У меня проблема с компиляцией MySQL-коннекторов C ++ с помощью mingw, как выложено на официальном сайте, вы должны запустить cmake для настройки исходного кода, а затем запустить mingw32-make … на cmake должна быть установлена библиотека boost, поэтому я получил и скомпилировал (там написано, что много обновлено, 40 целей пропущено и 24 не удалось обновить).
После того, как он попытался запустить cmake на источнике коннектора mysql, он не выдает ошибок и работает просто отлично, при попытке выполнить последний шаг mingw32-make, он выдает много ошибок, многие из которых являются переопределениями … журнал приведен ниже. Пожалуйста, помогите мне, мне действительно это нужно.

К сожалению, исходный код MySQL коннектора c ++ является мусором.
Он переопределяет функции, которые определены в стандартной библиотеке, а затем включает стандартную библиотеку или зависит от нестандартных функций, которые не включены в каждую реализацию.
Так как стандартная библиотека не проверяет, были ли уже определены ее функции и структуры, вы можете столкнуться с множественными ошибками определения повсюду.
Кроме того, проблема усугубляется тем, что соединитель mysql не был портирован для mingw. Для компиляции на окнах вам необходимо использовать Visual Studio.
Становится лучше. Они поддерживают только визуальные студии 8 и 9.
Если вы точно будете следовать этим инструкциям,
http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-installation-source-windows.html
тогда вы могли бы заставить его работать, но вы не должны отклоняться от номеров версий. Используйте старую версию cmake, старую версию visual studio. Они не тестировали и не заботятся о совместимости с любыми современными версиями инструментов сборки.
Других решений пока нет …
