Hello Federico,
Can anyone give me some hint?
I can compile the ET_Proca release of the ET one BW using the release option list.
this change is likely due to a change in the BW programming environment (which may have slipped proper announcement channels).
The error you describe (incorrect number of arguments to CCTK_LOOP3STROFF_NORMAL) is most likely due to mixing differing versions of the codes.
Eg the argument list of CCTK_LOOP3STROFF_NORMAL increased from 23 to 24 in e896df97

I cannot give a definitive answer as to why different different versions may be used. One guess would be that something confused make. This can happen if you mix using simfactory's "sync" command to copy source code to a cluster with editing / updating / downloading code directly on the cluster.
In that case you can try and see if a full fresh recompile using, in order of severity of wiping the configuration
make sim-clean make sim-realclean rm -rf configs/sim
before a fresh
simfactory/bin/sim build --thornlist thornlists/einsteintoolkit.th
is used.
Note that currently "master" does not build on BW due to a failure to properly detect the F90 compiler though that failure happens during the CST phase.
Yours, Roland
