在Vitis下运行DNNDK例程时，（例程地址https://github.com/Xilinx/Vitis-In-Depth-Tutorial/blob/2020.1/Vitis_Plat...）运行到编译时，（20 Right click the hello_dpu project folder and select Build Project）一直出如下错误：

解决方法
以上错误是由于虚拟内存空间太小导致，扩大SWAP区域空间，由2G改成8G。执行如下步骤修改虚拟内存：
查看虚拟内存空间:
free –h
停用SWAP空间:
sudo swapoff –v /swapfile sudo rm /swapfile
创建swap文件:
sudo dd if=/dev/zero of=swapfile bs=1G count=8
修改swapfile文件权限:
sudo chmod 600 /swapfile
设置Linux SWAP区域：
sudo mkswap /swapfile
激活SWAP文件：
sudo swapon /swapfile
再次查看虚拟内存空间是否设置成功:
free –h
设置成功后再进行编译，结果正常。
