Hi,

I just did a fresh cvs checkout and rebuilt grass from scratch. v.digit still segfaults :frowning:

How did you run v.digit? From the GIS Manager, from the command line, both?

Jachim,

Thanks for the details. That may help someone, but doesn't help me. I just
need to know if v.digit is breaking only when opened in gis.m, whether it
doesn't work when run from the v.digit module gui, and/or whether it doesn't
work when run completely from the command line.

If it's the last, it is a problem in the C module that still needs to be
fixed; if the first, it's a GIS Manager problem; if the second, its a
problem with the module GUI.

Michael

Did you do the following:

open a display manually (d.mon start=x0)
run v.digit

The reason I ask is that there was a problem that I fixed today that
involved automatically opening an x11 display for v.digit when the digitize
button in gis.m is pushed. But this does NOT fix any problem in v.digit
itself.

I also get the following error:

Wolf,

Would you try simply running it from the command line.

D.mon x0
V.digit myexistingmap

(where myexistingmap is a vector map you already have), then try

D.mon x0
V.digit -n mynewmap

(where mynewmap is the name of a vector map that *doesn't* exist)

Thanks
Michael

Thanks. This is very helpful.

There is still something wrong with the underlying v.digit module that needs
to be looked at by the C-folks.

Wolf,

Would you try simply running it from the command line.

D.mon x0
V.digit myexistingmap

segfault:

(where myexistingmap is a vector map you already have), then try

D.mon x0
V.digit -n mynewmap

segfault

Hallo and sorry - debuging is not my cup of tea, alas.

Threaded Tcl + C is hard for anybody.

A dumb but effective method is to start adding
  printf(" -- here line 1234\n");
in the C code and
  puts {"here line 1234"}
in the tcl code and see if you can narrow down exactly where it breaks.
When you find that you can print the variables before the call to
investiatge.

gdb hints: [compile with -g and without optimization or stripping]

(gdb) bt f # outputs all variable values when it broke
(gdb) l # (lowercase "L") shows where in the source code you are
(gdb) frame 0 # switches to that function (eg #0 strlen())
(gdb) p <name> # print the value of some variable

see also doc/debugging.txt in the source code.

It's all fine for me on Debian/stable tcl/tk 8.4

Can you try compiling with tcl8.3-dev and tk8.3-dev and see if you get
the same result?
