Native boards fail to link due to an upstream bug in cryptoauthlib's
test infrastructure. The file build/pkg/cryptoauthlib/test/cmd-processor.c
has incorrect conditional compilation logic:
#if defined(_WIN32) || defined(__linux__) || defined(__APPLE__)
int main(int argc, char* argv[]) { ... }
#elif defined(RIOT_APPLICATION)
int atca_run_cmd(char *command, size_t len) { ... }
#endif
On native boards, __linux__ is defined, so the code compiles a main()
function instead of atca_run_cmd(). This conflicts with RIOT's main()
and causes linker errors:
- multiple definition of 'main'
- undefined reference to 'atca_run_cmd'
On ARM boards, none of these platform macros are defined, so the code
correctly falls through to the RIOT_APPLICATION branch and compiles
atca_run_cmd() instead.
The fix would require patching cryptoauthlib to check RIOT_APPLICATION
before checking platform macros, or reporting this upstream to Microchip.
