从源

Question

我想从源代码安装pkgconfig，因为我想让它在我的应用程序访问的特定路径中。但是我遇到了一个问题，这对于非常熟悉C / C ++的人来说似乎很基础。我试图搜索解决方案但没有成功。问题在于end_time的定义是来自下面的make show的摘录

In file included from gthread.c:42:0:
gthread-posix.c: In function 'g_cond_timed_wait_posix_impl':
gthread-posix.c:112:19: error: storage size of 'end_time' isn't known
struct timespec end_time;
gthread-posix.c:112:19: warning: unused variable 'end_time' [-Wunused-variable]
Makefile:285: recipe for target 'gthread.lo' failed

文件＆＃34; pkgconfig-0.23 / glib-1.2.10 / gthread / gthread-posix.c＆＃34;中的第112行。在错误的起源（包括之前的一行和之后的几行）是

{
int result;
struct timespec end_time;
 gboolean timed_out;
g_return_val_if_fail (cond != NULL, FALSE);
g_return_val_if_fail (entered_mutex != NULL, FALSE);
if (!abs_time)
{
g_cond_wait (cond, entered_mutex);
return TRUE;
 }
end_time.tv_sec = abs_time->tv_sec;
end_time.tv_nsec = abs_time->tv_usec * (G_NANOSEC / G_MICROSEC);

g_assert (end_time.tv_nsec < G_NANOSEC);
result = pthread_cond_timedwait ((pthread_cond_t *) cond,
                               (pthread_mutex_t *) entered_mutex,
                               &end_time);
#ifdef HAVE_PTHREAD_COND_TIMEDWAIT_POSIX
timed_out = (result == ETIMEDOUT);

#else
timed_out = (result == -1 && errno == EAGAIN);
#endif
  if (!timed_out)
    posix_check_for_error (result);
  return !timed_out;
}

任何帮助将不胜感激
