Ошибка сборки libpthreads-stubs-0.3 в Windows

Я пытаюсь скомпилировать libpthreads-stubs-0.3 (для vaapi) на машине с Windows, которая имеет среду MinGW и MSys. Я установил пакет mingw32-pthreads-w32 dev (версия 2.9.1-1) в MinGW.

Теперь, когда я пытаюсь скомпилировать libpthreads-stubs-0.3 (есть только один файл с именем stubs.c) я получаю ошибку конфликтующих типов:

make  all-am

Теперь, когда я комментирую #include <pthread.h> в верхней части файла и положить его внутрь ifndef (потому что, если я не получаю, я получаю ошибку: error: unknown type name 'pthread_t' что очевидно) я получаю ту же ошибку, что и выше:

#ifdef NEED_EQUAL_STUB
#include <pthread.h>
static int __pthread_equal_stub(pthread_t t1, pthread_t t2)
{
    return (t1 == t2);
}
#endif

Я не могу воспроизвести вашу ошибку, но (думаю) успешно установил libpthreads-stubs-0.3. Я использую 64-битную версию msys и mingw.

Я скачал libpthreads-stubs-0.3 с этого сайта, использовал tar -xzf, чтобы распаковать его в мою домашнюю папку в msys, cd'd в папку и сделал ./configure --prefix=/usr затем make затем make install,

У меня когда-то был error: conflicting types for ... а также error: previous declaration for ... и это было потому, что я включил pthreads.h mingw в одном месте и другую версию pthreads.h для Windows в другом месте.

Если ничего не помогает, попробуйте начать заново с установки mingw и libpthreads-stubs-0.3.
