cpu2 commented out in targets.cmake, but prep build still requires cpu2_PROCESSORID

[RR-HSz]

Hi,

I'm trying to build cFS and noticed the following section in sample_defs/targets.cmake:

# Skip cpu2 on the pc686_rtems5 configuration, as it becomes a resource drain
# (the images on this configuration are much larger)
if (NOT SIMULATION STREQUAL "i686-rtems5")
    list(APPEND MISSION_CPUNAMES cpu2)
endif ()

This suggests that cpu2 is optional in some configurations.

In my setup, I only want to build a single CPU. The cpu2 configuration block is commented out in targets.cmake, and MISSION_CPUNAMES contains only cpu1.

However, when running the prep build goal, CMake reports:

CMake Error at cmake/target/CMakeLists.txt:21 (message):
cpu2_PROCESSORID must be defined to link a final exe

My expectation was that if cpu2 is not included in MISSION_CPUNAMES, the build system would not require any cpu2_* definitions.

Am I missing an additional configuration step, or is this unexpected behavior? Could someone explain why the build system is still looking for cpu2_PROCESSORID when cpu2 is disabled?

Thanks!

I think if you comment out this it'll stop happening:

if (NOT SIMULATION STREQUAL "i686-rtems5")
    list(APPEND MISSION_CPUNAMES cpu2)
endif ()

You may need to do a make distclean.
