… h64/include -c ../threadExample.c

../threadExample.c:118:58: error: incomplete definition of type ‘struct dbFldDes'
  118 |   printf(“ FldDes name = %s\n", dbChannelFldDes(chan)->name);
      |                                     ~~~~~~~~~~~~~~~~~~~~~^

   15 | struct dbFldDes;
      |        ^

Adding #inlcude “dbBase.h”

leads to :

...
