You must use the ported library here:
The STM32 is a 32-bit device, so libraries must be reworked a bit to be compatible.

Edit: I made a funny “reworked a bit” 
working with maple mini, where do I connect it to? Thanks
(LOL) I just checked and 7 is NSS which is PA4, so this will only work if you use a fairly recent version of the repo which has the fix for STM’s NSS feature / bug 
Setup:
NRF24 – MAPLE MINI
GND – GND
VCC – VCC
CE – 3 (PB0)
CSN – 7 (PA4)
SCK – 6 (PA5)
MOSI – 4 (PA7)
MISO – 5 (PA6)
IRQ – 1 (PB10)
Some info is from here – http://www.stm32duino.com/viewtopic.php?t=138

But still nowhere to connect CSN.. But still nowhere to connect CSN..
