Как заполнить BYTEARRAY?

Question

[Кирилл Жиляев]

Никак не пойму как записать в BYTEARRAY байты. Как это сделать?
Это крашит приложение

BYTEARRAY Data;
	Data[0] = 0x54;
	return Data;

Как объявлено BYTEARRAY?

[Кирилл Жиляев]

res2001, Вот так оно и объявлено
BYTEARRAY Data;
Data[0] = 0x54;
return Data

[Adamos]

Сначала надо подключить библиотеку libastral и понять - а что, собственно, на самом деле скрывается за типом BYTEARRAY.

[res2001]

Кирилл Жиляев, Так объявлено Data.
Я спрашивал именно про BYTEARRAY, т.к. это не стандартный тип данных.

[Илья Герасимов]

res2001, BYTEARRAY посмотри как определен этот тип, char, int или что?
char bytes[1] = { 0x54 };

[Кирилл Жиляев]

std vector BYTEARRAY

[res2001]

Кирилл Жиляев, Ну вот и работайте с ним как с std:vector:
Таким определением:
BYTEARRAY Data;
Вы объявляете пустой вектор, а значит у него нет нулевого элемента.
Так можно добавить в конец ваше число.
Data.push_back(0x54);
Но лучше сразу объявить нужное количество элементов:
BYTEARRAY Data(100); // вектор Data из 100 элементов

Если не секрет что тут не так?

[res2001]

Кирилл Жиляев, В тексте ошибки все сказано:

has no member named ‘filename’

В классе directory_entry (указателем на экземпляр этого класса является ипеременная i) нет члена filename.

[Кирилл Жиляев]

res2001, А как портировать подобное под Linux?

[res2001]

Кирилл Жиляев, Что именно? Кроме ошибок тут ничего не видно.
boost - кроссплатформенный.
Консольное приложение с использованием boost должно собираться и под линуксом (если там не используется что-то специфическое для windows).

PS: Вместо i->filename() попробуйте i->path().filename(). В документации написано, что filename() - deprecated возможно в той версии, которую используете вы этот метод уже удален.

res2001,
Ту ошибку устранил. Под WIndows прекрасно компилируется с такой же версией бустов

Видимо надо добавить поддержку pthread, на сколько помню это делается опцией компиляции: -pthread
