Unable to locate package zlibc when installing the kernel module #39

Open StanPlatinum opened 1 year ago

StanPlatinum commented 1 year ago

The readme in kernel-module indicates that the following dependencies should be installed for building the dm-jindisk kernel module.

sudo apt install dpkg-dev libncurses5-dev openssl libssl-dev build-essential pkg-config libc6-dev libc6-dev flex libelf-dev zlibc minizip libidn11-dev libidn11-dev bison dwarves

But, the zlibc cannot be located on Ubuntu 22.04.

Actually, we don't need zlibc to build the kernel module. I have tested it without the zlibc support many times. Can we remove it?

Sure, zlibc may only be necessary on some old kernel. You can check kernel documentation for the Minimal requirements to compile the Kernel. And as it says:

not all tools are necessary on all systems.
