Oscam on Qnap TS-251

Hi, I'm trying to run oscam on Qnap TS-251. I have tried few versions so far, but none of them seems to be correct, or am I missing something?

The message I'm getting is:
"./oscam: cannot execute binary file" on x86_64 version
"./oscam: error while loading shared libraries: libz.so.1: wrong ELF class: ELFCLASS32" on marv version
"./oscam: error while loading shared libraries: libpcsclite.so.1: cannot open shared object file: No such file or di rectory" on x686 version

uname -a
Linux LEXI 3.12.6 #2 SMP Sat Nov 1 00:42:26 CST 2014 x86_64 unknown

Processor: Intel Celeron 2.41GHz dual-core processor

I have tried those versions already:
oscam-svn10079-i686-webif-libusb-pcsc-Distribution.tar.gz
oscam-svn10079-x86_64-pc-linux-webif-libusb-ssl-Distribution.tar.gz
oscam-svn10081-marv-qnap-webif-libusb-Distribution.tar.gz

Many thanks

I have tried to follow the tutorial you send be but, most of the packages required are not available through Optware IPKG.

I'm stuck on the below screen:
