ISO C++ запрещает объявление 'pthread_cond_t' без типа

Question

У меня возникают некоторые ошибки при попытке скомпилировать объектный код, который я изначально не написал. Платформа GNUstep в Windows 10. Я очень новичок во всем этом, поэтому я подозреваю, что делаю элементарную ошибку.

Помощь!

discuss-gnustep список рассылки при условии, что решение: #import <pthread.h> был в неправильном месте. Это должно быть в EngineController.h вместо main.m
