Create link in linux (red hat) for abaqus 2018 to run UMAT subroutines

[Murillo__Claudia]

Hi, I am on abaqus 2018 in linux red hat and I am trying to create the link with ifort version 16.0.2. I have run the verification, and shows:

Begin Compiling Abaqus/Standard User Subroutines
Wed 12 Dec 2018 12:04:38 PM EST
End Compiling Abaqus/Standard User Subroutines
Begin Linking Abaqus/Standard User Subroutines
gfortran: unrecognized option '-soname,libstandardU.so'
/usr/bin/ld: : No such file: No such file or directory
collect2: ld returned 1 exit status
Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines
Begin MFS->SFS and SIM cleanup
Wed 12 Dec 2018 12:04:38 PM EST
Run SMASimUtility
Wed 12 Dec 2018 12:04:39 PM EST
End MFS->SFS and SIM cleanup
Abaqus/Analysis exited with errors

 I have to make the changes in the .env file in my home directory since this is a university owned computer. Do you have any recommendation on how to do it? Thanks in advance.

Looks to me as if you're using gfortran, not ifort.

[Murillo__Claudia]

in the lnx86_64.env in my home directory is defined:

import os, re, glob, driverUtils

# fortCmd = "ifort"   # <-- Fortran compiler
fortCmd = "/usr/local/intel/bin/ifort" # Fortran compiler on blackelk
cppCmd  = "g++"     # <-- C++ compiler
abaHomeInc = os.path.abspath(os.path.join(os.environ.get('ABA_HOME', ''), os.pardir)) # <-- Install include dir

# Avoid signal trapping by the Fortran RTE
os.environ["FOR_IGNORE_EXCEPTIONS"] = "1"
# Disable messages from the Fotran RTE
os.environ["FOR_DISABLE_STACK_TRACE"] = "1"

# Do not let QLogic InfiniPath driver set processor affinity.
os.environ["IPATH_NO_CPUAFFINITY"] = "1"

# Add the flag "-free" to the compile_fortran command below to use free-format FORTRAN 90 syntax.

compile_fortran = [fortCmd,
                   '-V',
                   '-c', '-fPIC', '-auto', '-mP2OPT_hpo_vec_divbyzero=F', '-extend_source',
                   '-fpp', '-WB', '-I%I', '-I'+abaHomeInc, '%P']

so I don't know how to fix this...

Claudia, the following part that you posted

End Compiling Abaqus/Standard User Subroutines
Begin Linking Abaqus/Standard User Subroutines
gfortran: unrecognized option '-soname,libstandardU.so'

shows that compilation is donw, and the error message happens for the linking. So I would guess compilation is done with ifort, and then gfortran is invoked for linking.

[Murillo__Claudia]

the linking part of the lnx86_64.env file is defined as:

link_fmu = [cppCmd,
            '-fPIC', '-shared', '-o', '%J', '%M']

link_sl = [fortCmd,
           '-V',           
           '-cxxlib', '-fPIC', '-threads', '-shared','-Wl,--add-needed',
           '%E', '-Wl,-soname,%U', '-o', '%U', '%F', '%A', '%L', '%B', '-parallel',           
           '-Wl,-Bdynamic', '-shared-intel']

link_exe = [cppCmd,
            '-fPIC',
            '-Wl,-Bdynamic', '-Wl,--add-needed', '-o', '%J', '%F', '%M', '%L', '%B', '%O']

is there something to adjust? I appreciate your help.

No way to tell from these excerpts. I don't know this software, I am not even sure what these files are that you posted. Looks like python. There is something screwed up with your environment variables, this

/usr/bin/ld: : No such file: No such file or directory

very fishy. But this all has to do with the setup of your software. Guess you have to ask in their support forum.

[Murillo__Claudia]

It is solved! i followed the step 4 of this page and it worked!

Thank you so much for the help! :)

So what exactly was wrong? What did you change in order to get it run?

[Murillo__Claudia]

I am not sure what was wrong... but I wrote in the terminal: export PATH=/path to ifort.var/:$PATH. Then, I ran the verification again and it worked. I guess that command shows the program the right path. But I am just learning this topic, so I can't tell.
