Hi, I am building with the --enable-smp option. But RTEMS_SMP is not getting defined. I have referred to the configure files of other BSPs which includes the script for --enable-smp option and changed the configure script for raspberry pi. What can be the reason, I am unable to understand what I am missing.
Thanks.
