I think that this needs an Intel library to be linked in, but I'm not sure which one or how to add it.

Comment (by rhaas):
I think when I had this errror before I had to add -openmp to the LDFLAGS (yes linker flags).

Comment (by eschnett):
Cactus does not know how to build executables that have a Fortran main program. (It does not collect this information while configuring.) Riemann1d is the only case where this information is necessary.
F90FLAGS should already contain -openmp, and F90FLAGS should be used for linking in this case.

Comment (by eschnett):
We should rewrite Riemann1d to use a C or C++ main program, and call the Fortran code in a subroutine.

* status: new => closed * resolution: => fixed
Comment:
No rewrite was required. It was sufficient to (programmatically) remove the -openmp flag from the utilities build command.
