I am trying to use the orcascript command "Build project" like shown below

start session

set debug true

build project "c:\orcatest\orcatest.pbl" "p_orcatest"

scc close
end session

In my folder "c:\orcatest\" I have the attached pbl.

I get this error:

Start Session
set debug "true"
Build Project "c:\orcatest\orcatest.pbl" "p_orcatest"
Orca error in 'buildProject'. Result Code -5.
The library list for the current Orca session must be set prior to making this request.
Last Command Failed.
End Session

Does anyone know what the problem is?
