FAQ: How to build for 2 cpu's?

[skliper]

Within cfe/cmake/sample_defs (that the setup steps have you copy to the top level) the default targets.cmake is just set up to build for cpu1. How do you build for more than one CPU?

Capturing the topic from the community email (thanks Gary!). This is how you add cpu2 to the build:

git clone --recurse-submodules https://github.com/nasa/cFS.git 
cd cFS/
cp cfe/cmake/Makefile.sample  Makefile
cp -r cfe/cmake/sample_defs/ sample_defs
cp sample_defs/cpu1_cfe_es_startup.scr sample_defs/cpu2_cfe_es_startup.scr 
cp sample_defs/cpu1_msgids.h sample_defs/cpu2_msgids.h 
cp sample_defs/cpu1_platform_cfg.h sample_defs/cpu2_platform_cfg.h 

vi sample_defs/targets.cmake
< change > SET(MISSION_CPUNAMES cpu1 cpu2)
 
make SIMULATION=native install
