Re: global/gtags file location error in cygwin

[Nalla R]

The problem seems to be with the pread calls in gtags. Here is a strace snip
of the stuff:

  225 1989051 [main] gtags 1812 fhandler_base::lseek: lseek
(/home/nalla/livehttpheaders/GPATH, 0, 1)
   77 1989128 [main] gtags 1812 fhandler_base::lseek: setting file pointer
to 0 (high), 0 (low)
   79 1989207 [main] gtags 1812 fhandler_base::lseek: lseek
(/home/nalla/livehttpheaders/GPATH, 0, 0)
   77 1989284 [main] gtags 1812 fhandler_base::lseek: setting file pointer
to 0 (high), 0 (low)
   89 1989373 [main] gtags 1812 fhandler_base::read: returning 8192, binary
mode
   77 1989450 [main] gtags 1812 fhandler_base::lseek: lseek
(/home/nalla/livehttpheaders/GPATH, 24, 0)
   76 1989526 [main] gtags 1812 fhandler_base::lseek: setting file pointer

   77 1989603 [main] gtags 1812 fhandler_disk_file::pread: -1 = pread
(0x66671C, 8192, 0)
   78 1989681 [main] gtags 1812 pread: -1 = pread (4, 0x66671C, 8192, 0),
errno 0
  150 1989831 [main] gtags 1812 close: close (4)
   77 1989908 [main] gtags 1812 fhandler_base::close: closing
'/home/nalla/livehttpheaders/GPATH' handle 0x2EC
  354 1990262 [main] gtags 1812 close: 0 = close (4)
  518 1990780 [main] gtags 1812 sig_send: sendsig 0x2FC, pid 1812, signal
-34, its_me 1

Compile GNU Global after disabling pread and pwrite calls. I did it by
removing the #define lines for pread and pwrite from the config.h file the
configure script generates. - Can anyone tell me a better way of doing it
from the CLI? - gtags will work fine after that.

HTH.
