undefined reference to `_conf_os
本帖最后由 wirelessgo 于 2014-10-30 13:50 编辑出现这个问题 涉及到3个文件
main.c 内容：
#include <p33FJ32MC204.h>
#include "conf_bit.h"
#include "conf_osc.h"
#include "car_rtdm_test.h"
#include "RTDM.h"
#include "RTDMUSER.h"
int main(){
conf_osc();
conf_bit();
test_rtdm();
return 0;
}
conf_bit.h

extern int conf_bit(void);
#endif /* CONF_BIT_H*/
conf_bit.c
#include <p33FJ32MC204.h>
#include "conf_bit.h"
