I have installed the arrowkdb library, and use it to load parquet files in KDB. My $QHOME directory now contains:

├── kc.lic
├── arrowkdb.q 
├── l64
│   ├──arrowkdb.so
│   └── q
└── q.k

But when use l to load arrowkdb.q, it raised following errors:

evaluation error:

libarrow.so.900: cannot open shared object file: No such file or directory

  [3]  /home/jiahe/q/arrowkdb.q:5: dt.na:`arrowkdb 2:(`null;1);
                                                   ^

  [0]  l arrowkdb.q
       ^

So far checked:

1. The module works well when start from console:

~/q$ q arrowkdb.q

2. I can load other q-scripts in $QHOME with l in the notebook:

I am new to KDB and also know little about Apache Arrow. Thank you very much for any suggestions:)
