Я пытаюсь кросскомпилировать azure iothub sdk, написанный на C, для шлюза ARM. Этот шлюз снабжен кросс-компилятором.
Мне нужны библиотеки и включает в себя iothub для разработки на шлюзе. Я без проблем загрузил и скомпилировал zlib, curl, openssl и libuuid для устройства ARM. В настоящее время я застрял на этапе компоновки кросс-компиляции. Для компиляции sdk используется Cmake, поэтому я предоставил файл цепочки инструментов cusom для настройки путей и каталогов в моей среде разработки.
Это конфигурация системы:
- ОС: Linux 2.6.36
- Архитектура: ARM9
- Версия пакета SDK для Azure IoTHub: 03.11.2017
файл цепочки инструментов (toolchain.cmake):

Чтобы скомпилировать SDK, я запускаю следующие команды внутри / sdk / directory / cmake /:
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake -DCMAKE_INSTALL_PREFIX=/opt/crosstool/arm-none-linux-gnueabi/arm-none-linux-gnueabi/libc/usr/
cmake --build .

Я пытаюсь выяснить, какую библиотеку или директиву ссылки мне не хватает, потому что я думаю, что неправильно ссылаюсь на скомпилированную библиотеку, но я еще не смог найти решение. Есть кто-нибудь, кто уже решал подобную проблему?
