I want to use mbedtls for my stm32 projects, but I have some problems with building. I have to build mbedtls with arm-none-gcc compiler, right? My command is :(in build directory).
CC=/home/jareeeeczek/Arczbit/Firmware/ProgramingRelated/ARM_GCC/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc CFLAGS='-fstack-protector-strong' cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On ../
and I have error while compiling test program:
none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc CFLAGS='-fstack-protector-strong' cmake -
DUSE_SHARED_MBEDTLS_LIBRARY=On ../

is not able to compile a simple test program.
It fails with the following output:

Anyone has idea why cmake has problem with compiling test program?
I think you did not configure mbedtls so that it could be built for a bare-metal system. Some default options need to be disabled, because your target is not a general purpose operating system: (no file system, so standard BSD socket interface,...).
This is the reason why you cannot compile the test programs, and why you need to disable their compilation by specifying -DENABLE_TESTING=OFF in your cmake build command.
Please refer to the numerous and useful comments in mbedtls-2.25.0/include/mbedtls/config.h in order to get more details on the various configuration options that are available.
The procedure described hereafter does work, and you should be able to modify your own build procedure by using it as a working example.
