Create iPuissance_4D

I wonder if it works for OpenGL / SDL 1.2 application:

NUMBER_OF_WINDOWS: 0
ERROR: Could not find a single window on screen :-(

However from the log (Entered SplashScreen state.) it did create the window it seems.

Is there anything I can do to get an idea of the issue here?

Thanks for submitting.

Probably the test fails due to the test server being headless (no GPU)? See the worker.sh script to understand how the test works.

I did this locally:

$ Xvfb :99 -screen 0 800x600x24 &
$ DISPLAY=:99 ./iPuissance_4D-x86_64.AooImage
$ DISPLAY=:99 xwininfo -tree -root | grep 0x | grep '": ("' | sed -e 's/^[[:space:]]*//'
0x20000e "iPuissance 4D": ("iPuissance4D" "iPuissance4D")  800x600+0+0  +0+0
$ DISPLAY=:99 xwininfo -tree -root | grep 0x | grep '": ("' | sed -e 's/^[[:space:]]*//' | wc -l
1
$ DISPLAY=:99 xwd -root -silent | convert xwd:- png:/tmp/screenshot.png

All worked especially the window count. I didn't run on Ubuntu Xenial though.

sudo docker run --rm -it -v $PWD:/mnt:ro ubuntu:xenial
apt update
apt-get -qq -y install libasound2-dev alsa-utils alsa-oss libjack0 desktop-file-utils xmlstarlet xterm xvfb icewm x11-utils x11-apps netpbm xdotool libgl1-mesa-dri libgl1-mesa-dev mesa-utils libosmesa6 libsdl1.2-dev fonts-wqy-microhei libfile-mimeinfo-perl 
export DISPLAY=:99
Xvfb $DISPLAY -screen 0 800x600x24 &
cd /tmp
/mnt/iPuissance_4D-x86_64.AppImage --appimage-extract
cd squashfs-root
./AppRun

It outputs:

...
Entered SplashScreen state.
Segmentation fault (core dumped)

Visibly due to libexpat:

Stack trace of thread 24597:

The linuxdeploy tool didn't add `libexpat.so` to the AppImage.

What I find more weird is that installing `libexpat1` which creates `/lib/x86_64-linux-gnu/libexpat.so.1.6.0`, does not fix the issue.

The linuxdeploy tool didn't add libexpat.so to the AppImage.

Is libexpat.so opened using dl_open()?
If you suspect a bug in linuxdeploy, then please post it over at https://github.com/linuxdeploy/linuxdeploy, thanks.

I added libpcre as present in my build system and it still fails with the same error.

Tried the same on debian:jessie, it gives again the same error.
Tried the same on ubuntu:bionic, it gives a similar error but against /lib/x86_64-linux-gnu/libexpat.so.1.6.7.

Note that I build on debian:jessie (oldoldstable).

It seems as if the error is due in some other dependency. I could try to remove the dependency to XML (which was a horrible idea anyway) but that would require quite some work.

[probonopd]

Actually libexpat.so.1 is on the excludelist because we think that every target system (distribution) ships it by default.

https://github.com/AppImage/pkg2appimage/blob/d8117501942f2b4780bac0de551fc431d5901562/excludelist#L128

On which system is this not the case?

[wernight]

Tries a test version that doesn't use expat, and coredump shows:

#0  0x00007ff383940438 n/a (/lib/x86_64-linux-gnu/libc-2.23.so + 0x35438)

So it's visibly an issue when running in Docker for some reason.

[wernight]

Aha!. No my bad, it is really EXPAT that fails. I'll try to remove it.

[probonopd]

Thank you very much. It worked 👍
