crash on Ubuntu 14.04

[drBouvierLeduc]

(v0.3.2) On Ubuntu 14.04, as soon as I click on a tab, it's an instant crash with the following error message in the terminal :

./NormalmapGenerator: symbol lookup error: ./NormalmapGenerator: undefined symbol: _ZN7QString13toUtf8_helperERKS_

Does it happen with emptpy tabs (no image loaded), too?

Did you just download the zip and start the program or did you relink the libraries (like described in this post: http://www.luxrender.net/forum/viewtopic.php?f=17&t=11058&start=20#p107983)?

What version of Qt do you have installed?

No it doesn't crash with empty tab.

The first time, I didn't relink the libraries. I jumped straight from the first post in the luxrender forums to the github page, whithout reading all the thread. If some relinking is necessary, I would expect some readme file explaining the process with the archive.

So I tried to do that, but I have a new error message :

Cannot mix incompatible Qt library (version 0x50201) with this library (version 0x50300)

I'm not very familiar with linking libraries and such, so it's very possible I did something wrong.

Here is the output from ldd command :

My version of Qt is the one that comes with Ubuntu 14.04, which is 5.2 if I'm not mistaken.

Thanks, I'll try to fix the linking issues with a wrapper script in the next days. Hopefully I can get it to a point where it runs out of the box, I'll report back here then.

Please try with this tar.gz archive: https://github.com/Theverat/NormalmapGenerator/releases/tag/v0.3.3

Start the wrapper script with ./NormalmapGenerator I tested it on a live Ubuntu 14.04.

It works fine now, thanks for your support
