How to create a test.out file to sue for Unity Ceedling testing framework in IAR compiler

Question

I am trying to implement Unity Ceedling test framework with IAR compiler. but the Ceedling asks for a .out file of the test but IAR produces a project out file only. How to solve this issue or create a out file for the test file with IAR.

In my tools section I give the

:test_compiler:
    :executable: IarBuild.exe
    :name: 'IAR test compiler'
    :arguments:
      - path to the project.ewp                
      - '-build'              # Command to perform a build
      - 'Build configuration name '               # The build configuration name

// This produces a .out file from this command. tried using IAR commands but showed error while running so removed it.

  :test_linker:
    :executable: ilinkarm.exe
    :name: 'IAR test linker'
    :arguments:
      - --vfe  #Very Fast Executable mode.
      - --redirect _Printf=_PrintfFull
      - --redirect _Scanf=_ScanfFull
      - --config "path to generic_cortex.icf"
      - --map "path to project.map"
      # Additional flags can be added here if needed in the future
      # - -o "path to the project.out folder"
        
  :test_fixture:
    :executable: CSpyBat.exe
    :name: 'CSpyBat test runner'
    :arguments:
      - --backend
      - simulator
      - --plugin
      - '"path to armproc.dll"'
      - '"path to jlinkarm.dll"'
      - '"path to armsim2.dll"'
      - --plugin "path to armbat.dll"

Error message : Error[Li005]: no definition for "__iar_program_start" [program entry] Fatal error[Li010]: no modules to link Fatal error detected, aborting. ERROR: Shell command failed.

Shell executed command: 'ilinkarm.exe --vfe --redirect _Printf=_PrintfFull --redirect _Scanf=_ScanfFull --config "generic_cortex.icf" --map "project_name.map"' Produced output: IAR ELF Linker V8.50.9.278/W32 for ARM Copyright 2007-2020 IAR Systems AB. And exited with status: [3].

NOTICE: If the linker reports missing symbols, the following may be to blame:

1. Test lacks #include statements corresponding to needed source files.
2. Project search paths do not contain source files corresponding to #include statements in the test.
3. Test does not #include needed mocks.

Consider changing :test_compiler: to iccarm.exe (adjusting arguments accordingly). IARBuild is the command-line build tool not compiler.

Add the following to your project.yml if not already present:

:extension:
  :executable: .out

Also here is an example Ceedling configuration using the IAR C/Cpp Compiler for RX: https://stackoverflow.com/a/77493081/22832892.
