Generate executable code on another platform. Why is cross-compilation costly? One sentence: The last thing is. Sometimes it is because the target platform does not allow or cannot install the required compiler, and some features of the compiler are required. Sometimes it is because the resources on the target platform are poor, it is impossible t

Linux-Raspberry Pi system partition
There are two main partition commands: fdisk and parted.Both commands require the root permission,First, we will introduce the fdisk command: Fdisk allows you to view the usage of the current file system.
fdisk -l
Because I installed the system on the SD card, the partition starts with/dev/mmcblk0. We can see that there are currently three actual partitions (/dev/mmcblk
