Problem building CosmoMC

Post by chien lin » July 02 2019

Hello,

I am trying to compile CosmoMC (nov2016) on my laptop running Ubuntu 18.04, and these errors repeatedly show up.

Code: Select all

mpif90 -cpp -O3 -ffast-math -ffree-line-length-none -fopenmp -fmax-errors=4 -march=native -DMPI -I../camb/ReleaseMPI  -JReleaseMPI -IReleaseMPI/ -c szcounts.f90 -o ReleaseMPI/szcounts.o
ifort: command line warning #10006: ignoring unknown option '-ffast-math'
ifort: command line warning #10006: ignoring unknown option '-ffree-line-length-none'
ifort: command line warning #10006: ignoring unknown option '-JReleaseMPI'
And eventually it cannot continue compiling.

Code: Select all

szcounts.f90(41): error #7002: Error in opening the compiled module file.  Check INCLUDE paths.   [PRECISION]
    use PRECISION
--------^
szcounts.f90(43): error #6683: A kind type parameter must be a compile-time constant.   [DL]

/tmp/ifortE4Ye0O.i90(59): catastrophic error: Too many errors, exiting
compilation aborted for szcounts.f90 (code 1)
Makefile:286: recipe for target 'ReleaseMPI/szcounts.o' failed
make: *** [ReleaseMPI/szcounts.o] Error 1

I use 'Make' command with ifort version 19, and the instruction I am following is from this paper : https://arxiv.org/pdf/1808.05080.pdf .

I am completely new to configuring source code. Please could anyone help me? Thank you in advance!

Regards,
Chien Lin

Check if "mpif90" is actually using ifort and not gfortran.

Hi,

Thank you for your reply. I've tried the command

Code: Select all

mpif90 --version
, and it returns

Code: Select all

ifort (IFORT) 17.0.8 20180907
Copyright (C) 1985-2018 Intel Corporation.  All rights reserved.
, so I believe the mpif90 is indeed using ifort.

Try the latest master from github rather than the old 2016 version.
