gEDA-dev: Pcb dxf hid

[Bert Timmerman]

Hi all,

I'm kind of stuck with a small problem with the dxf hid.

It's compiling with a couple of warnings of unused variables.

The problem lies after the dxf_do_export function is exited and the way I
read the back-trace it has something to do with ghid_dialog_print.

See attached stderr log file (exerpt follows).

BTW: For debugging purposes I printed to stderr on entering and leaving
functions.

If the dxf.c (47k)and stderr.log.gz (1.1k) is needed please reply so.

TIA and kind regards,

Bert Timmerman.
