Hello Matt,

Cactus/arrangements/ExternalLibraries/PAPI/src/stats.c(20): catastrophic error: cannot open source file "papi.h" #include <papi.h>

I cannot find the header file anywhere (i.e. in ET or /usr/include) so I am not sure how to proceed. Is PAPI a necessary library for ET function?

If you use PAPI_DIR=BUILD to make Cactus build PAPI itself (which you seem to do) then it will install the created PAPI library to

Cactus/configs/ET_dirac/scratch/external/PAPI

and the include file would be there.

Cactus at that point should set up a include search path to find files there, which you can check in:

Cactus/configs/ET_dirac/bindings/Configuration/Capabilities/make.PAPI.defn

Compiling with it excluded from the thornlist gives me

/usr/bin/ld: cannot find -lsz make[1]: *** [/lustre/dirac/home/dc-elle1/ET/Cactus/exe/cactus_ET_dirac] Error 1

which I am not sure is connected as I am compiling from scratch.

That one I suspect is actually being pulled in by HDF5 which can use the sz library but I have seen systems (Windows using MSYS admittedly) where the sz library was called szip.

The actual line that cases the failure is probably this one:

You could try two things to avoid this:

1. build your own HDF5 by setting HDF5_DIR=BUILD 2. find out where libsz.so or libsz.a are located (by using he "module show" command on the HDF5 module or asking the admins) and adding that directory to HDF5_LIB_DIRS

and

for details on these option list variables.

Thanks,
