Error while linking: reference to symbol in discarded location not allowed

Hi all,

I'm trying to build a CCSv5.1 project using a tx.a library ( I read that CCS supports .a files), but I get the following error:

fatal error #10232: relocation type "R_ARM_ABS32" in file "tx.a<tx_timer_create.o>" at offset 0x00000014 in section .iar.debug_line" references symbol ".debug_info18" in discarded section with id (18); references to this symbol from this location are not allowed

The file is used with IAR tools, will it work for CCS as well?

    Jasmeet,

    What options, if any, were used when building the library with IAR tools? I may need to get some help on this one, but can you attach the library file (tx.a) here for us to take a look at?

    What is the CCSv5 command line seen in the build console for the linking step? Please cut and paste it here so we can see the full set of options.

    The library tx.a was used with some other project in IAR tools, I'm not allowed to share the library file, sorry.

    The build console for linking step is pasted below:

    I also tried to build a demo project with the same library in ARM RVDS tools, it gives me a similar error (but for a different object file)

    Here's the build console for that:

    make: *** [cortex_demo.axf] Error 1

    make: Target `main-build' not remade because of errors.

    Build complete for project cortex_demo

    Jasmeet,

    Since the linker fails in a similar manner with the ARM toolset as well, I suspect it has something to do with the way the library was created. I am not very familiar with the IAR tools, but maybe you can try to contact IAR and try to get their comments on what might trigger these types of messages. I'll also try to see if others here have any further ideas on this.

    My guess is that the library is somehow corrupted.  Try extracting all of the library files from the archive and linking with those instead of the library.  If you get the same error, you know that one of the object files is corrupted, and you can focus on that file.  If you don't get the same error, something went wrong when building the library, which would be a problem with whatever toolset was used to create the library.
