Compiler/TMS320F28379D: How to use CCS variable in linker command file

Part Number: TMS320F28379D

Tool/software: TI C/C++ Compiler

Hello all,

For a new project I need to add some link flags in a linked command file.

Especially,  we have to add a Library path. This path is located in the workspace outside the project.

So we have add:

-l "C:/D/Workspace_CCSV8/MyWorkspace/LibProject/Debug/COMMON.lib"

It works, but it is a little bit dirty. I would like to avoid full path in this file, therefore, we have written:

-l "${workspace_loc}/LibProject/Debug/COMMON.lib"

which is not working.

So, how to add CCS8 or environment variable in linker command file?

Thanks a lot.

Alain

    Alain,

    In CCS, right-click on the project name and select properties. Under Resource-> Linked Resources, you will find all the path variables for your project. Make sure to check the path variable "workspace_loc" matches "C:/D/Workspace_CCSV8/MyWorkspace". If it does not, you will need to add a path variable with the path to your lib file. Then use that path varibale when linking the common.lib

    Let me know if you have any additional questions.

    Regards,

    Hi Ozino, I want to add

    I am aware of adding library in the project properties. I want to add library in linker command file. I need to avoid full path in this file, so, I need to use variable  in this file.

    (when using the full path it woks fine)

    Here, the line in my linker command file

    -l ${workspace_loc}/MyWorkspace/Debug\COMMON.lib

    And the result:

    Invoking: C2000 Linker

    "C:/D/ti/ccs800/ccsv8/tools/compiler/ti-cgt-c2000_18.1.1.LTS/bin/cl2000" -v28 -ml -mt --cla_support=cla1

    --float_support=fpu32 --tmu_support=tmu0 --vcu_support=vcu2 -O0 --fp_mode=relaxed --define=LAUNCHPAD -g

    --diag_warning=225 --diag_wrap=off --display_error_number -k --asm_listing --c_src_interlist

    --gen_preprocessor_listing -z -m"EQSW_COM.map" --stack_size=0x200 --warn_sections

    -i"C:/D/ti/ccs800/ccsv8/tools/compiler/ti-cgt-c2000_18.1.1.LTS/lib"

    -i"C:/D/ti/ccs800/ccsv8/tools/compiler/ti-cgt-c2000_18.1.1.LTS/include"

    --priority --reread_libs --diag_wrap=off --display_error_number --xml_link_info="EQSW_COM_linkInfo.xml" --rom_model

    -o "EQSW_COM.out" "./main/ECU_COM_main.obj" "./main/ECU_start.obj" "../_link_cmd/ECU_COM_FLASH_lnk.cmd"

    "../_link_cmd/ECU_COM_IO_lnk.cmd" "../_link_cmd/ECU_COM_lnk.cmd"  -llibc.a

    <Linking>

    error #10008-D: cannot find file "${workspace_loc}/MyWorkspace/Debug/COMMON.lib"

     

    As you can see, the variable is not resolved when used in linked command file. Is there a way to solve this issue?

     

    Thanks for your help

     

    Alain

    Alain,

    I understand your question. With regards to linking the library in the linker command file. You could try adding the .lib to your project workspace and then simply linking directly to the name i.e -l COMMON.lib. This should work.
