crash on "copy to game directory"

[higuita]

$ ./Start\ SteaScree.sh 
./Start SteaScree.sh: line 2: 23735 Floating point exception(core dumped) LD_LIBRARY_PATH=lib ./SteaScree

This on slackware64 -current.

If i start SteaScree without the LD_LIBRRARY_PRELOAD, everythinh works file... so at very least add to the end of the shell script this:

if [ $? != 0 ]; then
  echo "SteaScree crashed, try running it directly by typing ./SteaScree"
fi

Thanks for the tool and the linux version!

Well, I didn't have any chance to test SteaScree on Slackware, thanks for heads up! LD_LIBRARY_PATH=lib makes it so system-wide Qt libraries aren't used and I don't understand from where LD_LIBRARY_PRELOAD you mentioned went. Do you mean LD_LIBRARY_PATH=lib?

[higuita]

yes, i'm talking about the LD_LIBRARY_PATH=lib (sorry i had wrongly swap PATH with PRELOAD).

something in the SteaScree lib/ is making the app crash in slackware... probably some version missmatch with other libs in the system

I have a core, so running gdb i get:

Core was generated by `./SteaScree'.

Well, as far as I understood, you just removed the LD_LIBRARY_PATH=lib, so the native Qt libraries are used instead of which were shipped in SteaScree's tarball. For some reason versions matched, obviously because you have the latest Qt installed.

Whereas it worked for you (which is good) I suppose for majority of users on popular Linux distros (such as Ubuntu and Debian) this trick will not work, since they are typically shipped with some earlier (stable) Qt libraries.

Still, as a last resort, it may be feasible to add a message when the app crashes, that probably native libraries may work, just as you suggested. I will do it in the next release.
