Hello Dudu
stdlib.h is included by default via the project properties.
Right click on the project in the explorer window in CCS, then left click "Properties"
On the pop up menu, go to CCS Build -> ARM Compiler -> Include Options
See that "${CG_TOOL_ROOT}/include" is included.
If you go to back to Properties, then go to Resource -> Linked Resources, you will see that $CG_TOOL_ROOT is set to your tool installation directory
For me, this is C:\ti\ccsv8\tools\compiler\ti-cgt-arm_5.2.5
If I go to this directory via windows explorer, and then descend into the "include" directory, I find stdlib.h.
So all of the files in this directory are included for this project, via this mechanism.
Best Regards
Cormac
