core dump

roger64 · 11-09-2017, 04:46 AM

Hi

I installed the latest Sigil as an Arch package on my brand new computer to get this short statement:

[CODE][roger@lenovo ~]$ sigil
Debug: using qt5ct plugin
Warning: libpng warning: iCCP: known incorrect sRGB profile
Warning: libpng warning: iCCP: known incorrect sRGB profile
Debug: D-Bus system tray: no
Debug: D-Bus global menu: no
*** Error in `/usr/lib/sigil/sigil': free(): invalid pointer: 0x00007f482ef303c0 ***
Abandon (core dumped)
[roger@lenovo ~]$[CODE]

Previously I had added some files (mostly plugins) from my former Sigil in /home/roger/.local.

It's also fairly possible some software could not be installed yet...

I've not tried the community Arch Sigil package in a while. Did you try launching Sigil before copying your prefs from your old installation?

roger64 · 11-09-2017, 07:06 AM

No I did not. I shall take them out to check.

No change: core dump all the same

I shall see what happens with the new version just announced

My home-built Sigil version runs fine on my Arch Linux machine.

I also got:

Code:

Warning: libpng warning: iCCP: known incorrect sRGB profile

but I didn't get:

Code:

Debug: using qt5ct plugin
Debug: D-Bus system tray: no
Debug: D-Bus global menu: no

@DiapDealer: Doesn't the Debug: prefix mean that the Arch Linux Sigil packager (incorrectly) used the command line parameter for debug builds?

@roger64: Maybe your system isn't up-to-date. Enter the following command in a terminal window and then reboot your machine:

Code:

sudo pacman -Syu

If you still can't run Sigil try renaming:

Code:

/home/roger/.local./share/sigil-ebook/sigil/sigil.ini

to

Code:

/home/roger/.local./share/sigil-ebook/sigil/sigil.bak

I think Roger installed the community version (pacman -S sigil).

I honestly don't know. I get those debug messages on my custom built Sigil, as well (and some other Qt apps). They're coming from the system-supplied Qt5 and its plugin.

As far as the original error message goes, I have experienced those kinds of segfaults when config files could not be read (be it from permissions problems or non-existence).

(except the warning for the new version)

What is the new warning?

AFAIK, there are two Arch Linux Sigil packages, sigil and sigil-git.

What you could try is uninstall whatever package you've installed and then install the other one.
I.e., if you installed sigil, uninstall it and then install sigil-git.

IIRC, you'll need to use yaourt to install sigil-git:

Code:

yaourt -S sigil-git

(If yaourt isn't installed, you'll need to install it first.)

Also simply launching sigil via gdb and running doing a backtrace after the crash/abort would certainly help us to see what might be going on. It should be an easy add to the script that launches sigil after setting the right environment variables.

If not, we could/should add a command line switch to the sigil launch script to enable running it through gdb just to make bug reports from Linux users easier to get given the huge number of different Linux variants.

What do you think?

DiapDealer · 11-09-2017, 09:51 AM

I think we'd have to manually set the environment variables in a shell and launch /usr/lib/sigil/sigil via gdb manually. It may have changed, but at one time, gdb only worked with binary executables. So running the launch script (/usr/bin/sigil) with gdb didn't work.

I'll install a clean instance of Sigil with pacman on Arch later today and see if there's any problems. I've experienced some issues with that community-supplied package before in the past.

KevinH · 11-09-2017, 10:37 AM

I was thinking maybe we should be adding a command line option to the /usr/bin/sigil shell script to force it to launch sigil within gdb instead of just sigil. I do this on my own linux scripts on my research box to set the appropriate LD_LIBRARY_PATH, and set any other environment variables as normal in the script and then do:

gdb PATH_TO_REAL_EXECUTABLE/sigil

instead of just launching the real sigil executable itself.

My 2 cents ...

DiapDealer · 11-09-2017, 10:45 AM

Yes, that would probably work. We could even provide a separate debug launch-script. We'd just have to make sure to configure it with cmake, so the paths were sure to match the build/install.

DiapDealer · 11-09-2017, 02:37 PM

Sorry. I'm not much help. The Arch community package for Sigil 0.9.8 works fine for me--both as a clean install and when copying a previous config to the new installation (although it reports itself as v0.9.7 because of a tagging issue we had at release time).

If you'd like to do a little debugging, run the attached script (make it executable if necessary) from a terminal to launch sigil via gdb. Once you see the (gdb) prompt type 'run' (without the quotes, of course) followed by enter.

I've had to zip the script because Mobileread doesn't like any of the file extensions I've tried. You'll need to unzip it. You can run it from your home directory.

NOTE: the script will only work for the version of Sigil installed by pacman into the standard /usr prefix.

DiapDealer · 11-09-2017, 05:16 PM

By the way ... for those following along, the debug messages are from having the qt5ct package installed. The qt5ct package provides a DE independent Qt5 QPA and a configuration utility. which allows you to set custom colors, icon sets, fonts and themes for your Qt5 applications.

roger64 · 11-09-2017, 06:38 PM

Here it is

I had to install gdb

When you get to that point (after the crash) type 'bt' followed by enter. That should give us a bit of a backtrace.
