CCS/CC1352R: C++ with simplelink 3.30 SDK

Hi, using project "sensor_CC1352R1_LAUNCHXL_tirtos_ccs_syscfg" with SimpleLink SDK 3.30.0.03, I have renamed main.c to main.cpp.

A first problem comes up with the compiler. The hal_types.h files defines bool without a c++ safeguared. Fixed with:

#ifndef __cplusplus
#define bool _Bool
#endif

But the linker fails with the following:

<Linking>
 
 undefined        first referenced                                                                          
  symbol              in file                                                                               
 ---------        ----------------

error #10234-D: unresolved symbols remain

What can I do to use C++ from main?

Hi mh,

I assume Main_excHandler() and halAssertHandler() are defined in main.cpp.

Have you remembered to mark those functions as extern "C"? If not, then they will be name mangled and the rest of the system will not be able to correctly link them (as you can see by the linker error).

extern "C" void Main_excHandler(...)
{
}

extern "C" void halAssertHandler(...)
{
}

Hi - can I make a request for a fix for this in upcoming SDKs?
