Linking error

I recently started getting this error
test.cpp just contains a function to get revision.

You updated libspdm or have you been enabling new functionality? Those functions are all behind #defines. For example

libspdm/include/hal/library/responder/setcertlib.h

Lines 15 to 28 in 9bc6963

	#if LIBSPDM_ENABLE_CAPABILITY_SET_CERT_CAP
	/**
	* return if current code is running in a trusted environment.
	*
	* @param[in] spdm_context A pointer to the SPDM context.
	*
	* @retval true It is in a trusted environment.
	* @retval false It is not in a trusted environment.
	**/
	extern bool libspdm_is_in_trusted_environment(
	#if LIBSPDM_HAL_PASS_SPDM_CONTEXT
	void *spdm_context
	#endif
	);

Ie if you're making a Responder that supports SET_CERTIFICATE then it needs to implement libspdm_is_in_trusted_environment().

I was facing this issue when I made a Debug build , after changing it to release build its working for
libspdm_get_response_certificate
but same linking error for
libspdm_get_response_key_exchange

Is there a need to link device_secret_lib_sample library ??

[moronmonkey]

I am not actually changing or implementing any new responder functions , I want to use the default responder functions , there is no device available yet. Which all libraries I need to link ? Linking to libspdm.a , libspdm_crypto.a and libspdm_platform.a gives undefined error for
libspdm_responder_data_sign

Simplest thing to do is just cmake -DARCH=x64 -DTOOLCHAIN=GCC -DTARGET=Debug -DCRYPTO=mbedtls .. and that will include the stuff in https://github.com/DMTF/libspdm/tree/main/os_stub/spdm_device_secret_lib_sample. When/if you are ready to make a real device you will need to provide implementations for those functions.
