Hi Simon, it seems like you do not have gfortran installed correctly, or a bugged one install, and some how, gcc or g++ (which are default in linux systems) is trying to link up your fortran codes in genbox.f generating those errors. In order to upgrade all the utilities and compilers, link files, make sure you install all this utility files and compilers before you install nek5000. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- mesa-utils, tcsh, subversion, libx11-*, libxt-dev , xfonts-100dpi, xfonts-100dpi-transcoded xfonts-75dpi, xfonts-75dpi-transcoded, gfortran, gcc, g++, mpich2, vim ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Hope this would work for you Sincerely, Tanmoy Best Regards, Tanmoy On Sun, Feb 22, 2015 at 3:21 AM, <[email protected]> wrote:

Dear nek5000 users,

Hello everyone, I am a new user. I got stuck when I follow the Quick Start page <https://nek5000.mcs.anl.gov/index.php/Quick_Start>. I follow up till the command - "maketools all" Trouble happens.

The error occurs : genbox.f:(.text+0x174cc): undefined reference to `_gfortran_transfer_real_write'

And a number of similar errors. Does anyone know how to correct that? Thank you.

Regards, Simon
