RTEMS | Build system fails when switching configuration between SMP and non-SMP (#5482)

Sat Feb 7 15:49:00 UTC 2026

Kinsey Moore created an issue: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5482

## Summary
If a BSP is built without SMP enabled, config.ini altered to enable SMP, `./waf configure` run, and then `./waf` issued again, the build will produce linker errors. This can be seen with x86_64/amd64 and aarch64/zynqmp_apu and likely any other BSP that supports SMP.

This implies that there is some kind of failure to detect the dependencies that would require regeneration of the some of the object files.
