Dear Andrew,
Did you happen to use this define _USE_32BIT_TIME_T?
Hope it helps,
Maurizio

Subject: [naviserver-devel] Naviserver hangs on Windows
With my changes here, the core Naviserver compiles now on my Windows 7
64-bit machine:
https://bitbucket.org/naviserver/naviserver/pull-requests
https://bitbucket.org/apiskors/naviserver/commits/all
However, it doesn't work at all. If I simply run "nsd -h", it hangs
indefinitely, and locks up the Command Prompt window where I ran nsd.
Control-c does not abort, I have to close the window.
Note that I built Naviserver using ActiveTcl 8.5, I did not compile Tcl
myself.
I just started learning to use the WinDbg debugger. Below is a stack trace.
This one is from attaching WinDbg to an already-running "nsd.exe -h"
process, but it looks the same if I intead tell WinDbg to run nsd.exe itself
(with no command line arguments) .
>From the stack trace, Naviserver seems to be getting stuck when
Ns_GetTime (line 69 of time.c) calls TclpGetDate. But, line 69 does not
explicitly call TclpGetDate, it justs manipulates a Tcl_Time tbuf structure
like so:
timePtr->sec = tbuf.sec;
In Tcl 8.5.x, TclpGetDate is in win/tclWinTime.c, but the string
"TclpGetDate" does not occur anywhere in the Naviserver code, so I'm not
sure how it manages to call it. A function pointer somewhere?
Any ideas what might be wrong here, or what else I should do to debug this
further?
Here the initial WinDbg output when attaching to a running "nsd.exe -h"
process, and then the stack trace (the "k" command):
