Rolauncher segfault

[Zarakaye]

Hi,
Today i does a new install and i fail to use regnum

I will show step by step what i try:

Running RO

$ LANG=C ./rolauncher 
Erreur de segmentation (core dumped)

Running RO with env var

$  LANG=C MALLOC_CHECK_=1 ./rolauncher 
Erreur de segmentation (core dumped

Running RO with gdb

$  LANG=C MALLOC_CHECK_=1  gdb -q ./rolauncher
Reading symbols from /.../...../...../regnum/rolauncher...(no debugging symbols found)...done.
(gdb) r --sync
Starting program: /.../.../.../regnum/rolauncher --sync

(gdb) quit
A debugging session is active.

    Inferior 1 [process 16170] will be killed.

Quit anyway? (y or n) y

Running Live/game directly

 $ ./game login md5EncryptedPassword &
[2] 15102

That display this




Looking for missing dependencies

 for lib in $(ldd live/game | grep -o '/lib.* '); do
    [[ ! -e $lib ]] && echo "error lib $lib not installed"
done

All linked file listed are present on my system

System

$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID:    Fedora
Description:    Fedora release 20 (Heisenbug)
Release:    20

So what can i do ?

Hi.

What version of libpng does your distro have?

The same thing here but no stack?

You can try to isntall libpng 1.2 from the AUR, but I think you will need an older version of gdk-pixbuf too as the latest version of that causes segfaults on the launcher too.

What I found helps is to place all the older libs the launcher needs into a folder "libs" in the same directory as the launcher executable, if you need the older gdk-pixbuf lib, let me know I'll stick it up somewhere for you to download.

Good luck! Here's hoping NGD shows linux some love in 2014, so we can stop tinkering to get their game that's supposedly supported on linux to work.

I might be wrong but some friends told me that the linux binaries offered by NGD for download are broken. They had no problems running the game with my binary (updated through the launcher from a game version I downloaded years ago).

I've found the cause of this issue

For developers:

$ strace ./rolauncher

***


open("/usr/share/icons/Faenza/actions/16/gtk-cancel.png", O_RDONLY) = 14
fstat(14, {st_mode=S_IFREG|0644, st_size=816, ...}) = 0
read(14, "\211PNG\r\n\32\n\0\0\0\rIHDR\0\0\0\20\0\0\0\20\10 \6\0\0\0\37\363\377"..., 65536) = 816
read(14, "", 65536) = 0
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x40} ---
+++ killed by SIGSEGV (core dumped) +++

Its all about icon and developer's mistake)))

For users solution colud be in

sudo rm /usr/share/icons/YOUR_GTK_THEME/actions/*/gtk-cancel.png

This file is symlink in Arch so don't worry

EDIT: also you can try to switch to default GNOME icon theme (for me there was no file gtk-cncel.png) After you authorize your computer via email, there should be no problems.

Yes, it depends on themes

open("/usr/share/themes/Adwaita/gtk-2.0/Entry/entry-border-fill.png", O_RDONLY|O_LARGEFILE) = 19

I use openbox and its not working, changing to kde4 is back to normal.

Maybe It is all because of symlinks. On opensuse there is no such troubles on same machine with same settings.

We don't know the code they used before the segfault, however they should use readlink to get a symlinks real path and filename before they try to open it with the open command. Opening a symlink directly by open( is clearly an error of programmation.
