[Therion] extended section

[marco corvi]

hi, 

i have a question.

i have a loop to adjust,
if i do not equate stations in extended section there is 
an altitude gap between them. of course therion does not know
they are at the same altitude (or depth).
if i equate, the drawing is awfully distorted because therion
tries to draw them at the same point.

is there a way to tell therion that two stations are at the same
altitude (depth) ? (but to draw them separately).

thanks, marco

Stock kernel from Debian 2.6.18-3-686. I haven't compiled my own.

[Therion] loch crash. [was usr/bin/ld: cannot find -lvtkjpeg]

[Michael Lake]

Hi all

It's a while since the last email where loch was failing with: 
loch$ ./loch 
The program 'loch' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
  (Details: serial 24 error_code 155 request_code 143 minor_code 5)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
loch$ 

Philip Schuchardt asked:

It's an Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics
Controller on a Dell Inspiron 620 laptop.

OK I have done that. at the (gdb) prompt I type run and I get... 

(no debugging symbols found)

Program exited with code 01.

I haven't used gdb before so I'll need some guidance on helping here.

Also I have installed therion-viewer_0.5.0-1_i386.deb from Wookies site.
It also crashes with the same error.
