Zubax_gnss firmware compile failed

Hello, I have an error when compiling Zubax_gnss, but I don’t know how to solve it. Can someone answer it for me? Maybe this is a little white question!

I already Install ARM GCC toolchain version 6.3 or newer

If you read the error message, it clearly indicates that the compiler does not support the flag -Wimplicit-fallthrough, which implies that it is of a wrong (old) version.

Hello, this is the version I am currently using, do I need to update it?TIM%E6%88%AA%E5%9B%BE20190505115330

This version should work. If it still doesn’t, perhaps you have another version installed which is not working. Otherwise consider upgrading to 7.3 and use the current master.
