Re: [cx-oracle-users] cx_Oracle on HP-UX 11.31 ia64 built with aCC successfully but failed to load

Hi I sent this one a few days ago. Did you get this? Thanks in advance for reverting. :)



===========================================================================================



This is the output of file, ldd and chart, respectively. Can you help to elaborate what does it mean by using "LD_PRELOAD"? It gives me an error when I invoke it by appending LD_PRELOAD with the path of python. LD_PRELOAD is an invalid command when I separate the two.

On Itaium you may need to invoke python as LD_PRELOAD<path to python>  and at the python prompt "import cx_Oracle"



If that fails

try  LD_PRELOAD $ORACLE_HOME/lib/libclntsh.so<path to python>  and at the python prompt 'import cx_Oracle'
