floating point exception.

[johngalt01]

on the 0.17rc i used the binaries elinks-0.17.0rc1-armhf-bin.tar.xz i keep getting a floating point error for both elinks and elinks-lite.
i don't know what dependency it might be.

sorry floating point exception.

maybe its my conf file i copied into config.

i just tested elinks 0.16.1 and it works fine

I checked it on rpi zero and it worked. Do you have ~/.config/elinks/hooks.lua ? If yes, rename this file.
How to reproduce this error?

[johngalt01]

if it helps I'm not running in xwindows.

I'm running via a remote telnet session.

I will check for the ~/.config/elinks/hooks.lua file.

0.16 has been a vast improvement over 0.13 :-)

[rkd77]

I'm running it via ssh. May I know what machine it is? It "fails" on startup or viewing some documents, or what?

[johngalt01]

sure some more information:

its a raspberry pi 4, it appears to open fine if I'm inside xwindows and launch a terminal session.
if i'm telneting into the machine and try to start from the command line it gives the floating point exception message and drops back to the prompt. the previous version of 0.16.1 (not .16.1.1 no binary) works no problem.

@johngalt01 On rpi zero 2, started telnetd and telnet to rpi. No error. Could you show your elinks.conf, name of terminal, and size (cols, rows)?

[johngalt01]

actually i have it on my github, its a carry over from 0.13

the terminal is set to that Xterm-256 if i remember have to look at my bash configuration.

i have it inside my readme.
https://github.com/johngalt01/johngalt01.github.io/blob/main/README.TXT

my terminal is set to
LINES to 48
and
COLUMNS to 83

[johngalt01]

this is interesting.

If i login via teraterm i can launch 0.17 over telnet
if i login via my terminal over modem i get the floating point exception

changing the Lines and Columns has no effect on the error over the terminal.
term is set to xterm-color.

no hooks.lua file.

no issues with version 0.16.1

[johngalt01]

i've been playing with 0.16.1 all evening but i wanted to see if i run 0.17 elinks --help and it will display the help menu and not crash.
is there a log option i can trigger from the command line?

for 0.17
elinks -terminfo 0 gives the Floating point exception.
-always-load-config 0 also errors.
-no-home 0 also errors.

#include <sys/ioctl.h>

	struct winsize ws;

	if (ioctl(fd, TIOCGWINSZ, &ws) != -1) {

{
	int fd;

	for (fd = 0; fd < 6; fd++) {
		get_terminal_size(fd);
	}

	return 0;
}

@johngalt01 Could you copy this code, compile and run it? It displays terminal sizes for first 6 descriptors.
Save as term_size.c
Compile: gcc -o term_size term_size.c
And run as ./term_size
You can check it for various terminals. Please show results for telnet's one.
Terminal code is suspected.

[johngalt01]

will report back.

[johngalt01]

ok cool i see the problem. What do i need to fix it?

Here are the results:

Run from inside Xwindows on terminal

fd=0 ws.ws_col=84 ws.ws_row=46 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=1 ws.ws_col=84 ws.ws_row=46 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=2 ws.ws_col=84 ws.ws_row=46 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=3 ioctl = -1
fd=4 ioctl = -1
fd=5 ioctl = -1

run from Teraterm on my PC over telnet

fd=0 ws.ws_col=80 ws.ws_row=24 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=1 ws.ws_col=80 ws.ws_row=24 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=2 ws.ws_col=80 ws.ws_row=24 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=3 ioctl = -1
fd=4 ioctl = -1
fd=5 ioctl = -1

run from the terminal that gives the Floating point exception

fd=0 ws.ws_col=0 ws.ws_row=0 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=1 ws.ws_col=0 ws.ws_row=0 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=2 ws.ws_col=0 ws.ws_row=0 ws.ws_xpixel=0 ws.ws_ypixel=0
fd=3 ioctl = -1
fd=4 ioctl = -1
fd=5 ioctl = -1

If I echo $LINES and $COLUMNS on the terminal it shows the correct 46 and 84 i have set.

[johngalt01]

if i run
eval 'resize'

on the terminal then rerun term_size i get the correct numbers in place of the zeros and elinks 0.17 starts up and runs

so i added it to my bash initialization scripts.

[rkd77]

OK. Thanks. I'm going to release on Sunday rc2 with this ^ commit.
