi.org/software/ompi/v1.8/downloads/openmpi-1.8.4.tar.gz>, unpack it
   2) Create a folder ' sudo mkdir  /usr/local/openmpi '
   3) Go to the unpacked openmpi-1.8.4 folder and do ./configure --prefix = /usr/local/openmpi
   4) Then just type ' make '
   5) Then ' make check install '

   This will install open-mpi in the folder /usr/local/openmpi, now your mpi files will be in this folder.

   6) Open makenek and change ' F77 = /use/local/openmpi/mpif77 ' and ' CC = /usr/local/openmpi/mpicc '  or you can the path to ./bashrc file if you don't want to do this step.

   I hope this should work for you.

 Best Regards,
  Kamal

Hi Kamal,

Thank you very much for the suggestion. As I am a Linux user at very basic level, could you please tell a little bit more details on reinstalling open-mpi? Are u suggesting me reinstall the same version as installed in ubundu, or any other version? If it should be a certain version, I will download and install in.

To tell the truth, I installed a package f2c that can translate fortran77 to c language, but it does not help here. Do you think do u have to install fortran77 in Ubuntu? It is said installing f77 will cause more errors in the latest version of Ubuntu.

Thanks for your reply again.

Sincerely,
Simon

  Hi Simon,

  I would suggest you to reinstall OPEN-MPI in ubuntu and use mpif77 compiler.

  Best,
  Kamal

 PS: Install Open Mpi in a separate folder and the add the path in ./bashsrc or to the makenek directly

Hi there,

I am compiling the eddy example in my ubuntu OS, but the system returns error with "Error: Can't open included file 'mpif.h'". The fortran compiler in makenek file was changed to gfortran since mpif77 gives error:

Unfortunately, this installation of Open MPI was not compiled with

Is there anyone experience the same problem when compiling in ubuntu? You assistance will be greatly appreciated.

Sincerely,
Simon
