Overflowers!
Я разрабатываю статически связанное приложение с помощью Visual Studio 2010 (ну, это кросс-платформенный, но это просто проблема с Windows).
У меня было несколько проблем, связанных с настройкой конфигурации Debug, поэтому я не ожидал, что изменить конфигурацию будет сложно, но после дневной работы она все равно ускользает от меня. Пытаясь использовать различные значения для NODEFAULTLIB, вы получите ошибки "неразрешенных внешних символов" или "уже определенные в" ошибках, а иногда и то и другое.
Из моих заметок я пробовал NODEFAULTLIB-ing LIBCMT, MSVCRT, MSVCPRT или вообще ничего с разными результатами каждый раз (подробнее см. ниже).
Теперь моя конфигурация Debug использует /NODEFAULTLIB: MSVCRTD/NODEFAULTLIB: MSVCPRTD, и это работает отлично, поэтому вы думаете, что /NODEFAULTLIB: MSVCRT/NODEFAULTLIB: MSVCPRT будет работать для конфигурации Release. И тот факт, что он не является для меня красным флагом...
Я связываюсь с несколькими другими библиотеками - я был довольно осторожен, чтобы систематически следить за тем, чтобы они считались одинаковыми при переходе от Debug к Release, но может ли это быть проблемой, и если да, то как отслеживать ее систематически
Спасибо за ваше любезное время!

Лучше всего:/NODEFAULTLIB: LIBCMT
