I had a problem with my KXStudio a kubuntu 14.04 LTS.
When I try to make start the appimage in a xterm it said that it didn’t found Gomp4.0.
The trick is that and it’s work for me, it’s seem to be a packaging problem with gcc 4.8:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g+±4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g+±4.9
It’s working now.
I wish it will be hopefully.
