我在编译 C 程序以将声音从 Intel Edison 流式传输到设备(iOS 和 Android)时遇到了几个问题。
我做了一个 C 程序:我在我的程序中使用 alsa/asoundlib.h 和 pthread.h 我不包括 sys/time.h 因为 ALSA 不允许这样做。
我在我的程序中使用了很多 timeval,当我在我的计算机上编译它时,它编译得很好,但是在我的爱迪生上,当我:
gcc -std=c99 -Wall -O0 -ggdb -o sender sender.c spsc_circular_queue.c -lopus -lasound -lpthread
In file included from /usr/include/alsa/asoundlib.h:49:0,

我怎样才能阻止这些重新定义?!谢谢您的帮助 !
额外信息:
我包括:
#include <assert.h>
#include <stdbool.h>
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <errno.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <unistd.h>
#include <alloca.h>
#include <limits.h>
#include <inttypes.h>
#include <alsa/asoundlib.h>
#include "../opus/include/opus.h"
#include <pthread.h>
#include "spsc_circular_queue.h"
我删除了 sched.h,没有任何反应
