--relocatable linker option

DG44

Hi all,

I am trying to build a project using the --relocatable option, on CCSv5.3. The summary of flags set on the project properties for the C2000 linker is:

-v28 -ml -mt --cla_support=cla0 --float_support=fpu32 --vcu_support=vcu0 -g --diag_warning=225 -k --asm_listing -z --stack_size=0x300 -m"project.map" --warn_sections -i"C:/User/ccsv5/tools/compiler/c2000_6.1.0/lib" -i"C:/User/ccsv5/tools/compiler/c2000_6.1.0/include" -i"C:/Project/include" --reread_libs --priority --define=CLA_SCRATCHPAD_SIZE=0x100 --xml_link_info="C:/Project/Debug/PProject .xml" --relocatable --entry_point=code_start --rom_model

But the build process stops with the message:

"error: errors encountered during linking; "PEBB1_CellController.out" not built"

And the errors are all of type "program will not fit into", many of those on the F2806x_Headers_nonBIOS.cmd

What is needed to have the -relocatable option working ?

Thank you very much for your attention.

I'm pretty sure you are experiencing the problem described here.

Thanks and regards,

Hi George,

Thank you for your answer, but the link didn't help me. I don't get any linker error if a build the project without the --relocatable option, but the error happens with the same command files just by adding the --relocatable option. Is there anything else I should do to use this option ?

Sorry, I didn't mention that my intention on using this option is to have something similar to the Dynamic Linking explained on the following link: http://processors.wiki.ti.com/index.php/C6000_Dynamic_Linking

Do you think it is possible to implement a similar funcionality for the C2000 ?

Thank you for your attention.

It's possible, but most likely impractical unless/until the C2000 toolchain switches to ELF. You can do a lot of what dynamic linking gives you if you can generate position-independent code (PIC), but the C2000 compiler doesn't support that, either.

Thank you for your answer, which prevents me from trying something not pratical !
