App can't find libs even though they exist [duplicate]

Question

I'm trying to launch an application (lets call it test), but it fails giving the following error:

./test
./test: error while loading shared libraries: libuuid.so.1: cannot open shared object file: No such file or directory

Although this library does exist:

locate libuuid.so.1
/lib/x86_64-linux-gnu/libuuid.so.1
/lib/x86_64-linux-gnu/libuuid.so.1.3.0

It also can be found when using sudo ldconfig -v under the same folder.

Running ldd on the app gives the following info:

libXdmcp.so.6 => /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xf6d1c000)

So I'm missing 3 libraries in total, although all of them can be found using locate or sudo ldconfig -v.

I've tried using sudo ldconfig, and it did not change anything. I've also tried setting LD_LIBRARY_PATH to the directory of library.

I am almost sure that you get this error because you try to run a 32-bit (libX11.so.6 => /usr/lib/i386-linux-gnu/libX11.so.6) executable on a 64-bit (/lib/x86_64-linux-gnu/libuuid.so.1) operating system. Run file test to check this. Thus, the following Q&A may help you:
