Dear NEK users, I am trying to compile nek model on NERSC machines edison/hopper, encountering an error. Tail of the compilation message is as below: _____________________________________________________________________ /global/homes/r/rtumkur/nek5_svn/trunk/nek/prepost.f(2482): warning #5117: Bad # preprocessor line #ifdef MPIIO -^ /global/homes/r/rtumkur/nek5_svn/trunk/nek/prepost.f(2484): warning #5117: Bad # preprocessor line #else -^ /global/homes/r/rtumkur/nek5_svn/trunk/nek/prepost.f(2486): warning #5117: Bad # preprocessor line #endif -^ compilation aborted for /global/homes/r/rtumkur/nek5_svn/trunk/nek/prepost.f (code 1) make: *** [obj/prepost.o] Error 1 make: *** Waiting for unfinished jobs.... ifort: command line warning #10006: ignoring unknown option '-Mpreprocess' ____________________________________________________________________ Here are the steps I have taken leading up the error. I downloaded the 1. Downloaded and build the nek svn co https://svn.mcs.anl.gov/repos/nek5/ nek5_svn cd nek5_svn/trunk/tools/ ./maketools all 2. Updated the makenek file as per the instructions provide at the link https://www.nersc.gov/users/computational-systems/hopper/programming/compili... Accordingly, I have loaded Intel compiler module and specified the wrapper in makenek: # Fortran compiler F77="ftn" # C compiler CC="cc" Also included OpenMP Compilation in the general compiler flag: # generic compiler flags G="-g -openmp" 3. Compiled the code makenek sprcyl Any help in resolving this error is much appreciated. I have inserted the SIZE file and makenek file for your reference. ____________________SIZE___________________________ C Dimension file to be included C C HCUBE array dimensions C parameter (ldim=2) parameter (lx1=6,ly1=lx1,lz1=1,lelt=1500,lelv=lelt) parameter (lxd=9,lyd=lxd,lzd=1) parameter (lelx=1,lely=1,lelz=1) parameter (lp = 32768) parameter (lelg = 50000) parameter (lzl=3 + 2*(ldim-3)) c parameter (lx2=lx1-2) parameter (ly2=ly1-2) parameter (lz2=lz1 ) parameter (lx3=lx1) parameter (ly3=ly1) parameter (lz3=lz1) c c parameter (lpelv=lelv,lpelt=lelt,lpert=3) ! perturbation c parameter (lpx1=lx1,lpy1=ly1,lpz1=lz1) ! array sizes c parameter (lpx2=lx2,lpy2=ly2,lpz2=lz2) c parameter (lpelv=1,lpelt=1,lpert=1) ! perturbation parameter (lpx1=1,lpy1=1,lpz1=1) ! array sizes parameter (lpx2=1,lpy2=1,lpz2=1) c c c parameter (lbelv=lelv,lbelt=lelt) !
