TensorFlow compiles on the Nano 33 BLE Sense but not on the MKR WiFi 1010.
Yes, it's a different processor (and probably not as appropriate), but the compilation errors are simply missing macros defines, specifically __STATIC_INLINE and __STATIC_FORCEINLINE.
Board support for the WiFi 1010 includes both gcc and g++. The sketch hello_world and its subsidiary .cpp and .h files include neither of these macros. They reside deeper in the supporting code.
What is different about the language support for the two boards?
