TOO MANY compile errors after I created a new project

[MJ Ma]

I just got the nRF52-DK, and want to create a blank project to test something , but after I create a project and add "nrf_Log" module form RTE Manager(some conflict resovled by RTE Manager), so many compile error arise..... How do I do ?

well，thanks , seems I should check the "C99 mode" in c/c++ compile option page
