This error is encountered when you are trying to use 32-bit iTest Enterprise GUI to connect to STC chassis when you have the 64-bit STC application installed on your system.
To fix this error first copy the libtcl8.5.so file from the STC lib folder to the /lib folder. E.g.:
cp [STC install path]/Tcl/lib/libtcl8.5.so /lib
Next, in the STC Session Profile, ensure you have the set the following properties:
- Path to Tcl interpreter: "file:[STC install path]/Tcl/bin/tclsh8.5"
- Spirent TestCenter Tcl API directory: "file:[STC install path]"
NOTE: In the above example, replace [STC install path] with the actual install path, e.g. "/opt/stc-4.50/Spirent_TestCenter_4.50/Spirent_TestCenter_Application_Linux"
