Hello Federico,

this is just a guess: issues with Fortran modules, can be caused by updates of the Fortran compiler (since they are specific to the exact compiler version).

The compiled Fortran modules are stored in the "configs/sim/scratch" directory and are removed (and then recompiled) by both the "clean" and the "realclean" targets.

Can you try if you can compile after running:

make sim-clean

please (and then check before compiling that configs/ET/scratch/cctk.mod is not present)? Looking at your log file, this does not seem very likely to help (since you have "COMPILING CactusBase/Fortran/src/cctk.F90") but it may be worth a try at least.

You may also want to check that there is no file named "cctk.mod" anywhere else (eg by running "find /home/federico/Documents/EinsteinToolkit/Cactus/ -name cctk.mod").

The toolkit compiles on a freshly installed Ubuntu 18.04 VM for me (and with gcc 6, gcc 7, gcc 8, gcc 9 on my Debian Bullseye workstation), so there may be something odd going on.

Would you mind attaching the file cctk.mod produced on your system as well as the machine ini file for WS03 (WS03.ini in simfactory/mdb/machines), please?

Yours, Roland

Dear EinsteiToolkit user support,

I am recently experiencing some issues compiling the ETK standard thornlist (version "Mayer") on my Workstation with Ubuntu 18.04 as OS.

Once I could compile the ETK (version "Tesla") correctly but after some recent upgrades, I cannot compile any thornlist within my machine. So I tried downloading the ETK most recent version (namely "Mayer) and build the standar thornlist from scratch, but I am always getting the same error.

I attach the compilation output of my last trial (namely the "ET" configuration). In order to build the ET configuration, I used the following command:

./simfactory/bin/sim build ET --machine=WS03 --thornlist=./thornlists/ einsteintoolkit.th >& compilation.out

The WS03 machine was defined by me in a "standard" way, and the WS03.ini file is calling the generic.cfg, generic.run and generic.sub files.

The current version of gcc, g++, gfortran and cpp compilers that I am using are the 7.4.0 GNU ones, although I tried also the 5.5 and 8.3 ones (always getting the same error). In order to set the version of the compiler, I am currently using the following command (for gcc - for the other compiler it is equivalent):

sudo update-alternatives --config gcc

As you can see, the last lines in the compilation.out files are the following:

Checking status of thorn CalcK COMPILING EinsteinAnalysis/CalcK/src/CalcK.F90 f951: Fatal Error: Reading module ‘cctk’ at line 1310 column 20: Unexpected EOF compilation terminated. /home/federico/Documents/EinsteinToolkit/Cactus/configs/ET/config-data/make.config.rules:409: recipe for target 'CalcK.F90.o' failed make[3]: *** [CalcK.F90.o] Error 1 /home/federico/Documents/EinsteinToolkit/Cactus/lib/make/make.thornlib:112: recipe for target 'make.checked' failed make[2]: *** [make.checked] Error 2 /home/federico/Documents/EinsteinToolkit/Cactus/lib/make/make.configuration:181: recipe for target '/home/federico/Documents/EinsteinToolkit/Cactus/configs/ET/lib/libthorn_CalcK.a' failed make[1]: *** [/home/federico/Documents/EinsteinToolkit/Cactus/configs/ET/lib/libthorn_CalcK.a] Error 2 Makefile:256: recipe for target 'ET' failed make: *** [ET] Error 2

Do you have any suggestions for me?

Best regards, Federico Cipolletta.

Hello all,

closing off this thread. Federico responded to me in private email stating that after installing Ubuntu 18.04 from scratch the error went away.

Yours, Roland
