Unrecognized option '-Wl,--mgen-symbol-ld-script=export.txt'

Hi Kelong

it looks like you are using Keil MDK so you may get a higher qualith answer in that forum. 

My guess from the error message is that the string in that box is passed to armlink so needs to be valid armlink options. -Wl, is not an armlink option, it is an armclang option to prefix other options that you want to pass to the linker when invoking it from the compiler driver (including when compiling and linking in one step.) So I would forst remove the -Wl, prefix. 

You then need to check in your manual whether mgen-symbol-ld-script=export.txt is also a valid armlink option. It looks wrong to me, I think armlink doesn’t support GNU linker scripts. I am guessing you might be looking for the —symdefs option given that you pass a scatter file in the below box. But my knowledge of armlink’s commandline is out of date so you are better off asking in the Keil forum.

Hope that is helpful
