This should probably go to ports@ but I don't belong to that. I'm running 5.2 as the latest, but 5.4 looks the same (has the same setjmp patch). There was an old problem with xnecview under OpenBSD that caused it to crash if you tried to use it on more than about 6 frequencies, but this is new since 5.0.
Run necpp on any of the samples that come with it, then try to feed to xnecview and you get a crash like this: The program 'xnecview' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 194 error_code 8 request_code 70 minor_code 0) (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.) XNECVIEW 1.35 # freq. Zr Zi SWR gain f/b phi theta --------------------------------- Run the example with a line like nec2++ -i 36dip.nec -o 36dip.out then xnecview: xnecview 36dip.nec 36dip.out It does it with my antennas too, works right under Linux.
