Hello Elena, > Thank you for answering. I still have problems. This is the output of > the compilation before the error:
Thanks for including the log file. The error show there is --8<-- ld: library not found for -lsz collect2: error: ld returned 1 exit status --8<-- indicating that the linker did not find the libsz library file. This library is used by HDF5. The log file does not quite contain enough information to let me know which HDF5 was used. For that it would have to be a log file form a fresh compilation, eg after removing the `configs` directory using rm -rf configs Looking at the Option list (and the paths in the error messages) this seems to be a macOS laptop using macports, yes? In that case the first thing to check would be that you have installed the packages listed under the "Prerequisites" section in https://github.com/einsteintoolkit/jupyter-et/blob/master/tutorial-server/notebooks/CactusTutorial.ipynb Which will install a copy of hdf5 from macports. Though, having just tested this on my own macbook (Sonoma 14.6.1, newest XCode and macports) I get the same error. So let's see... Ok, there's a libsz in /opt/local/lib/libaec/lib/ which (one way, not the best but should do for now until I can update the instructions more properly) can be made available by doing ``` export LIBRARY_PATH=/opt/local/lib/libaec/lib ``` before running `sim build`. With this I still get some warnings that are however harmless and I can run the resulting executable. Eg ``` ./exe/cactus_sim -T ``` which will output a (long) list of all compiled in thorns.
