Oh yea that is what I was wondering it is only getting X86_64 toolchain, Now it have fetched the toolchain and I cleaned the build dir and tried to build again with correct target and it still failed with same error base_build.log have a single ling chroot: failed to run command 'env': Exec format error
Sorry for bugging you, Once I get the hang of it then I will be able to work on it myself.
Update1: I removed the toolchain and doing gettoolchain again for aarch64.
Stil it failed to build stage2 which is the first package to build in the list.
chroot: failed to run command env: Exec format error.
I have updated the whole system so make sure all packages are latest.
Update2: I am on Manjaro Arch Linux so I will look into it as the native chroot is not working i guess.
