Unable to Compile SteamSensor - SSL defines

[gseq]

I'm running the latest CSDK - 1.3.1-957. I switched the compile flags to my compiler and am having a hard time resolving the following referenced. Note that compile is all ok. It is a link time error. I've checked all the include files as well as made sure that CONFIG_SSL_ENABLE_CLIENT is set to 1 under thirdparty/axTLS.

#define CONFIG_SSL_ENABLE_CLIENT 1

This is using the SteamSensor example.

Tracing further.. it is because CONFIG_SSL_CERT_VERIFICATION is not defined. However it is defined in crypto.h through CONFIG_SSL_ENABLE_CLIENT.

/* enable features based on a 'super-set' capbaility. */

#if defined(CONFIG_SSL_FULL_MODE)

#define CONFIG_SSL_ENABLE_CLIENT

#define CONFIG_SSL_CERT_VERIFICATION

#elif defined(CONFIG_SSL_ENABLE_CLIENT)

#define CONFIG_SSL_CERT_VERIFICATION

#endif

Any help is appreciated.

The bi_XXX functions are in the AxTLS library in  crypto/bigint.c, are you sure you included that in the Makefile you created for your uClinux port?

Thanks for your help.

The issue was a compilation problem. Our app code is in g++, while TW in gcc. It compiles well now, but I have a BSD socket issue now in another ticket.
