CCS/TM4C1294NCPDT: Building multiple projects in a workspace

Harshel
Intellectual 955 points

Part Number: TM4C1294NCPDT

Tool/software: Code Composer Studio

Hi,

I am developing embedded application on TM4C1294NCPDT and TI-RTOS using CCS v9.0.1 for development.

Case 1:

I have multiple projects in my workspace as mentioned below:

Project_Main: This is main embedded application project. This project uses library1.lib and library2.lib. Output of this project is .hex or .bin which will be flashed to microcontroller.

Project_Library1: This is library project which generates library1.lib.

Project_Library2: This is library project which generates library2.lib. This project uses library1.lib.

Project build order needs to be setup as below:

  1. Project_Library1
  2. Project_Library2
  3. Project_Main

Case 2:

I have multiple projects in my workspace as mentioned below:

Project_Main: This is main embedded application project. This project uses library1.lib and library2.lib. Output of this project is .hex or .bin which will be flashed to microcontroller.

Project_Library1: This is library project which generates library1.lib.

Project_Library2: This is library project which generates library2.lib. This project uses library1.lib. Also some configuration of this library is dependent on macros defined in "Project_Main".

Project build order needs to be setup as below:

  1. Project_Library1
  2. Project_Library2
  3. Project_Main

I need to setup my build order in CCS workspace in such a way that all independent projects should build first and then dependent project after building independent projects.

If I start compiling Project_Main first time then library project should build first and then application project. Is it possible ? To trigger compilation of one project from other project.

Please help me to resolve above cases.

Thanking you.

Best Regards,

Harshel

    Harshel,

    You can set this up using the Project Dependencies feature. It is documented in this page: 
    http://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_project-management.html#project-dependencies

    Basically for Project_Library2, you set up a dependency on Project_Library1. And for Project_Main you set up a dependency on Project_Library2.

    Hope this helps.

    Hi Arti,

    I tried case 1, it worked for me successfully.

    But for case 2, I need help.

    In case 2:

    "Project_Main" has symbol "MACRO_1" in "Predefined Symbols" in "Project Properties".

    Is it possible to make available such predefined symbol "MACRO_1" available in "Project_Library2" ? "Project_Library2" does not have same predefined symbol "MACRO_1".

    I have to make available "MACRO_1" from one project to other. Is it possible ? If possible then how can it be done ?

    You can do this (export a macro) from a dependent project to the main project that references it, but not the other way around. 

    For example, if the macro is defined in Project_Library2 and Project_Main has Project_Library2 set as a dependent project, then the macro can be exported from Project_Library2 to Project_Main, using the setting below. Note that to get to the C/C++ General settings you need to click on "Show Advanced Settings" at the bottom of the dialog.

    However, it seems that you want to do it the other way around. I don't believe that is possible.

    Thanks for reply.

     

    As it is not possible.

     

    I have one more way to do it. Please let me know feasibility.

    Consider below scenario:

    In library project "Project_Library2", below conditional compilation is exists in my code.

     

    #if defined(CONFIG_1)

    /* Configuration for CONFIG_1 */

    /* Code for CONFIG_1 */

    #elif defined(CONFIG_2)

    /* Configuration for CONFIG_2 */

    /* Code for CONFIG_2 */

    #endif

     

    In pre-defined symbols "CONFIG_1" or "CONFIG_2" are provided.

    Is their any way to compile "Project_Library2", first with "CONFIG_1" and with "CONFIG_2" ?

    And output of "<ProjectName>_CONFIG_1.lib" and "<ProjectName>_CONFIG_2.lib" respectively.

    When I compile using CCS "Build/Rebuild Project" option, with one trigger of compilation 2 different libraries should be generated with each pre-defined symbol.

    Best Regards,

    Harshel

    Yes, you can set up a library project with multiple build configurations, just like you can with executable projects.

    In your case, Project_Library2 can have two build configurations - one that defines CONFIG_1 and sets the output file name to <ProjectName>_CONFIG_1.lib, and another config that defines CONFIG_2 and sets the output file name to <ProjectName>_CONFIG_2.lib.

    More about build configurations in this page: http://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_project-management.html#build-configurations

    Hope this helps.
