I'm trying to use gfortran with Abaqus 2016 on Ubuntu 16.04. I've already modified the .env file accoring to that : http://home.iitk.ac.in/~saiwal/computing/abaqus2016-2017-gfortran-compiler/

So the gfortran itself does not throw any errors at me anymore. But after using abaqus -verify -user_std -verbose

I get :

  • Abaqus instructions for your version would specify which compilers are compatible and where to get the corresponding abaqus build. Widely used fortrans i.e. Intel, pgi, gfortran have zero runtime library compatibility. – tim18 Dec 17 '17 at 20:54
  • Also, certain versions of gfortran are not compatible with other versions (there are changes in the ABI). – Vladimir F Героям слава Dec 18 '17 at 09:48
  • It would be useful to try the command `gfortran -c -fPIC -I/home/konrad/verify -I. -I/home/konrad/Simulia/solver/linux_a64/code/bin/SMAExternal/pmpi-9.1.2/include std_user.f` yourself and tell us what happens when you execute it. – Vladimir F Героям слава Dec 18 '17 at 09:49
  • I'm sure the OP knows abaqus officially only supports intel/ifort, so you wont get anywhere looking at the abaqus docs or calling support. If this is going to work you might need to uninstall/reinstall abaqus, checking the boxes to install and verify user sub support. – agentp Dec 18 '17 at 13:28

There were two things missing:

-The CAA package (since 2016 version the installer is separated to several files)

CAA developer software for Abaqus APIs: output database (ODB) C++ API,
user subroutines API,Abaqus Scripting Interface API, and SIMULIA Co-Simulation 
Engine C++ API. This software includes libraries and .h header files. 
The CAA (Component Application Architecture) API software is needed for
using user subroutines and compiling and building ODB, SIM, or results file 
postprocessing applications.

It is recommended that you always install the CAA (API) software, even if
you are not sure that you will need it; otherwise, you may find that some
components need to be installed later before you can upgrade to a fix 
pack (hot fix).

-in the lnx86_64.env file I've change the lines :

fortCmd = "gfortran"   # <-- Fortran compiler
cppCmd  = "gcc"     # <-- C++ compiler

to

fortCmd = "gfortran"   # <-- Fortran compiler
cppCmd  = "gfortran"     # <-- C++ compiler

So for any future references to have it running change link_sl and compile_fortran to :

compile_fortran = (fortCmd + " -c -fPIC -I%I")

link_sl = (fortCmd + 
   " -gcc-version=%i -fPIC -shared " + 
   "%E -Wl,-soname,%U -o %U %F %A %L %B -Wl,-Bdynamic " +
`   " -lifport -lifcoremt")

fortCmd = "gfortran"   # <-- Fortran compiler
cppCmd  = "gfortran"     # <-- C++ compiler
