Trying to use tcl threads on windows 7 results in access violation.

Answer 1

I ended up compiling a debuggable version of Tcl. The issue is that you need to call TclInitSubsystems to initialize all the locks required for thread creation. Unfortunately, this isn't publically accessible, and an intepreter needs to be created with Tcl_CreateInterp. This was a test program for an application I was developing that has a Tcl interpreter, so it will not be an issue in production. I just need to create an interpreter for this simple test program.

Answer 2

TclInitSubsystems is called when you call Tcl_FindExecutable(), which is public. If you don't have the executable name to hand, just pass NULL there.
