Yocto Warrior Bitbake Recipe for PyTorch for NVIDIA Jetson Nano

root-cause of the problem is

if (NOT INTERN_BUILD_MOBILE)  # ---[ Check that our programs run.  This is different from the native CMake  # compiler check, which just tests if the program compiles and links.  This is  # important because with ASAN you might need to help the compiled library find  # some dynamic libraries.  cmake_push_check_state(RESET)  CHECK_C_SOURCE_RUNS("  int main() { return 0; }  " COMPILER_WORKS)  if (NOT COMPILER_WORKS)    # Force cmake to retest next time around    unset(COMPILER_WORKS CACHE)    message(FATAL_ERROR        "Could not run a simple program built with your compiler. "        "If you are trying to use -fsanitize=address, make sure "        "libasan is properly installed on your system (you can confirm "        "if the problem is this by attempting to build and run a "        "small program.)")  endif()  cmake_pop_check_state()endif()

this is running program compiled.but we are cross compiling here.can you try setting INTERN_BUILD_MOBILE

set(INTERN_BUILD_MOBILE ON)

I don't have direct source which will build on jetson-nanobut following is close may help progressing.you can refer to this pull request for cross-compiling for android.

Happy to answer anything else you may need.
