How do I fix a compile error in the STM32 Cryptographic Library v2.0.6

[Rook.Malcolm]

I have started to use the STM32 Cryptographic library on an existing product which uses the STM32L476 and consequently has no hardware encryption available. I have a problem when the firmware compiles. I get an error 'Undefined Symbol RCC_AHBPeriphClockCmd (referred from crypto.o)'. As the libraries are supplied precompiled, how can I fix this? I do note that there is no mention of STM32L4XX devices in the crypto.h or config.h files or templates for STM32L4xx devices.

It is trying to enable the CRC Peripheral, if the mechanics there work on the L4 you just need to make a shim/wedge function called RCC_AHBPeriphClockCmd() to enable the CRC Clock and give the linker closure.
