#699: FFTW option ----------------------------+----------------------------------------------- Reporter: barry.wardell | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Resolution: | Keywords: ----------------------------+-----------------------------------------------
Comment (by eschnett):
We should not make boilerplate changes to option lists. This is likely to break things. Either an option list is unused, and in this case, leaving it at its old state makes it easiest to update it, because then one doesn't have to find out which untested changes were applied. Or the option list is used, in which case it is working, and making changes is not necessary.
In this case, FFTW_DIR is for version 2 of the FFTW library, whereas FFTW3_DIR is for version three. These two libraries are not compatible. FFTW is supported by Cactus using the old configuration mechanism (i.e. without using a thorn to configure it). I would either leave this in (if it works), or remove these definitions (under the assumption that FFTW version 2 is not installed on these systems any more). However, the latter assumption is dangerous.
I would rather go through this machine by machine, updating those option lists that are used (and where people care), and moving the other option lists to a "retired" or "nobody looked at this in the past year" directory.
