Porting uvisor, undefined __uvisor_priv_sys_irq_hooks

Mbed OS

I’m trying to port the new uVisor to my board, i just modified the linker script and the the statup, the configuration remain the same as i’ve already ported the last version (mbed OS 3.0 uvisor). But when i compile the whole program, i’m getting this error : undefined reference to `__uvisor_priv_sys_irq_hooks’ :

I tried building for the K64F target and got the same error

Now it’s building, actually we must add these lines in the main :

extern "C" void SVC_Handler(void);
extern "C" void PendSV_Handler(void);
extern "C" void SysTick_Handler(void);
UVISOR_SET_PRIV_SYS_IRQ_HOOKS(SVC_Handler, PendSV_Handler, SysTick_Handler);

Do we have to change all our NVIC_VECTOR functions into vIRQ_ ones ?
