Problem: Fatal Error: Reference to unresolvable symbol "__pthread_once"
Running the following syntax at the UNIX prompt:
sderaster -o describe -l lake_wilson,image
-i <port> -u <user> -p <password>
will yield the resulting error when using ArcSDE 8.1.1:
Connecting to server hiccup.esri.com, port 5151, as user test
154801:/hiccup1/sde/sde81/ora816/sdeexe81/bin/sderaster: /sbin/loader: Fatal Error: Reference to unresolvable symbol "__pthread_once" in "/hiccup1/sde/sde81/ora816/sdeexe81/lib/libsde81.so"
This is a known issue.
Solution or Workaround
There is no workaround for this problem within version 8.1.1, however, this has been fixed with ArcSDE 8.1.2. It is recommended to upgrade to version 8.1.2.
