Re: "incompatible target" when trying Gold linker for arm-none-eabi

Hallo Cary:

Many thanks for your answer.

I am using the GCC driver, but "-Wl,-t" did not make any difference in 
the output. However, I just noticed the following messages after all 
other errors:

I realised I was not building Gold with plug-in support, so I am doing 
it now. Maybe that would fix the other errors too.

I came across someone else with this problem, so I am not the only one 
hitting this issue:

https://stackoverflow.com/questions/23754665/gold-linker-ld-gold-plugin-unknown-option

I think Gold should always accept options -plugin , --plugin , or 
whatever it can take. If it has not been built with plug-in support, 
then it should print an error message that says exactly that. This way, 
other users will not waste their precious time too anymore. 8-)

Is this right? Should I file a bug somewhere about this?
Best regards,
