XnRetro 1.26: Light effect don't work

[scx]

Hello!

I've just downloaded XnRetro (1.26) for Linux. First of all: I'm using the 32bit version on my Ubuntu 13.04 64bit machine. Unfortunately, your link to the 64bit version is broken.

The main problem: Light effects don't work. Doesn't matter which one I choose, they don't apply to the image. Also, there are no light effect previews in the bottom bar, see screenshot:



Everything else seems to work fine

I believe that this problem is related to the bundled Qt4 libs.

Try to enable Qt debug messages:

Code: Select all

export QT_DEBUG_PLUGINS=1 
export QML_IMPORT_TRACE=1

and then start the app:

Code: Select all

./xnretro.sh

You should see something like this on the console:

Code: Select all

"The plugin '/app/XnRetro/lib/imageformats/libqgif.so' uses incompatible Qt library. Expected build key "i386 linux g++-4 full-config", got "x86_64 linux g++-4 full-config""

It seems that this is an old Qt4 issue.

Build problem & won't fix for Qt 4. It's been like that since 2005, when Qt 4.0 was released.

When compiling Qt 4 on a 64-bit system, you should always run:

Code: Select all

i386 configure -platform linux-g++-32

This is fixed in Qt 5 by a complete rewrite of the Qt arch-specific code.

Anyway, I was able to fix it in my flatpak package by rebuilding Qt4 on my own.
