Hello Everyone, This week, I had relatively less work done. I spent most of my time perusing the LFS guide and osdev.org learning about building toolchains. Then I went onto building the aarch64-linux-android toolchain as described in [1]. I updated the kernel sources for my phone [2]. And in general tidied up my kernel repository. But while building the toolchain, I was not able to compile `gcc` as I was riddled with errors along the way. Most of them are related to the newer `gcc` (version 9.x) finding incompatibility in the sources of the `gcc` I am trying to build (version 4.9). I will continue to build the toolchain and hopefully move onto separating `Bionic` from the other side of Android mid-week. Thanks, Gunwant [1] https://wiki.gentoo.org/wiki/Android/SharkBait/Building_a_toolchain_for_aarch64-linux-android [2] https://github.com/WantGuns/overlay/blob/master/sys-kernel/linux-headers/linux-headers-4.4.222.ebuild
