After reading through the Carpet documentation and then digging deep into the source code for CarpetLib, I discovered that there seem to be flags to compile Carpet with support for different types. I passed -DCARPET_ALL_REAL in as part of CPPFLAGS in my optionlist, but attempting to compile with other real types leads to compile-time errors about undefined functions: apparently headers for prolongation functions for all the types are generated, but somehow the corresponding definitions aren't being be linked correctly.</div><div style="font-family:Helvetica,Arial;font-size:13px"><br></div><div style="font-family:Helvetica,Arial;font-size:13px">I'm not sure what is going wrong, but I am also unable to find any examples of how support for other types is supposed to be enabled, so I am unsure if I am doing this right.</div><div style="font-family:Helvetica,Arial;font-size:13px"><br></div><div style="font-family:Helvetica,Arial;font-size:13px">So my question is: what is the status of support for grid functions of types besides CCTK_REAL8 in Carpet? Does this feature work, and if so, how can I enable support for all Cactus-supported real types in Carpet?</div><div style="font-family:Helvetica,Arial;font-size:13px"><br></div><div style="font-family:Helvetica,Arial;font-size:13px">Cheers,</div><br><div class="gmail_signature"><span style="font-family:-apple-system;font-size:14px">— Erik Wessel</span><br style="font-family:-apple-system;font-size:14px"><span style="font-family:-apple-system;font-size:14px">Department of Physics</span><br style="font-family:-apple-system;font-size:14px"><span style="font-family:-apple-system;font-size:14px">University of Arizona</span></div></body></html>
