Почему тут string не видит, когда пытаюсь подключить свой модуль?

Question

[EGGOFFOX]

Нужно подключить свой модуль с функциями к модулю в котором находиться менюшка с вызовами этих функций , но не получается , почему ошибки со стрингом хотя с time.h все вроде хорошо

Answer 1

[Иван Соломенников]

Потому что string находится в пространстве имен - std.

std::string

Либо заюзайте: using namespace std::string

Помогло только теперь
undefined reference to" mySpace::fun" появились

[Иван Соломенников]

EGGOFFOX, Неопределенная ссылка к fun пространства имен mySpace, смотрите есть ли там fun в пространстве имен mySpace.

[EGGOFFOX]

Иван Соломенников,
Да , только там вообще все функции с такой ошибкой :(

EGGOFFOX, Что это за функция? showMyrecords(myRecords, amountRecords); В коде только ее вызов, никакого тела функции нет.

[EGGOFFOX]

Иван Соломенников, там все функции есть просто из-за ограничения коментов несколько функций пришлось удалить

[Иван Соломенников]

EGGOFFOX, в main.cpp после хидеров -

using namespace std;
using namespace mySpace;

В functions.cpp - using namespace std; и + весь код включая структуру оборачивайте в пространство имен mySpace так как в заголовочном файле у вас структура и прототипы находятся в этом пространстве имен.

[EGGOFFOX]

Я понял , у меня заработало только когда я в коде блоксе создал проект и добавил туда все вот это , но есть вариант как то самому без проекта собрать ?

[Иван Соломенников]

EGGOFFOX, да, как вариант из functions.cpp создаете библиотеку и линкуете ее при компиляции основного файла(main.cpp).
