You probably compiled WIEN2k as a 32 bit application on a 64 bit
Ubuntu. So when it tries to load the 64 bit libfftw3.so.3, it gives
that error because it needs and cannot find the 32 bit libfftw3.so.3 [
http://askubuntu.com/questions/436802/why-do-i-get-error-while-loading-shared-libraries-libgl-so-1-wrong-elf-class
].
You might be able to solve the problem by installing the 32 bit
libraries [
http://askubuntu.com/questions/60751/is-it-possible-to-have-32-bit-libraries-installed-on-a-64-bit-system
]: sudo apt-get install ia32-libs
However, the recommended way to solve the problem would be to run
siteconfig, change the compile settings to 64 bit ones, and recompile
WIEN2k as a 64 bit application (without any compile time errors).
