Sigil segmentation fault (`core' generated)

[ramsaa]

When I try to open Sigil on Ubuntu 12.04, it appears:

Debug: loaded the dummy plugin 
Debug: loaded the Linux plugin
Segmentation fault (`core' generated)

Any idea?

Were there no errors while compiling? Do you have Qt5 installed?

What class of CPU does your system have? If I remember correctly, the SSE2 instruction set is required.

I think if you do a cat /proc/cpuinfo you can tell from the flags field if you have SSE2 available or not.

[ramsaa]

I didn't have erros and I installed Qt5...

sse2 and even sse4a are both mentioned. This is a fairly new processor and should not have the sse2 problem. Something else is the problem.

I'd always get segfaults like that whenever the binary couldn't access/find the necessary Qt libraries. That's why you have to create the special launch script that adds the Qt5 libs to the LD_LIBRARY_PATH environment variable before starting Sigil.

And just to illustrtate that thought, here's the startup script I use (which isn't my original. I probably got it from DiapDealer or meme in the first place). It also probably isn't the only way to do it.

#!/bin/sh
## point library path and QT plugin path to Qt5 files
## for sigil Qt5 version(s).
##
## NB execute /usr/local/bin/sigil.sh instead of 
##    /usr/local/bin/sigil

# Entry point for Sigil on Unix systems.
# Adds the directory the Sigil executable is located
# in to the LD_LIBRARY_PATH so the custom Qt libs
# are recognized and loaded.

dirname="/opt/Qt5.0.2/5.0.2/gcc/lib/"

if [ -z "$LD_LIBRARY_PATH" ]; then
  LD_LIBRARY_PATH="$dirname"
else
  LD_LIBRARY_PATH="$dirname:$LD_LIBRARY_PATH"
fi

export LD_LIBRARY_PATH

## not sure if the following is necessary.  But it doesn't hurt.

QT_PLUGIN_PATH="/opt/Qt5.0.2/5.0.2/gcc/lib/cmake/" 
 export QT_PLUGIN_PATH

exec /usr/local/bin/sigil "$@"

Instead of starting sigil directly, you execute sigil.sh instead.

And of course, the absolute paths mentioned may be different on your system. "Take notice and govern yourself accordingly."

Well, I try to understand but I couldn't, can you explain me again?
What I have to do, step by step...

[PeterT]

Step 1: Install Windows
Step 2: Install Sigil

[DiapDealer]

I actually think that might be best in this instance.

[ramsaa]

Well I had to installed with wine. It's working well, but I would prefer the native install on Ubuntu...

[DiapDealer]

Unofficial binary deb packages

[ramsaa]

It didn't work, I got the same error.

Must be something unique to your system.
I've installed and used the binaries successfully on systems from 11.10 forward (as have others). With Gnome, KDE, or what-have-you.

Sorry you have to go the Wine route, but without more to go on... *shrugs*
