Использование wpa_supplicant в своих программах

29.05.2012, 12:44. Показов 3225. Ответов 8
Метки нет (Все метки)

Здравствуйте, коллеги!
Воспользовался поиском, да ничего не нашел по интересующей теме.
Собственно, прошу помощи в таком вопросе. Мне необходимо написать своё приложение, использующее wpa_supplicant для работы с Wi-Fi. Моё приложение будет вызывать функции поиска сетей, установку соединения, передачи парметров ip, gateway, dns-сервера и т.п. То есть, другими словами, мне необходимо написать свой собственный wpa_cli. Это, конечно, грубо говоря. Пишу это не ради праздного интереса. Это часть проекта. Прошу хоть какой-то помощи.
На данный момент ознакомился немного с документацией, но не могу разобраться с такой ситуацией. В моем файле исходных кодов указаны все #include, как и в исходниках wpa_cli, но почему-то при компиляции выдается ошибка
Код
(.text.startup+0x11):-1: ошибка: undefined reference to `wpa_ctrl_open'
. Мне дали совет, что необходимо сначала собрать библиотеку wpa_ctrl.c, а потом уже её подключить в проект. Как это сделать? И вообще, кто по этому поводу что-то знает, подскажите, пожалуйста.

Легально ли использование шрифтов Windows в своих программах VB
Тема с лицензиями на шрифты довольно интересна и актуальна. Наверное вопрос уже сто раз обсуждался,...

Lucky_spirit, попробуй поискать строку компиляции для wpa_cli. Программа должна линковаться с какой-то библиотекой с помощью параметра -l"имя библиотеки".То есть ты эту команду добавляешь в строку параметров компиляции. Например, чтобы скомпилировать проект, использующий pthreads, обычно добавляют -lpthreads .
wpa_cli тоже наверняка линкуется с какой-то библиотекой, где присутствует функция wpa_ctrl_open.

Как вариант, можно попробовать просто добавить -lctrl (я просто попытался угадать, может, там что-то другое)

#pragma, спасибо за совет, но я не знаю строку компиляции wpa_cli, потому что эта строка, скорее всего, находится где-то в Makefile. Я пока еще не владею такими знаниями, чтобы подсмотреть их оттуда. У меня такие догадки насчет решения моей проблемы. Итак, напишу по порядку.
Я подключаю wpa_ctrl.h файл и wpa_ctrl.c. Соответственно, в одном файле описание, в другом - реализация. Но интересный момент заключается в том, что в файле wpa_ctrl.c есть несколько реализаций нужных мне функций. Они лишь заключаются в #ifdef, #endif. Возможно, мне необходимо как-то в своем классе в самом начале написать #define что-то? Привожу исходный код обоих файлов.

... интересный момент заключается в том, что в файле wpa_ctrl.c есть несколько реализаций нужных мне функций. Они лишь заключаются в #ifdef, #endif. Возможно, мне необходимо как-то в своем классе в самом начале написать #define что-то?
Из того, что я увидел в коде, функция, которая даёт ошибку, как раз наоборот, не заключена в команды препроцессора, и ошибка
Код
undefined reference to `wpa_ctrl_open'
обычно указывает на успешную компиляцию, но ошибочную линковку. То есть, искать проблему нужно где-то или в среде, где работаешь (например, не подключились файлы в проект, или компилятор не видит библиотеку, и т.д.), или, если компилируешь в консоли, в правильной строке, подаваемой компилятору. Можно попробовать скомпилировать отдельно библиотеку с флагом -fPIC (как динамическую), и затем использовать в проекте. Можешь почитать это сообщение от Evg, там он немного объясняет, как компилировать и почему Можно ли как-то указать в Makefile, чтобы часть файлов компилировал компилятор C? . Можно ещё пошарить по форуму или в гугле на предмет использования разделяемых и не разделяемых библиотек в программах.

#pragma, а можно ли выделить правильную строку компилятора из Makefile? Просто wpa_cli.c находится в папке с самим суппликантом и у него нет файла проекта или хотя бы файла main.cpp. В самом файле wpa_cli.c есть функция main. Так вот, когда я вызываю команду make в папке, то компилируется и wpa_supplicant, и wpa_cli. Я так понимаю, что та строка должна быть в Makefile. я на правильном пути?

ессно
приведите текст Makefile
хотя на самом деле
make clean
make
должен показывать с какими ключами программа компилируется

В общем, помогли мне на другом форуме. Всё оказалось проще, чем я думал. Нужно было просто добавить в свой проект файлы wpa_ctrl.c и wpa_ctrl.h. Но не просто написать где-то #include, а именно так, как будто они созданы мною. То есть в списке файлов проекта они у меня были в разделах исходных кодов и заголовочных файлов. И в самом wpa_ctrl.c нужно было дописать в начале строку #define "какой-то вариант подключения к впа_суппликанту" . Всё, после этого заработало. Приложение, правда, нужно запускать от root пользователя. Но это уже особенность самого впа_суппликанта.
