Error "Multiple definition of '...'"

Having updated Crossworks for ARM from vs. 2.0.11 to vs. 2.1.1, I get that "Multiple definition of '...'" error message.

The variables that are concerned are declared in different modules and I did not have that problem with vs. 2.0.11.

Is there a new property that defines all variables as globals?

Does anybody know a solution?

  Perhaps I should mention that at the same time I get the error message "error: .data is too large to fit in FLASH memory segment". This message comes from the linker script.

  As mentioned previously, with vs. 2.0.11 no such message came up.

  Did you try setting the "No COMMON" property to be "No" - there are some words on this in the release notes.

  Hello Michael,

  I have set the "NO COMMON" property to NO and the Multiple Definitions error is gone.

   

  What still remains are the following error messages from the linker script file:

  ".data is too large to fit in FLASH memory segment"

  ".rodata is too large to fit in FLASH memory segment"

  ".fast is too large to fit in FLASH memory segment"

  I normally would think that the linker script is the reason for that, but it was ok with Crossworks vs. 2.0.11

  Would you have a suggestion for that issue?

  Regards,

  Henry

  Hi Henry,

  Did you turn off "Enable Unused Symbol Removal"? If so then all the C library will be linked in to the application.

  Hello Michael,

  that seems to be a new behaviour. With a previous version it did not matter if it is YES or NO.

  After having now set "ENABLE UNUSED SYMBOL REMOVAL" to YES there are no more error messages.

  Thank you for your immediate help.

  Regards,

  Henry
