@SteveBronder - just to check something with Pathfinder and inits - when multiple init files are present (one for each path), is it normal for the output to only show...

If the build/installation error is coming from the TBB, you can instead set `cmdstan` to use the libraries and headers from the `RcppParallel` package: ```r library(cmdstanr) cmdstan_make_local(cpp_options = list( TBB_INC=system.file("include",...

You can change the directory where executables are stored using the `output_dir` argument. As for the admin privileges, it can differ by organisation. Some organisations will only allow a executing...
