I've followed the readme.txt file instructions and installed it on my Kubuntu 11.4 system. When try to run the GUI, it won't load. When I call it from the command line, I get the following error message.
mandelbulber: error while loading shared libraries: libjpeg.so.8: wrong ELF class: ELFCLASS64
I've done a search for ELF errors and they all seem to date back a couple of years or more.
Please tell me whether you have 32-bit or 64-bit operating system. If you have 32-bit system, it means that you have installed wrong 64-bit version of libjpg.so.8 (it is strange but possible). To check this please type in terminal:
objdump -f /usr/lib/libjpeg.so.8
and paste here the result
