Please describe your issue below:
Cannot build an Android Kernel.
I believe it’s related to cross compile tooling setup, but have no idea to fix it.
The host OS is Ubuntu 20.04 amd64.
And, one missing package is “gcc-4.8-aarch64-linux-gnu” which does not exist on Ubuntu 20.04.
Post a console log of your issue below:
$ cd bootloader/uboot
$ ./mk kvim4 --avb2 --vab

build kernel error
My mistake. I was working on the wrong build environment. 
Hi @windchaser. Im have same error Ubuntu bionic 18.04. Can you elaborate on that? How fix ‘-EL’ and gcc-4.8-aarch64-linux-gnu?
Fix me:
aptitude remove gcc-multilib g++-multilib
aptitude install gcc-aarch64-linux-gnu cpp-aarch64-linux-gnu
export PATH=$PATH:/opt/toolchains/gcc-linaro-7.3.1-2018.05-i686_aarch64-elf/bin
export PATH=$PATH:/opt/toolchains/xpack-riscv-none-embed-gcc-8.3.0-1.2/bin
./mk kvim4 -v 5.4

Hello, @Greg798100.
I hope you fixed this already.
But just in case you didn’t…
- Follow the official build guides.
- I don’t think you need those additional PATH settings.
Just extract those additional tool chain files to the right directory as official guide says.
VIM4 uses different versions of build tools per project. And the build script controls when to use which executables.

installed, and make, but have same error ld.lld
@Greg798100 I suspect that the compilation problem is caused by your failure to synchronize good code. Please resynchronize the code to confirm that there is no error in the synchronization process.
Yes, build five hours and the end errors
