If you use PAPI_DIR=BUILD to make Cactus build PAPI itself (which you<br>
seem to do) then it will install the created PAPI library to<br>
<br>
<br>
Cactus/configs/ET_dirac/scratch/external/PAPI<br>
<br>
and the include file would be there.<br>
<br>
Cactus at that point should set up a include search path to find files<br>
there, which you can check in:<br>
<br>
Cactus/configs/ET_dirac/bindings/Configuration/Capabilities/make.PAPI.defn<br>

That one I suspect is actually being pulled in by HDF5 which can use<br>
the sz library but I have seen systems (Windows using MSYS admittedly)<br>
where the sz library was called szip. <br>
<br>
The actual line that cases the failure is probably this one:<br>
<br>
<a href="https://github.com/EinsteinToolkit/ExternalLibraries-HDF5/blob/abf8dbf78e767b7e2ae3e96b098af3dceb5dede0/src/detect.sh#L188" target="_blank" rel="noopener noreferrer" data-auth="NotApplicable">https://github.com/EinsteinToolkit/ExternalLibraries-HDF5/blob/abf8dbf78e767b7e2ae3e96b098af3dceb5dede0/src/detect.sh#L188</a><br>
<br>
You could try two things to avoid this:<br>
<br>
1. build your own HDF5 by setting HDF5_DIR=BUILD<br>
2. find out where libsz.so or libsz.a are located (by using he "module<br>
show" command on the HDF5 module or asking the admins) and adding that<br>
directory to HDF5_LIB_DIRS<br>
<br>
