How to include Crypto Library in System workbench project?

[RP]

I have Downloaded STM32CubeExpansion_Crypto_V3.1.0 library. I am trying to use it for STM32L431RBTx Microcontroller. But I am getting error as shown in following images.

What am I missing to do?Please help.

Building target:

_V0.1.elf" @"objects.list" -llibSTM32CryptographicV3.0.0_CM4_GCC_ot -lm

c:/ac6/systemworkbench/plugins/fr.ac6.mcu.externaltools.arm-none.win32_1.13.2.201705091103/tools/compiler/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -llibSTM32CryptographicV3.0.0_CM4_GCC_ot

collect2.exe: error: ld returned 1 exit status

I have also tried by removing the prefix 'lib' from library .a file name. Then I am getting following error.

Hi,

 This is a link issue, please try to use STM32CryptographicV3.0.0_CM3_GCC without "lib" in the Library name.

Regards,

Amir​

Thanks for your reply Amir. I tried that one also. but getting different error after that.

​The new issue is related to the Floating point support.

You need to use another Library built with the support of FPU:

\STM32CubeExpansion_Crypto_V3.1.0\AccHw_Crypto\STM32L4\Middlewares\ST\STM32_Crypto\Lib\libSTM32CryptographicV3.0.0_CM4_GCC_FPU.a

Thank you so much Amir for your instant reply. Support of FBU worked. Project built successfully.

​You are welcome.

Good luck for your business.

Happy to support you.
