Я пытаюсь использовать любой из сторонних анализаторов XML на основе libxml, но не могу, потому что думаю, что у меня какая-то проблема с libxml2

Я установил другие флаги компоновщика на -lxml2

и пути поиска заголовка к / usr / include / libxml2

но я все еще получаю кучу неопределенных символов, когда пытаюсь скомпилировать. Приведенные ниже ошибки являются результатом попытки скомпилировать TouchXML.
