However, on this system, I couldn't recreate the problem you reported with either the "using tkinter directly" instructions, or using this "C" test program:
#include <tcl.h> #include <tk.h> int main(void) { TclInterp *trp; unsetenv("DISPLAY"); trp = TclCreateInterp(); printf("%d\n", TkInit(trp)); printf("%d\n", TkInit(trp)); return 0; }
The problem only occurs when Tcl and Tk were compiled with --enable-threads, and it occurs because Tk fails to unlock a mutex in a few error cases. The patch below fixes the problem.
I'll report it to the Tcl people, and see whether I can work around in _tkinter.
