Invalid command name "::tcl::tm::UnknownHandler"

[mibravoh]

Hi everyone,

I'm using the new compiled OpenSees 3.6.0 64-bit for Windows and when trying to use Tcllib via "package require ..." I get this error:

Invalid command name "::tcl::tm::UnknownHandler"

Even if I point OpenSees to the right place where local libraries are trough auto_path, still does not work. Do I need to build OpenSees to solve this or is there a way around it using the compiled version?

Many thanks for your help
Miguel
