PiCore Player : installing Shared libraries

Hello guys,

I am an IT guy, but on crosoft world.. even if I studied unix in school.. that was a long time ago.. be gentle with me :)
I have created an application in CPP that uses GPIO, the aim, is to turn on/off an HI-Fi triggered by the GPIO on the piCorePlayer.
My application worked fine on a Rasbian OS 32 bit using libWiring shared library.
On the first step, when i ran the application for the first time on the piCorePlayer.. the shell told me that it was not found.. I realise that my compilation was 32bits, and the piCoreplayer was 64.. I thought that 32bit application can be run on 64bit OS.. but I reinstall the piCoreplayer in 32bit.. and I had the next error : cannot find the share library libWiring.so

I have copied it into the application directory => library still not found
I have tried to copy it into /usr/local/lib => access denied
I have tried to install the package from repository = > dpkg not found
I have tried to compile staticaly the lib, but i don't have the .o of the lib, only .so

what can i do ?

I am sure i will need you for the next blocking steps :)

thx for your help
