Unknown type name 'uint32_t'. Как приручить?

Пробую вкомпилировать jansson (парсер json) в свой проект (с++) . Выдает ошибку Unknown type name 'uint32_t'.

попробуйте подключить заголовок stdin.h или объявить этот тип так:

#ifndef __uint32_t_defined
typedef unsigned int		uint32_t;
# define __uint32_t_defined
#endif

Почему не собрать jansson отдельно как статическую библиотеку и просто не подключить к проекту?

Ну видимо надо объявить HAVE_STDINT_H при компиляции.
