Re: Building 1.3.22 from src (WAS: Re: (1.3.22) mount: strange 15 second delay)



You need to put mingw in winsup/ and then compile. Check out mails around 11th April in the mailing list Vishal

I straced it (and the problem went away) so, I straced 'bash -c mount' and the problem came back. The relavent portion of the strace is:

The 'writev' takes 11.2 seconds to complete. Could somebody give me a hint what is going on here?

The timestamp isn't time to complete. It's time since last timestamp. So something between fstat and writev took 11282054 microseconds.

Ok, I recompiled the mount.exe program with -ggdb. The delay was in on line 382. The last call to getmntent (the one that returns NULL) is the one that takes > 10 seconds.


Was hoping that this would spark a thought in someone. I'll start trying to get a debug cygwin load building to test further.
I tried to build cygwin. Ran into problems:
