The option '-Wl' is used to pass options to linker, for example the command line "arm-none-eabi-gcc -Wl,-Map=test.map ..." will pass linker option "-Map=test.map" to gnu linker at link stage. For your issue, it looks like the project doesn't use this option in a proper way. Can you please share how you create your project in CooCox, so that we can reproduce the issue and find the cause?

It is an IDE problem rather than compiler. This should fix it:

Can you help with this problem?
