Question

虽然编制在Ubuntu一个makefile 12.04 LTS（64位），这些错误会遇到，

fifo.c: In function ‘OpenPipe’: 
fifo.c:28:3: warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat]

return 0; 
} 

顺便说一句，我添加以下行到.profile：

出口FIFO0 = /家庭/巴亚特（Bayat）/ FIFO0

出口FIFO1 = /家庭/巴亚t/fifo1

请帮我解决它们。 在此先感谢。

Answer 1

如果你看看（可能在fifo.h），你会发现，fifo0和fifo1被定义为int当你的程序显然希望他们成为一个char *或char[]我的期望。可能你需要的是这样的代替：

char fifo0[] = "/home/bayat/fifo0"; 
    char fifo1[] = "/home/bayat/fifo1"; 

我不认为你的.profile文件在这里有什么影响。
