| 我编译时总报错,提示找不到变量定义,可是我不知道需要那个头文件?在sopc builder中，我选择了生成sdk，但是我使用的是ide开发环境，在别的文章中说需要include system.h ，不需要include excalibur.h,此外，生成的sdk中的头文件是不是就是我需要的？怎么用呢？可能sdk与我的源程序不在同一个目录。在属性对话框里面设置了路径也不对。谢谢！
======================
#include
#include "system.h"
int main()
{
na_timer1->np_timerperiodl = (short)(nasys_clock_freq & 0x0000ffff);
na_timer1->np_timerperiodh = (short)((nasys_clock_freq >> 16) & 0x0000ffff); // Set timer running, looping, no interrupts
na_timer1->np_timercontrol = np_timercontrol_start_mask+ np_timercontrol_cont_mask;
return 0;
}
===================
make -s all
