手動指定 main 函數做爲入口libvcruntimed.lib

若是必定要這樣作能夠使用下面的方法手動連接運行庫。
#pragma comment(lib, "msvcrtd.lib")
#pragma comment(lib, "vcruntimed.lib")
#pragma comment(lib, "ucrtd.lib")
須要根據本身的編譯選項來肯定連接哪些庫
Release DLLs (/MD ): msvcrt.lib vcruntime.lib ucrt.lib
Debug DLLs (/MDd): msvcrtd.lib vcruntimed.lib ucrtd.lib
Release Static (/MT ): libcmt.lib libvcruntime.lib libucrt.lib
Debug Static (/MTd): libcmtd.lib libvcruntimed.lib libucrtd.lib
