I recently installed a new build of Softimage, and right from the start I was getting Debugging interfaces not available – debugging is disabled.. messages in the script history.
(Note that I use the Python installed with Softimage.)
I tracked the message down to the SetScriptSite function in
# # IActiveScript def SetScriptSite(self, site): # We should still work with an existing site (or so MSXML believes 🙂 self.scriptSite = site if self.debugManager is not None: self.debugManager.Close() import traceback try: import win32com.axdebug.axdebug # see if the core exists. import debug self.debugManager = debug.DebugManager(self) except pythoncom.com_error: # COM errors will occur if the debugger interface has never been # seen on the target system trace("Debugging interfaces not available - debugging is disabled..") self.debugManager = None except ImportError: #trace("Debugging extensions (axdebug) module does not exist - debugging is disabled..") self.debugManager = None except: traceback.print_exc() trace("*** Debugger Manager could not initialize - %s: %s" % (sys.exc_info(),sys.exc_info())) self.debugManager = None try: self.lcid = site.GetLCID() except pythoncom.com_error: self.lcid = win32api.GetUserDefaultLCID() self.Reset()
Normally (in all my other Softimage installs on this computer), line 10 fails and fires an ImportError. This is invisible because the trace() on line 19 is commented out. So basically, the Softimage install anticipates that win32com.axdebug.axdebug won’t be found.
However, if win32com.axdebug.axdebug is found, then SetScriptSite tries to import debug, and when that fails, you get that Debugging interfaces not available – debugging is disabled.. message. That’s what was happening on my machine.
As usual, my friend Process Monitor was helpful in figuring this out.
My workaround, for now, is to comment out that trace() call on line 16.
