Trying to compile FreeRTOS blinky with GNU Toolchain on Hercules Launchpad

Hi Martin,

The answer is probably staring right at me in the information you included,  but I'm not 'seeing' it.  :( 

You might try dumping the symbols with the 'readelf' utility and looking for the duplicates.

The other thing to check might be what is the full linker command line given.  Are their either duplications of the .o files or is there something funny on the command line that makes the linker read the .o files multiple times.

Can you link the .o files manually without CCS?  You know just call the linker from a command prompt and give it only the .o files that you want to link? 

Also I think there should be a linker script for GCC - would be good to know what is in there.

Hi Anthony,

Thank you for your reply.

The previous report and errors was the result from trying to compile on my Windows 7 machine. On my Linux machine I am still getting an error while linking, but it is different error message. This is the report I get on my Linux machine:

I haven't tried your suggestions yet, but I looking into it right now. I'll post back as I get to it.

I figured out why I get different errors on windows and on linux. The linker script file "sys_link.ld" (that was created with HalCoGen on Windows) has two file paths with the backslash "\" as directory delimiter. To be exact in lines 43 and 44. I repeat the code here for clarity:

 /* FreeRTOS Kernel in protected region of Flash */
  .kernelTEXT :
  {
    . = ALIGN(4);
    KEEP(*(.kernelTEXT))
	KEEP(source\sys_startup.o(.rodata))
	KEEP(source\os_tasks.o(.rodata))
    . = ALIGN(4);
  } >KERNEL

I edited the file changing the backslashes to forwardslashes, and now I get the same "multiple definition" errors on Linux as I did on Windows. Fixing this error gave me a clue of why I might be getting those multiple definition errors. If you look at the linker script, you'll see that the files those paths make reference to are "sys_startup.o" and "os_tasks.o". These files are the ones that contain all the functions that are getting defined twice. So it seems like it gets linked from the script file once and again from the linker command line. I'm not sure if this is really the source of the errors or how to fix it. I am guessing I should remove those files from the linker command line, which is automatically constructed by CCS. CCS handles these files in the ${inputs} environment variable.

If anyone has a clearer idea of how to go about doing this, it would be appreciated.

Martin.
