当调用函数 rt_dev_ioctl 时，提示： undefined reference to `_rt_dev_ioctl'
我在程序中已经包含的头文件如下：
#include <sys/mman.h>
#include <sys/time.h>
#include <unistd.h>
#include <stdlib.h>
#include <math.h>
#include <stdio.h>
#include <string.h>
#include <signal.h>
#include <getopt.h>
#include <time.h>
#include <native/task.h>
#include <native/timer.h>
#include <native/sem.h>
#include <rtdm/rttesting.h>
还差头文件吗？

你需要连接到：librtdm

Hi,Yi:
是哪个目录的lib呢？我已经包含了/home/uClinux-dist/staging/usr/lib，里面有rtmd的链接库啊...

缺省应该编译librtdm.a (或者librtdm.so)的，我也不清楚为什么你那边没有。你可以看看xenomai的编译过程，是否编了librtdm.

我直接make编译，编译里面的那个例程latency.c都过不去，Makefile如下：
XENO_PATH = /home/uClinux-dist/staging/usr
CFLAGS = -I$(XENO_PATH)/include -I/usr/include/
LDFLAGS = -L$(XENO_PATH)/lib -Wl,-elf2flt
CC =bfin-uclinux-gcc
LDLIBS += -lnative -lm -lpthread
EXEC=main
OBJS=main.o
all:$(EXEC)
$(EXEC):$(OBJS)
$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $(OBJS) $(LDLIBS)
